Crib hardware kits are complete sets of screws, bolts, washers, and brackets designed to safely assemble or repair baby cribs. Using the correct crib hardware kit is essential for keeping the crib stable, properly aligned, and secure as your baby grows. This guide explains what crib hardware kits include, how to identify the right sizes for your crib model, and what to look for when replacing missing or worn crib hardware.

Crib Hardware Kits: What They Include and When You Need One

Crib hardware kits are designed to replace the exact screws, bolts, washers, and connectors that keep a crib frame tight, square, and stable. Parents usually land here after a move, a hand-me-down crib, a missing bag of parts, or a “one screw doesn’t match” moment during assembly. If that’s you, you’re not alone—and you don’t have to guess. This page will help you figure out what you need, how to identify the right kit for your crib, and what to avoid so you don’t create gaps, wobbles, or stress points.

Start Here: Identify Your Crib Model Before You Buy Anything

The fastest way to get the correct hardware is to identify your crib’s brand and model number. Look for a label under the mattress support, on the underside of the crib frame, or on the back of the headboard or footboard. If the label is missing or unreadable, check your original manual or packaging. When you have the model number, you can determine whether you need an OEM kit or a carefully measured compatible replacement.

Where parents get stuck most often

Hardware confusion usually happens when a crib has been disassembled before and parts were mixed together, or when one bolt is missing and a hardware-store substitute seems “close enough.” If you’re tempted to replace crib screws with something similar, read this first: Can You Replace Crib Screws With Hardware Store Screws?

How to Match the Right Crib Hardware Kit by Size and Thread

If you have the original screw or bolt—even a damaged one—you can usually match it reliably by checking length, diameter, thread type, and head style. Cribs typically use a mix of wood screws and machine bolts. The goal is a snug, seated connection with no gaps or movement.

Measurements that matter

Measure bolt length from the underside of the head to the tip. Check diameter carefully and pay attention to the thread. If you’re dealing with missing screws specifically, this guide can help: What to Do When Crib Screws Are Missing .

Common Types of Crib Hardware Kits Parents Shop For

Not all crib hardware kits are the same. Some are complete assembly kits, while others replace only specific connections. Knowing which category you need prevents ordering the wrong parts and delaying assembly.

Full crib assembly hardware kits

These are best when the entire hardware bag is missing or mixed. They often include multiple bolt lengths and washers, which means careful matching is important.

Side rail bolts and connectors

Side rail connections are critical for stability. These kits may include longer machine bolts, lock washers, and barrel nuts or threaded inserts.

Mattress support hardware

Mattress supports use screws, bolts, or brackets depending on the crib. If you’ve adjusted mattress height and discovered missing hardware, replace it properly so the support stays level. You may also find this helpful: Is It Safe to Use a Used Crib?

Step-by-Step: Replace Crib Hardware Without Creating Wobble

When replacing hardware, tighten everything gradually and evenly. Fully tightening one corner first can twist the frame and cause misalignment.

Tools most parents use

A Phillips screwdriver, the correct Allen key, and a basic wrench or socket set are usually enough. Keep bolts aligned to avoid cross-threading.

A tightening pattern that helps

Start all bolts loosely, then tighten each corner a little at a time. This keeps the crib square and prevents stress on joints.

What to Avoid With Crib Hardware (Even If It Fits)

Small differences in hardware can affect how weight is distributed and how joints behave over time. Screws that are too long, too short, or incorrectly threaded can compromise stability.

Red flags to watch for

If the bolt head won’t sit flush, the crib creaks when gently moved, or you see gaps between panels, stop and re-check the hardware match.

Check for Recalls Before Repairing

Before investing in repairs, it’s smart to check for safety recalls—especially for older or secondhand cribs.

Check the U.S. Consumer Product Safety Commission recalls database

When a Kit Still Doesn’t Match

If one piece still seems wrong, don’t force it. Compare it to the original hardware and confirm its role in the frame. Some cribs require model-specific connectors that universal kits don’t include.

Final Safety Check Before Use

Before placing your baby in the crib, confirm all bolts are snug, washers are in place, rails sit flush, the mattress support is level, and the frame does not rock. If anything feels unstable, pause and re-check the hardware.
