Value Collection KP66141 Hex Lock Nut 1/4-28 Grade C 100 Pack

Product Description

The VALUE COLLECTION KP66141 is a distorted-thread hex lock nut designed to maintain clamp load in vibration-prone assemblies. The distorted-thread locking style deforms a portion of the nut thread, creating a prevailing torque that resists back-off without the need for secondary locking hardware. Made from Grade C steel with a zinc-plated and waxed finish, this nut provides corrosion resistance suitable for general industrial and mechanical applications. Thread size is 1/4-28 UNF, right-hand thread, conforming to inch measurement standards. Sold in a package quantity of 100, these nuts are appropriate for use by maintenance technicians, assemblers, and trade professionals working with fine-thread fastener systems.

This hex lock nut is suited for use in light machinery, HVAC equipment frames, electrical enclosures, and general mechanical assemblies where vibration or thermal cycling could loosen a standard nut. The 1/4-28 UNF thread is a fine-pitch designation commonly found in precision assemblies requiring tighter thread engagement. The zinc-plated with wax finish supports mild corrosion resistance in indoor or sheltered environments. Quantity of 100 per package makes this product practical for production runs, service kits, or shop stock replenishment.

Key Features

• Distorted-thread locking style provides prevailing torque to resist loosening from vibration
• 1/4-28 UNF right-hand thread for compatibility with fine-thread fastener applications
• Grade C steel construction for reliable strength in general-duty assemblies
• Zinc-plated with wax finish for corrosion resistance in sheltered environments
• 100 nuts per package suitable for shop stock or production use
• Inch measurement system conforming to UNF fastener standards

Compatibility

Designed as a standard replacement or service-stock hex lock nut for assemblies using 1/4-28 UNF right-hand threaded fasteners in Grade C steel applications.

Installation Notes

Installation is performed by hand-threading the nut onto a 1/4-28 UNF bolt or stud, then torquing to the value specified by the equipment manufacturer for the assembly being serviced. De-energize and lock out all power sources before working on any mechanical or electrical assembly. Distorted-thread lock nuts are single-use by design and should not be reused after removal, as the locking torque diminishes with each installation cycle. Standard hex wrenches or sockets appropriate for the nut width across flats are used for installation.
