Value Collection R63084485 Hex Jam Nut 1/4-20 Unc

Product Description

The VALUE COLLECTION R63084485 is a 1/4-20 UNC hex jam nut manufactured from stainless steel with a right-hand thread direction. Hex jam nuts are thin profile nuts used to lock a standard nut in place, preventing loosening caused by vibration or torque. The uncoated stainless steel construction provides corrosion resistance suitable for wet, outdoor, or chemically exposed environments. This nut measures 7/16 inches across flats and 5/32 inches in height, conforming to standard UNC dimensional specifications. It is installed by plumbers, HVAC technicians, electricians, and general trade mechanics wherever a secure, low-profile locking fastener is required.

Hex jam nuts of this size are used across a wide range of trade applications including pipe fitting assemblies, equipment mounting, electrical enclosure hardware, and mechanical component lockdown. The 1/4-20 UNC thread is one of the most common unified coarse thread sizes in North American mechanical and trade work. This nut is appropriate for both indoor and outdoor installations where corrosion resistance is a factor and a low-profile locking solution is needed.

Key Features

• 1/4-20 UNC right-hand thread for compatibility with standard unified coarse thread fasteners
• Stainless steel construction provides corrosion resistance without a coating
• Low-profile jam nut design at 5/32 inches high for space-constrained applications
• 7/16 inches across flats for use with standard hex wrench or open-end wrench tooling
• Uncoated finish — no plating to chip, flake, or introduce galvanic concerns with stainless assemblies

Compatibility

Designed for use with 1/4-20 UNC threaded fasteners and hardware following unified coarse thread standards. Suitable as a jam locknut in any assembly requiring a 1/4-20 UNC thread engagement.

Installation Notes

Install using a standard 7/16 inches open-end or box wrench. Thread the jam nut onto the stud or bolt first, then thread the primary nut on top and torque to the assembly specification before back-tightening the jam nut against it to lock the assembly. Ensure both mating threads are clean and free of debris before installation. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound if required by the application.
