Value Collection R52001682 Hex Lock Nut 1/4-28 Grade 8

Product Description

The VALUE COLLECTION R52001682 is a 1/4-28 hex lock nut with a nylon insert locking mechanism, manufactured from Grade 8 steel with a zinc yellow dichromate finish. The nylon insert creates prevailing torque resistance that prevents loosening due to vibration or dynamic loads, making it well-suited for high-stress mechanical assemblies. At 19/64 inches in height with a 7/16-inch width across flats, this nut conforms to UNF (Unified National Fine) thread standards and accepts a right-hand thread engagement. Maintenance technicians, millwrights, and general assembly professionals commonly install this fastener across a wide range of structural and mechanical applications.

This hex lock nut is used in applications where vibration resistance is a priority, including equipment frames, machinery mounts, brackets, and general mechanical assemblies requiring a secure, reusable fastener. The Grade 8 steel construction provides high tensile strength, and the zinc yellow dichromate coating offers corrosion resistance in moderately harsh environments. The nylon insert allows for repeated installation and removal while maintaining locking performance over multiple service cycles.

Key Features

• Nylon insert locking style provides reliable prevailing torque resistance without deforming the mating thread
• Grade 8 steel construction delivers high tensile and proof load strength for demanding mechanical assemblies
• Zinc yellow dichromate finish provides corrosion protection in moderately corrosive environments
• 1/4-28 UNF right-hand thread for compatibility with fine-thread fastener systems
• 19/64-inch height and 7/16-inch width across flats conform to standard hex nut tooling

Compatibility

Designed as a standard UNF-thread hex lock nut for use with 1/4-28 right-hand threaded fastener assemblies in inch-measurement mechanical systems.

Installation Notes

Install using a standard 7/16-inch wrench or socket. Ensure mating bolt threads are clean and free of damage before engagement to avoid compromising the nylon insert. Power down or de-energize any equipment before accessing fastener locations in electrical or mechanical enclosures. Do not substitute this nut in applications requiring military-specification fasteners, as this part does not meet military specifications.
