What are Knock-down Fasteners? - Handyman

Knock-down fasteners are clever pieces of hardware that are used to make a butt joint, which is the simplest technique to join two members together. The members must be cut to the correct length and butted together at the right angle. The members are glued together and are usually reinforced by several methods. Knock-down fasteners are a common example of a reinforced butt joint.

Typical Use

It’s called “knock-down” because you can simply knock it down however many times to assemble and re-assemble it. If you’ve ever purchased flat-pack furniture, then you have seen and used knock-down fasteners.

When you purchase flat-pack furniture, it comes in individual components that have been pre-cut, pre-drilled, and are meant to be held together by knock-down fasteners.

These fasteners differ from wall anchors, which are used to attach the assembled shelving to a wall. While these fasteners connect and disconnect easily, they do make a pretty strong joint connection. This allows furniture manufacturers to use an inexpensive and weak material, such as a particleboard, and still end up with a stable and strong product.

How Do They Work?
