Liberty Engineering has been supplying fasteners to the aerospace, military and commercial markets for over 70 years. Liberty Engineering distributes primarily two types of fasteners: Rivet Nuts or Rivnuts® and Self Locking Nuts.

Rivnuts® or Rivet Nuts are internally threaded blind tubular fasteners. They provide a blind installation into sheet metal, plastic, fiberglass and tubular materials. Rivnuts® perform as a rivet to bind two or more materials together and as a nut for attaching a mating part with a screw into its internal threads. Rivet Nut is the generic term for this type of fastener. Rivnut® is a trade name for rivet nuts manufactured by Bollhoff. Liberty Engineering is an authorized distributor for Bollhoff and Sherex.

A Self-Locking Nut is a internally threaded nut with crimped upper threads or a nylon insert that increases the resistance to loosening by vibration. The self-locking nut product offering includes Anchor Nuts, Clip Nuts, Gang Channels, Rivetless Nut Plates, Standoff Brackets and Wrenchable Nuts. Liberty Engineering is an authorized distributor for Howmet.
