Value Collection R50000111 Hex Lock Nut 1/4 in Unc

Product Description

The VALUE COLLECTION R50000111 is a hex lock nut with a nylon insert locking mechanism, manufactured from Grade 2 steel with a zinc-plated finish. The nylon insert creates friction against the mating fastener threads to resist loosening from vibration and torque. This nut measures 5/32 inches in height with a 1/4 inch width across flats and is machined to Unified National Coarse (UNC) inch-standard threading with a right-hand thread direction. It is suited for general mechanical and structural fastening applications where secure thread locking is required without the use of adhesive thread lockers.

This nut is used in residential, commercial, and light industrial assembly applications where vibration resistance is a priority. Typical installation scenarios include equipment enclosures, brackets, frames, and mechanical assemblies across HVAC, plumbing, electrical, and general trade construction. Its zinc-plated finish provides basic corrosion resistance in dry or mildly humid indoor environments. The nylon insert style is a common OEM and field-replacement standard across a wide range of bolted connections requiring UNC inch fasteners.

Key Features

• Nylon insert locking style resists loosening under vibration without adhesives
• Grade 2 steel construction for general-purpose fastening strength

• Compact profile: 5/32 inches height, 1/4 inches width across flats

Compatibility

Designed as a general-purpose UNC inch-standard hex lock nut compatible with Grade 2 bolts and threaded rod in typical mechanical and structural fastening applications.

Installation Notes

Installation requires a standard hex wrench or socket sized to the 1/4 inch width across flats. Power down or de-energize any equipment before servicing fastened assemblies. The nylon insert is single-use by design — once fully torqued and removed, the insert may not provide full locking retention if reused. Follow applicable mechanical codes and manufacturer torque guidelines for the specific assembly being serviced.
