6 Best Crib Hardware Replacement Kits (October 2026)
The best crib hardware replacement kits include the XOOL 110 PCS M6×80/65/55/45/35 mm Hex Socket for Delta crib hardware, the Lhazemu 100pcs Baby Bed Crib Screws Hardware for five common lengths, and the Lhazemu 85Pcs Crib Screws Baby Bed Crib for the widest length range.
On this page (5 sections)
The best crib hardware replacement kit is one that matches your crib's exact model and original hardware dimensions. Of these six M6 assortments, XOOL is the top pick for its five lengths and stated suitability for Delta cots, but no kit should be treated as a confirmed fit without checking the model.
Replacement crib hardware can look interchangeable while differing in bolt length, thread, head shape or barrel nut dimensions. Start with the crib manual or manufacturer support, then compare the original part with the kit.
For the checks to make before choosing a set, see How to Choose Crib Hardware: What to Know. If your crib is a named model, its model-specific guidance may be more useful: Babyletto Hudson crib hardware, Storkcraft crib parts replacement and Pottery Barn crib hardware.

Which crib hardware replacement kits stand out?
The strongest options here offer a useful spread of lengths and include matching connector parts or a tool. The product information does not verify fit for every crib model, so use these as assortments to compare against your original hardware.
We compared the stated bolt lengths, included nuts and tools, and any named crib compatibility. Our score weighs specs, features and buyer feedback against what you're shopping for.
A higher score reflects a closer match to this roundup's needs, not a guarantee of fit.

XOOL 110 PCS M6×80/65/55/45/35 mm Hex Socket: Best for Delta crib hardware
- M6 bolts in 35, 45, 55, 65 and 80 mm lengths
- Steel with zinc plated finish
- Hex wrench and nuts included
- Portable plastic box
Five bolt lengths give you options when the crib uses M6 hardware, and XOOL says the set is particularly suitable for Delta cots. Match the exact bolt and nut requirements before ordering.
Pros
- Five bolt lengths
- Hex wrench and nuts included
- Plastic storage box
Cons
- Does not include every common M6 length
- Model compatibility still needs confirmation
XOOL has five M6 bolt lengths: 35, 45, 55, 65 and 80 mm. That set of options can help if you already know the crib needs one of those lengths and want a choice that names Delta cots as a particularly suitable application.
The kit includes a hex wrench and nuts, with the pieces stored in a plastic box. XOOL describes the screws as steel with a zinc plated surface.
Its length range skips 40, 50, 60 and 70 mm, so measure the original bolt rather than assuming the closest size will work.
Choose this set if your crib's manual or manufacturer confirms the required M6 hardware and one of these lengths. XOOL's Delta mention is a useful lead, but it does not confirm every Delta model or every crib connection.

