Value Collection 39615 1/2-20 Unf Steel Hex Nut

Product Description

The VALUE COLLECTION 39615 is a 1/2-20 UNF steel hex nut with a right-hand thread direction and a zinc yellow dichromate finish. It measures 0.75 inches across the flats and stands 0.4375 inches high. This nut is a standard fastener used to secure bolts, threaded rods, and studs in a wide range of mechanical and structural assemblies. The zinc yellow dichromate coating provides corrosion resistance for applications where exposure to moisture or mild chemicals is a factor. Licensed tradespeople and maintenance technicians working in HVAC, plumbing, electrical, and general mechanical trades will find this nut suitable for everyday fastening tasks.

This hex nut is suited for residential and light commercial maintenance, repair, and assembly work wherever a 1/2-20 UNF fine-thread fastener is required. Fine-thread UNF fasteners are commonly specified when greater thread engagement, higher tensile strength per cross-section, or finer torque adjustment is needed compared to coarse-thread alternatives. The zinc yellow dichromate finish makes this nut appropriate for indoor and semi-protected outdoor environments.

Key Features

• 1/2-20 UNF fine-thread specification for precise thread engagement
• Right-hand thread direction — standard installation orientation
• Steel construction for strength in mechanical fastening applications
• Zinc yellow dichromate finish for corrosion resistance
• 0.75 inches across flats — fits standard 3/4-inch hex wrench or socket
• Compact 0.4375-inch height suits space-constrained assemblies

Compatibility

Designed for use with any 1/2-20 UNF right-hand threaded bolt or stud in mechanical, structural, or equipment assembly applications.

Installation Notes

Installation requires a 3/4-inch open-end wrench, box wrench, or socket driver. Ensure mating bolt threads are clean and free of debris before threading the nut. Hand-tighten first to confirm proper thread engagement and avoid cross-threading. Follow applicable mechanical or equipment manufacturer torque guidelines for the specific assembly.
