It’s very common for assembly kits to go missing on older cribs like your Simmons Baby Madisson 303680-108.

Consider yourself fortunate that you’ve got all the big structural pieces and are just lacking the hardware. Here are some suggestions as to how to handle this situation:

1) What you need are:

Crib-grade screws and bolts sized to the originals that came with the crib

Washers and lock nuts or hex nuts that match the threads

The small pieces that hold rails to headboard/footboard

There isn’t an official replacement kit from Simmons anymore for this model, but you may be able to use a compatible hardware set that matches the original size and strength.

Check the parts diagram that lists screws and bolts that are appropriate for most Simmons sleigh cribs, including Simmons Madisson cribs like yours:



That page shows hardware options that match the common sizes used in Simmons crib assembly.


See available replacement hardware & hardware kits here.



2) What you should do before buying hardware

To make sure you get the right pieces:

Take clear photos of the crib ends where the rails attach

Measure the holes (diameter and spacing) if you can

Note which parts are missing (bolt, washer, nut, etc.)

Even if the original kit is lost, knowing what holes you have now will make it easier to confirm whether the replacement screws/bolts available will actually fit.

3) Why this matters for safety

Crib hardware needs to:

Be strong enough for structural loads

Match the original thread sizes

Use appropriate lock washers or locking nuts so nothing loosens over time

Using random screws from a hardware store can damage the holes or weaken the crib’s integrity, so it’s better to use a crib-specific hardware kit or a set designed for crib assembly.

4) A quick way to buy the right parts

Many people use a hardware kit with:

A variety of crib-grade bolts

Matching nuts & washers

Clear charts of sizes
