The VALUE COLLECTION CLNI20620-050BX is a distorted-thread hex lock nut designed to resist loosening under vibration and dynamic loads. It carries a 5/8-11 UNC thread size with a right-hand thread direction and is manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. Standing 35/64 inches high with a width across flats of 15/16 inches, this two-way lock nut installs quickly using standard hex tooling. It is suited for general mechanical assemblies, structural fastening applications, and maintenance work where a low-profile locking fastener is required.
This nut is appropriate for use in residential, commercial, and light industrial settings wherever a 5/8-11 UNC threaded fastener needs a reliable locking element. Typical applications include equipment mounting, structural steel connections, HVAC unit bases, pump and motor mounting plates, and general fabrication work. The distorted-thread locking mechanism does not require a secondary locking device such as a split washer or thread-locking adhesive, making it a practical choice for high-volume assembly or field service repairs.
Designed as a general-purpose replacement or stock hex lock nut for any 5/8-11 UNC threaded bolt or stud application requiring a distorted-thread locking element in inch-measurement assemblies.
Installation is performed by maintenance technicians, millwrights, or field service personnel using standard open-end, box-end, or socket wrenches sized for a 15/16-inch hex. Ensure mating bolt threads are clean and free of damage before installation. Distorted-thread lock nuts are designed for single-use service in critical joints; do not reuse a previously installed nut where the locking interference may be compromised. Follow applicable torque specifications from the equipment manufacturer or relevant fastener standards for the joint being assembled.
