Universal Headboard/Footboard Hardware Set - 8pcs 4 & 2.5 Bolts for Furniture, Beds, Cots, Cribs, Chairs - Round Head Square Neck Carriage Bolt

A carriage bolt, also known as a coach bolt or round head square neck bolt, is a type of bolt specifically designed to fasten metal to wood, such as a headboard or footboard. What sets a carriage bolt apart from other bolts is its unique shallow mushroom head and square neck just beneath the head. This square neck design allows the bolt to be self-locking when inserted through a square hole in a metal strap, requiring only a spanner or wrench for installation from one side.

The head of a carriage bolt typically features a shallow dome, and the shank of the bolt is completely smooth without any threads. The diameter of the shank matches the side length of the square cross-section, making it ideal for securing timber without causing rotation. Carriage bolts are commonly used in security applications, such as locks and hinges, where the bolt needs to be removable from only one side.

Our high-quality barrel bolt nuts kit is perfect for repairs and replacements. The set includes barrel bolts nuts that can be used for a variety of items including beds, chairs, cots, cribs, sofas, and other types of furniture. They are also great for joining wood, boards, kitchen worktops, and more.

Our package is designed to accommodate most headboards and footboards, regardless of thickness. We provide four 2½" bolts for thinner headboards and four 4" bolts for thicker headboards, along with eight nuts and washers.

Made from durable 304 stainless steel, our carriage bolts offer superior strength and corrosion resistance, making them suitable for use in various environments, including high temperatures, cold weather, and high humidity areas. They are rust-resistant and have excellent oxidation resistance for long-lasting use.

If you need to connect both a headboard and footboard, you will need to purchase two universal sets packs. The nuts and flat washers included in the kit help expand the contact area and reduce pressure to protect the screws and parts. The compact and uniformly threaded screws are resistant to deformation during installation.
