Value Collection R56001394 Hex Jam Nut 1/2-20 Unf

Product Description

The VALUE COLLECTION R56001394 is a 1/2-20 UNF hex jam nut machined from stainless steel with a right-hand thread direction. Jam nuts are thin-profile fasteners used to lock a standard nut in place or to secure a threaded rod, stud, or fitting at a fixed position. This nut measures 0.75 inches across the flats and 0.3125 inches in height, making it a low-profile locking solution. The uncoated stainless steel construction provides corrosion resistance suitable for mechanical assemblies, plumbing connections, and light industrial applications. Technicians and tradespeople working with threaded fastener systems will find this nut compatible with standard 1/2-20 UNF tooling.

This hex jam nut is suited for use in mechanical, plumbing, and general trade assemblies where a 1/2-20 UNF fine-thread fastener is required. The right-hand thread direction follows standard installation practice. The stainless steel material makes it appropriate for environments where mild corrosion resistance is needed, such as exposed mechanical panels, pump assemblies, or outdoor equipment mounting. This nut is supplied individually but requires a minimum order of 10 units.

Key Features

• 1/2-20 UNF fine-thread specification for precise thread engagement
• Stainless steel construction provides corrosion resistance without coating
• Right-hand thread direction follows standard fastener practice
• 0.75 inches across flats — fits standard 3/4-inch hex tooling
• Low-profile at 0.3125 inches height, suited for jam-nut locking applications
• Uncoated finish — no risk of coating degradation in service

Compatibility

Designed as a standard 1/2-20 UNF hex jam nut for use in any mechanical or trade assembly requiring a right-hand fine-thread locking nut of this thread size.

Installation Notes

De-energize and isolate any equipment before servicing threaded fastener assemblies. Use a calibrated 3/4-inch hex wrench or open-end wrench to seat and torque this nut against a mating standard nut or surface. Follow applicable mechanical or plumbing codes for fastener torque requirements specific to the assembly. Avoid cross-threading by hand-starting the nut before applying tool torque.
