Description

An insert nut is a fastener with internal and external threading that's used to support a bolt. Insert nuts are also known as threaded inserts or insert bushings. How they work Insert nuts are inserted into a pre-drilled hole. The external threading grips the object, while the internal threading provides stability for the bolt. The external protrusions bite into the wood, preventing the nut from turning or pulling out. Where they're used Woodworking: Insert nuts are used to attach castors, head boards, drawer slides, knobs, and handles. Metalworking: Insert nuts are used to fasten items like handrails to metal buildings. Vehicle assembly: Insert nuts are used to produce powerful threads in thin sheet metal. Aerospace: Insert nuts are used to fasten parts of aircraft. Electronics and telecommunications: Insert nuts are used to mount circuit boards, brackets, and other parts. Types of insert nuts Nutserts: A type of round, thin-wall threaded insert with a low-profile flange. Clear passivated inserts: A type of threaded insert with a protective coating that makes it less reactive to its environment. Galvanized inserts: A type of threaded insert with a protective coating of zinc to prevent oxidation or rust.
