Crib Hardware Identification Guide: Bolts, Nuts, Brackets and Pins

Crib hardware identification reference helps explain the different names used for bolts, nuts, pins, brackets, spacers, and other small crib parts. This visual guide shows common hardware names and features so you can compare a loose piece with the parts list for the exact crib brand and model.

Crib hardware identification chart

The numbered chart above shows ten common crib hardware groups. These are general names. The exact name used by a crib manufacturer may be different.

1. Machine or connector bolt: A blunt-ended bolt with even machine threads. It often has an Allen, hex, Phillips, or Torx drive.
2. Wood screw: A pointed screw with deeper threads made to enter wood.
3. Barrel nut: A small metal cylinder with a threaded opening through the side. It may also be called a cross dowel.
4. Cam lock and cam bolt: A round locking disk that turns and grips a matching cam bolt or stud.
5. Washer: A flat or split metal ring placed under a bolt head, screw head, or nut.
6. Spacer or bushing: A short sleeve or collar that keeps space between two connected pieces.
7. Connector pin: A smooth or lightly grooved metal pin used to line up or support parts.
8. Retaining clip: A small clip that helps keep a pin, rod, or support piece in place.
9. Bracket or plate: A shaped metal piece with holes or slots used at a connection point.
10. Mattress support hook: A bent or stamped metal piece connected with the mattress support or spring frame.

When a hook, bracket or hanger belongs to the assembly beneath the mattress, the crib mattress support hook and hanger reference explains how these parts relate to spring frames, platforms and model-specific mounting points.

Common crib hardware names and alternate names

A crib manual may use a different name from the one used in a hardware store or another manufacturer’s manual. This table shows common and related terms. Some terms describe different shapes within the same general hardware group, so the manual for the exact crib model remains the final reference.

How manufacturers label hardware in crib manuals

Manufacturers may organize and name similar hardware in different ways. These official product pages include links to model-specific instruction manuals that you can use as naming examples.

• Babyletto Hudson 3-in-1 Convertible Crib instruction manual page
• Graco Benton 5-in-1 Convertible Crib instruction manual page
• DaVinci Kalani 4-in-1 Convertible Crib instruction manual page

These manuals are examples of manufacturer terminology only. A hardware name or drawing from one manual does not identify a part for a different crib.

How crib bolt and screw measurements are described

These measurement terms may appear in a crib parts list, manual, or manufacturer message.

For general fastener names and measurement terms, see this fastener naming and measurement reference.

Photograph checklist for a loose crib hardware piece

Use a simple, matching set of photos so the shape and measurements are easy to compare with a parts diagram.

• Full view: Photograph the complete piece on plain white paper.
• Side view: Show the shape of the shaft, threads, bends, or raised sections.
• Head or opening: Take a close-up of the Allen, Phillips, Torx, slot, hole, or clip shape.
• Measurement view: Place the part beside a ruler without covering either end.
• Markings: Photograph any stamped letters, numbers, grooves, arrows, or other marks.

A photograph can help identify the general hardware category, but the exact crib manual is still needed to confirm the manufacturer’s part name.

What this hardware guide cannot confirm

A photograph, name, or measurement can help identify the general hardware type, but it cannot prove that a part belongs to a certain crib. The manual and parts list for the exact crib model remain the final sources.

When the original manufacturer part cannot be found, see what to do if you cannot find crib replacement parts.

Crib hardware identification questions

What is another name for a crib barrel nut?

A barrel nut may also be called a cross dowel, cross nut, or cylindrical nut. The name used in the crib manual may vary.

What is the difference between a crib bolt and a wood screw?

A crib bolt usually has machine threads and a blunt tip. A wood screw usually has deeper threads and a pointed tip. The exact part must still match the model manual.

What is a crib hardware spacer?

A spacer is a short sleeve or collar that keeps a set distance between two parts. Some manuals call it a bushing, sleeve, collar, or standoff.

Can a photo prove that hardware fits a crib?

No. A photo can help identify the general type, but it cannot confirm fit or compatibility. The exact crib manual and manufacturer parts list are the final sources.

Why do crib manuals use different hardware names?

Manufacturers may use their own parts names. One manual may say barrel nut while another says cross dowel for the same general hardware category.
