McFarlane AN316-4R Jam Nut (100 pcs. Pack) is an aircraft-grade hardware fastener component designed to secure threaded assemblies by providing a low-profile locking interface. Manufactured to AN316 specifications, this jam nut is commonly used in aviation applications where precise adjustment retention and reliable thread engagement are required.

The AN316-4R features 1/4-28 UNF right-hand threads and is designed to lock against a mating threaded component, preventing unintended movement caused by vibration or operational loads. Its thin hexagonal profile allows installation in confined areas where standard-height nuts may not be suitable.

Constructed from high-strength steel with a corrosion-resistant cadmium finish, the jam nut provides durability, reliable thread performance, and protection against environmental exposure. It is commonly used in aircraft control systems, rod ends, linkages, and other adjustable mechanical assemblies requiring secure positioning of threaded components.

This product is supplied as a 100-piece pack, making it suitable for aircraft maintenance operations, repair stations, and inventory stocking. During installation and inspection, the nut should be checked for proper thread engagement, corrosion, deformation, and secure locking function to maintain continued airworthiness.
