Value Collection 52593696-100 Hex Lock Nut 1-8 Grade 8

Product Description

The VALUE COLLECTION 52593696-100 is a Grade 8 steel hex lock nut with a nylon insert, designed for high-strength fastening applications where vibration resistance is required. The nylon insert creates a prevailing-torque locking mechanism that resists loosening under dynamic loads without damaging the mating thread. Finished in yellow zinc dichromate, this nut provides corrosion resistance suitable for general industrial and mechanical environments. It measures 1-3/64 inches in height with a 1-7/16-inch width across flats and is threaded to the UNC 1-8 standard with a right-hand thread direction.

This nut is used across industrial, mechanical, and structural assembly applications wherever a reliable, reusable locking fastener is needed. It is appropriate for use in equipment assembly, machinery maintenance, and general fabrication work where bolt and nut connections are subject to vibration or repeated loading. The UNC 1-8 thread size and Grade 8 material rating make it suitable for heavy-duty fastening in steel-on-steel assemblies.

Key Features

• Nylon insert locking mechanism resists loosening under vibration without thread damage
• Grade 8 steel construction provides high tensile and proof load strength
• Yellow zinc dichromate finish offers corrosion protection for general-duty environments
• UNC 1-8 thread specification with right-hand thread direction
• 1-7/16-inch width across flats fits standard hex tooling

Compatibility

Designed as a standard UNC 1-8 hex lock nut for use with any Grade 8 or equivalent 1-inch UNC-threaded bolt or stud in industrial and mechanical assemblies.

Installation Notes

Installation is performed with standard hex wrenches or sockets sized to 1-7/16 inches across flats. Ensure the mating bolt thread is clean and free of damage before installation to avoid compromising the nylon insert. Because the nylon insert deforms slightly upon first use, reuse of nylon insert lock nuts in critical applications should follow applicable fastener standards and engineering judgment. De-energize or lock out any equipment before servicing fastened assemblies per applicable safety procedures.
