Simmons Crib Replacement Screws — What to Do When Parts Are Missing

Updated December 20, 2025 by Jan of Unique Baby Gear Ideas

Do you need Simmons crib replacement screws? That can be such a problem, especially when you’re ready to assemble the crib or make a small repair and everything has to come to a halt. Missing hardware is one of the most common issues parents run into with older Simmons cribs, but in many cases the problem can be solved by identifying the crib model and matching the correct replacement screws instead of replacing the entire crib.

How to Identify Your Simmons Crib Model

Before ordering replacement screws, it’s important to identify your specific Simmons crib model. Simmons produced many crib styles over the years, and screw sizes, thread types, and connector hardware can vary between models.

Most Simmons cribs have a manufacturer label attached to the inside of the headboard or underneath the mattress support. This label usually includes the model number, manufacture date, and sometimes a style name. Writing this information down will save time and help you avoid ordering the wrong hardware.

If you need the original parts diagram or assembly reference to help confirm screw placement, you can find it on my Simmons crib instructions page here:

Simmons Crib Replacement Screws and Where They Are Used

When screws are missing from a Simmons crib, they are most often from high-stress connection points. These areas are designed to hold the crib frame securely together, which is why matching the correct size and thread type matters.

Common locations where screws may be missing include:

• Side rail to headboard or footboard connections
• Mattress support frame brackets
• Conversion rail attachment points
• Stabilizer or cross-brace connections

Many Simmons cribs use machine screws that thread into metal inserts or barrel nuts rather than standard wood screws. Using the wrong screw type can prevent the crib from assembling correctly or cause stripped threads.

Can You Replace Simmons Crib Screws Without a Full Hardware Kit?

In some cases, yes. If only one or two screws are missing, parents are sometimes able to replace them individually by matching the length, diameter, and thread type. Measuring an existing screw from the crib can help narrow this down.

However, if multiple screws are missing — or if the crib has been disassembled for a long time — a compatible hardware kit is often the easier option. Kits usually include matching bolts, barrel nuts, and washers designed to work together.

What to Do If You’re Missing Screws and Don’t Know the Model

If the model number label is missing or unreadable, you still have options. Start by taking clear photos of the crib’s connection points, brackets, and any remaining screws. These details can help narrow down the type of hardware used.

You can also compare your crib’s design — such as rail style, slat spacing, and mattress support layout — to known Simmons models shown in manuals and parts diagrams. This often provides enough information to choose compatible replacement screws.

Tips for Matching Simmons Crib Replacement Screws Correctly

When replacing missing Simmons crib screws, taking a few extra minutes to compare hardware details can help prevent ordering mistakes. Pay close attention to screw length, thread thickness, and whether the screw is designed to tighten into a metal insert or a barrel nut. These small differences matter, especially on older crib models.

If you still have one original screw available, bring it with you when shopping locally or use it as a reference when reviewing online listings. Measuring the screw with a ruler or caliper can help confirm length and diameter. Photos of the screw next to a coin or ruler can also be useful when comparing options.

If a replacement screw does not thread smoothly or does not sit flush once tightened, stop and reassess before continuing assembly. Taking time to match the correct hardware helps avoid stripped threads and makes reassembly easier.

Important Notes About Replacement Screws

This page is intended to help you locate compatible replacement screws and hardware for Simmons cribs. It does not replace manufacturer instructions or professional guidance. If you’re unsure whether a replacement screw matches your crib’s original hardware, it’s best to pause assembly until you can confirm compatibility.

For general guidance on crib assembly and hardware expectations, you can also review information provided by the U.S. Consumer Product Safety Commission:

This page provides general information to help parents locate compatible replacement screws and hardware for Simmons cribs. It is not affiliated with or endorsed by the manufacturer. Crib designs, hardware specifications, and safety guidance can vary by model and year. Always refer to the original manufacturer instructions when available, and pause assembly if a part does not appear to match the original hardware.

Using properly sized, correctly threaded screws helps ensure the crib assembles as designed and avoids damage to the frame or hardware inserts.
