Value Collection B52001661 Hex Lock Nut 1-1/4-12

Product Description

The VALUE COLLECTION B52001661 is a hex lock nut with a nylon insert, designed to resist loosening under vibration and dynamic loads. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener features a 1-1/4-12 UNF right-hand thread and measures 47/64 inches in height with a 1-13/16 inch width across flats. The nylon insert creates interference against the mating thread, providing a secure mechanical lock without requiring thread-locking compounds. Maintenance technicians, pipefitters, and mechanical contractors use this type of fastener across a wide range of structural and mechanical assembly applications.

This hex lock nut is suited for inch-measurement fastener assemblies requiring a reliable, reusable locking solution. The 1-1/4-12 UNF thread designation indicates a fine-pitch thread, commonly found in applications where precise tension adjustment and vibration resistance are critical. The zinc plating provides basic corrosion protection appropriate for indoor and sheltered outdoor environments. Typical use cases include mechanical equipment mounting, structural steel assemblies, and general industrial maintenance work.

Key Features

• Nylon insert locking style resists loosening from vibration without adhesives
• Grade 2 steel construction for standard-duty fastener applications
• Zinc-plated finish provides basic corrosion resistance
• 1-1/4-12 UNF fine-pitch right-hand thread for precise load control
• Standard hex geometry fits common wrenches and sockets

Compatibility

Designed as a standard UNF inch-series hex lock nut compatible with 1-1/4-12 right-hand threaded fastener assemblies in general mechanical and structural applications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel using appropriately sized open-end or box wrenches. Ensure mating threads are clean and free of debris before assembly. The nylon insert is designed for a finite number of installation cycles; inspect the insert for wear if reusing the nut. Do not exceed the torque rating appropriate for Grade 2 steel fasteners of this thread size as specified by applicable engineering or maintenance standards.
