Clamping Fasteners

Collar Nuts

Collar nuts integrate a threaded hexagonal body with an enlarged flanged base to function as a unified fastener and load-distributing washer. This augmented surface area minimizes localized compressive stress on the mating material and significantly increases resistance to vibrational loosening. Forged from high-strength steel alloys, they are widely applied in automotive chassis assembly, structural steelwork, and heavy mechanical engineering where dynamic loading is prevalent.