Lhazemu 100pcs Baby Bed Crib Screws Hardware: Best for five common lengths
- M6 bolts in 40, 50, 60, 70 and 80 mm lengths
- 50 barrel nuts
- Hex key included
- Clear storage box
The five-length set includes barrel nuts and a hex key for M6 furniture connections. Lhazemu describes it as fitting most cribs, but that broad wording does not confirm a particular model.
Pros
- Five bolt lengths
- Barrel nuts and hex key included
- Storage box
Cons
- No 20 or 30 mm bolts
- Confirm compatibility with your crib model
Lhazemu's 100 piece assortment has M6 bolts in 40, 50, 60, 70 and 80 mm lengths, plus 50 barrel nuts and a hex key. It also comes in a clear storage box.
That range includes several common lengths, but it does not include 20 or 30 mm bolts. Lhazemu describes the set as compatible with most cribs, though that does not identify a specific make or model.
Pick it when the model and measurements match one of its five lengths. Confirm that the barrel nuts suit the crib's connector openings and follow the maker's instructions for replacing fasteners.
Lhazemu 85Pcs Crib Screws Baby Bed Crib: Best for the widest length range
- M6 bolts in seven lengths from 20 to 80 mm
- Barrel nuts and wrenches included
- Steel with zinc finish
Seven lengths cover more short and long options than the other sets here. Its broad furniture use does not confirm fit for a specific crib, so compare the original hardware first.
Pros
- Seven bolt lengths
- Includes barrel nuts and wrenches
- For cribs and other furniture
Cons
- Specific crib models are not named
- Check whether the included pieces match your hardware needs
This Lhazemu set covers seven M6 bolt lengths, from 20 to 80 mm in 10 mm steps. It also includes barrel nuts and wrenches, giving it the broadest stated length range among these picks.
The broad range may help when replacing mixed or missing fasteners, but the set is described for several kinds of furniture. No particular crib brand or model is named, so check your hardware dimensions and connection style before ordering.
Choose it if the original bolt measures one of the seven included lengths. A wide assortment cannot make an incorrectly sized bolt safe or suitable.
Glarks 141Pcs Baby Bed Crib Screws Hardware: Best for 20 to 80 mm options
- M6 bolts in seven lengths from 20 to 80 mm
- 70 barrel nuts
- Allen wrench included
- Bolts and nuts stored separately
This black metal set pairs seven M6 bolt lengths with 70 barrel nuts and an Allen wrench. The range is broad, but you still need to match the crib's hole spacing and original hardware.
Pros
- Seven bolt lengths
- 70 barrel nuts
- Allen wrench included
Cons
- Black finish may differ from the original hardware
- No named crib model compatibility
This Glarks kit includes M6 bolts in 20, 30, 40, 50, 60, 70 and 80 mm lengths. It pairs them with 70 M6x12 mm barrel nuts and an Allen wrench, with different sizes packed separately.
The bolts have a black finish. That may be a visible difference if the crib's original hardware is exposed, though appearance matters less than matching the exact connector and following the assembly instructions.
Choose this set for a confirmed M6 match when your required length falls between 20 and 80 mm in the included steps. It names cribs among its uses, but doesn't confirm a specific crib model.
Glarks 141Pcs Baby Bed Crib Screws Hardware: Best for 15 to 75 mm options
- M6 bolts in seven lengths: 15, 25, 35, 45, 55, 65 and 75 mm
- 70 barrel nuts
- Allen wrench included
- Black oxide finish
Choose this Glarks set when your measured bolt length falls among its 15 to 75 mm options. Its lengths differ from the other Glarks kit, so check each measurement carefully.
Pros
- Includes 15 and 25 mm lengths
- 70 barrel nuts
- Allen wrench included
Cons
- No 80 mm bolt
- Black finish may not match the crib
This second Glarks assortment has a different range: 15, 25, 35, 45, 55, 65 and 75 mm. It also includes 70 barrel nuts and an Allen wrench.
The bolt range overlaps the other Glarks kit, but neither includes every length. Compare the two sets against the original part instead of choosing by the shared brand or piece count.
This is the closer Glarks option when your measured length is 15, 25, 35, 45, 55, 65 or 75 mm. The stated black oxide finish may not look like the original hardware.
GDFYMI Crib Screws Replacement Set: Best for 15 to 75 mm bolts
- M6 bolts in seven lengths from 15 to 75 mm
- Barrel nuts and hex key included
- Clear storage box
This set covers seven M6 bolt lengths and includes barrel nuts and a hex key. Its listed materials differ across the product details, so confirm the exact version and parts before choosing it.
Pros
- Seven bolt lengths
- Barrel nuts and hex key included
- Clear storage box
Cons
- No 80 mm bolt
- Specific crib compatibility is not named
GDFYMI covers the same seven stated lengths as the second Glarks set: 15, 25, 35, 45, 55, 65 and 75 mm. It includes barrel nuts and a hex key, with a clear storage box described in the package details.
The product information gives differing material descriptions, so don't use a material assumption to judge whether it fits. Match the dimensions and connector style, and confirm the exact version before ordering.
Choose it if your crib requires one of these seven lengths and its hardware matches the included parts. The product name mentions Delta crib screws, but it does not identify a tested fit for a particular Delta model.
What should you check before buying replacement crib hardware?
Check the crib model first, then verify the bolt and connector dimensions against the manual or an original part. A replacement kit is only a candidate until each part matches the intended crib connection.
Use this checklist:
- Model: Find the brand, model name and model number on the crib or its paperwork.
- Bolt diameter and thread: These sets are M6, but that does not mean your crib uses M6 hardware.
- Length: Measure the bolt shaft, not the head. Compare the measurement with the kit's stated lengths.
- Head and tool: Check the head shape and the tool needed to turn it.
- Barrel nut: Compare its diameter, length and opening with the original connector.
- Condition: Look for damaged threads, stripped holes, cracked wood or bent metal around the joint.
If you can't identify a part, ask the manufacturer for the right replacement by model number. For a convertible crib, check whether the hardware instructions change with the configuration; our guide to the best convertible crib rail covers another part where model fit matters.
Does a larger assortment mean a better fit?
A larger assortment gives you more lengths to compare, but it does not guarantee compatibility. The seven-length Lhazemu and Glarks kits cover broader ranges than XOOL's five lengths, while the shorter-length Glarks and GDFYMI sets include options down to 15 mm.
The right choice depends on the crib's required parts. A box with more pieces can still have the wrong thread, barrel nut or bolt length for your model.
Can you use generic crib replacement hardware?
You can consider generic crib replacement hardware only when the dimensions and connection match the crib maker's instructions. A general-purpose label does not confirm fit for a specific crib.
Use a manufacturer-approved replacement when available. Don't modify a bolt, substitute a different connector or keep using a crib with a loose or damaged joint; contact the manufacturer if you cannot confirm the correct part.
Which crib hardware replacement kit should you choose?
Choose XOOL if your confirmed M6 hardware needs one of its five lengths and the Delta cot compatibility note applies to your model. Choose Lhazemu's 85 piece set for the widest length range, or one of the Glarks sets when its specific lengths match your original bolts.
For any crib, put model compatibility and exact measurements ahead of piece count. Start with the manual or manufacturer, then compare the replacement parts before assembly.

Frequently asked questions
How do I know which crib hardware replacement kit fits?
Check the crib's brand and model, then compare the original bolt diameter, length, head type and barrel nut dimensions with the replacement set. M6 alone does not prove fit because bolt lengths and connector details vary.
Use the crib manual or manufacturer support to confirm the required parts when the model is unclear.
Are universal crib hardware kits safe to use?
A kit described as universal still needs to match your crib's model and original hardware. Confirm that each bolt seats correctly with its barrel nut and that the connection follows the crib maker's assembly instructions.
Don't use a replacement part that binds, protrudes or leaves a loose joint.
Can I replace only one crib bolt?
You may be able to replace one bolt if you find the exact matching part for your crib model. Compare its length, diameter, head and nut, and check the remaining hardware for damage.
If the frame or connector is damaged, contact the crib maker for guidance before using the crib.
