Value Collection B52001641 Hex Lock Nut 3/4-10 Grade 8

Product Description

The VALUE COLLECTION B52001641 is a 3/4-10 UNC hex lock nut with a nylon insert locking mechanism, manufactured from Grade 8 steel with a yellow zinc finish. The nylon insert creates prevailing torque that resists loosening under vibration and dynamic loads, making this fastener suitable for structural, mechanical, and equipment assembly applications. It measures 0.875 inches in height with a 1.0625-inch width across flats and carries a right-hand thread direction. Licensed mechanics, millwrights, pipefitters, and general contractors routinely specify Grade 8 nylon insert lock nuts where joint integrity under load cycling is required.

This lock nut is suited for heavy-duty bolted connections in industrial machinery, agricultural equipment, automotive assemblies, and structural steel fabrication. The 3/4-10 UNC thread size is a common coarse-thread specification found across a wide range of commercial and industrial fastener applications. The yellow zinc finish provides a baseline level of corrosion resistance for indoor and sheltered outdoor installations.

Key Features

• Nylon insert locking style provides reliable prevailing torque without secondary locking hardware
• Grade 8 steel construction for high-strength bolted joint applications
• Yellow zinc finish offers corrosion resistance for general-purpose use
• 3/4-10 UNC right-hand thread for broad compatibility with standard coarse-thread fastener systems
• 0.875-inch height and 1.0625-inch width across flats match standard hex nut tooling

Compatibility

Designed as a standard UNC coarse-thread hex lock nut compatible with 3/4-10 threaded bolts and studs used in general industrial and mechanical assembly applications.

Installation Notes

Installation is performed using a standard open-end, box-end, or socket wrench sized to 1.0625 inches across flats. Power down or de-energize any equipment before servicing fastened assemblies. Do not reuse nylon insert lock nuts in critical load-bearing joints, as the nylon insert loses prevailing torque effectiveness after removal. Fastener installations on structural or pressure-bearing assemblies should comply with applicable ASME, AISC, or equipment manufacturer torque specifications.
