Value Collection B52001607 Hex Lock Nut 3/4-10 Grade 8

Product Description

The VALUE COLLECTION B52001607 is a 3/4-10 UNC hex lock nut with a nylon insert locking style, manufactured from Grade 8 steel with a zinc yellow dichromate finish. The nylon insert deforms against the bolt threads to create prevailing torque, resisting loosening from vibration and shock loads without requiring a separate lock washer or thread-locking compound. Standing 7/8 inches high with a 1-1/16 inch width across flats and a right-hand thread direction, this nut is sized for standard 3/4-10 UNC fastener applications. It is a common choice in structural, industrial, and heavy equipment assemblies where vibration resistance and corrosion protection are both required.

This hex lock nut is suited for use in mechanical assemblies, fabrication, and maintenance applications that demand reliable thread retention. The zinc yellow dichromate coating provides moderate corrosion resistance, making it appropriate for general industrial environments. It is typically installed by millwrights, maintenance technicians, welders, and general contractors working on equipment frames, structural connections, and machine bases requiring Grade 8 fastener strength.

Key Features

• Nylon insert provides prevailing torque locking without adhesives or additional hardware
• Grade 8 steel construction for high-strength fastener applications
• Zinc yellow dichromate finish for moderate corrosion resistance
• 3/4-10 UNC right-hand thread for compatibility with standard inch-series bolts and studs
• 7/8 inch height and 1-1/16 inch width across flats for use with standard 3/4-inch wrench sizing

Compatibility

Designed for use with 3/4-10 UNC inch-series bolts and threaded studs in Grade 8 fastener assemblies where a nylon insert prevailing-torque lock nut is specified.

Installation Notes

Installation is performed using a standard 1-1/16 inch open-end, box-end, or socket wrench. Power down or de-energize any associated equipment before fastener service. Nylon insert lock nuts are generally rated for single use — once removed, inspect the nylon insert for deformation and replace the nut if locking torque is compromised. Torque to the value specified by the joint designer or applicable engineering standard for Grade 8 fasteners.
