Value Collection CLNFI20310-100BX Hex Lock Nut 5/16-24

Product Description

The VALUE COLLECTION CLNFI20310-100BX is a distorted-thread hex lock nut designed to resist loosening under vibration and dynamic loads. Manufactured from Grade 2 steel with a zinc-plated finish, it uses a mechanically deformed thread profile to create prevailing torque without the need for a nylon insert or secondary locking element. The 5/16-24 UNF thread size and right-hand thread direction make it a standard choice for fine-thread fastening applications. Electricians, HVAC technicians, and mechanical contractors reach for this style of nut when a reliable, reusable lock nut is needed in moderate-duty assemblies.

This nut is suited for use in residential and light commercial mechanical assemblies where vibration resistance is required and temperatures or conditions would compromise a nylon-insert lock nut. Typical applications include equipment panels, bracket mounting, motor and blower assemblies, and general trade-service fastening where a 5/16-24 UNF fine-thread fastener is specified. The zinc plating provides basic corrosion resistance for indoor and protected outdoor installations. Sold in multiples of 100 per order.

Key Features

• Distorted-thread locking style provides prevailing torque without nylon inserts
• 5/16-24 UNF right-hand thread — standard fine-thread specification
• Grade 2 steel construction for moderate-duty fastening
• Zinc-plated finish for basic corrosion resistance
• 17/64 inch height and 1/2 inch width across flats — compact hex profile
• Two-way lock nut design allows installation from either end of the fastener

Compatibility

Designed as a standard UNF 5/16-24 distorted-thread hex lock nut compatible with any 5/16-24 right-hand-thread bolt or stud meeting inch-system fastener specifications.

Installation Notes

Install and tighten using a standard hex wrench or socket sized to 1/2 inch across flats. Power down or de-energize any equipment before accessing fastener locations in electrical or mechanical enclosures. Distorted-thread lock nuts are reusable but prevailing torque diminishes with repeated removal and reinstallation — replace if locking resistance is noticeably reduced. Follow applicable fastener torque guidelines per the equipment manufacturer or relevant mechanical codes.
