The VALUE COLLECTION B10019 is a 7/8-9 UNC Grade G hex flange lock nut with a distorted thread locking mechanism, manufactured from steel with an uncoated finish. The integrated flange distributes clamping load across a wider bearing surface, reducing the need for a separate washer. Distorted thread locking provides resistance to vibration-induced loosening without the use of adhesives or secondary hardware. This fastener is suited for general mechanical assembly, structural connections, and equipment maintenance applications where a reliable, reusable locking nut is required.
This hex flange lock nut is used across a broad range of trade and industrial applications including HVAC equipment assembly, plumbing fixture mounting, electrical panel fabrication, and general mechanical assembly. The 7/8-9 UNC thread specification makes it compatible with standard inch-series threaded fastener systems. The distorted thread design allows the nut to be removed and reinstalled while still retaining meaningful prevailing torque, making it practical for service and maintenance scenarios.
Designed as a standard replacement or new-installation hex flange lock nut for any application using 7/8-9 UNC inch-series threaded fasteners in mechanical, structural, or equipment assembly contexts.
Installation is performed by maintenance technicians, millwrights, or trade professionals using standard hex wrenches or sockets sized for a 7/8-9 UNC hex flange nut. Ensure mating threads are clean and free of debris before installation. Distorted thread nuts provide prevailing torque upon engagement; do not force the nut onto damaged or cross-threaded studs. Fastener torque should follow applicable engineering specifications or equipment manufacturer guidelines for the assembly.
