Value Collection 330430PS Hex Nut 1/2-20 Unf Grade 2 Zinc-plated

Product Description

The VALUE COLLECTION 330430PS is a 1/2-20 UNF hex nut manufactured from Grade 2 steel with a zinc-plated finish. It features a right-hand thread pattern and measures 0.75 inches across the flats with a height of 0.3125 inches. This nut is a standard fastener used across plumbing, HVAC, electrical, and general mechanical assemblies wherever a 1/2-20 fine-thread connection is required. Tradespeople, maintenance technicians, and mechanical contractors reach for this nut when securing components on fine-threaded bolts and studs. The zinc plating provides a baseline level of corrosion resistance suitable for indoor and sheltered outdoor applications.

This hex nut is suited for residential and light commercial applications including equipment mounting, pipe support hardware, panel assembly, and general structural connections that call for a 1/2-20 UNF fine-thread fastener. Grade 2 steel is appropriate for low- to medium-strength clamping applications. It is not rated to military specifications. The 3/4-inch across-flats dimension accepts a standard 3/4-inch wrench or socket, making it compatible with common hand and power tool setups found on any job site.

Key Features

• 1/2-20 UNF fine-thread specification for precise thread engagement
• Grade 2 steel construction for low- to medium-strength fastening applications
• Zinc-plated finish for baseline corrosion resistance
• Right-hand thread direction — standard installation orientation
• 0.75 inches across flats — fits standard 3/4-inch wrenches and sockets
• Does not meet military specifications — for commercial and residential use

Compatibility

Designed for use with any 1/2-20 UNF fine-thread bolt or stud in general mechanical, HVAC, plumbing, and electrical assembly applications.

Installation Notes

Installation requires a 3/4-inch wrench or socket. Ensure mating bolt or stud thread specification matches 1/2-20 UNF before installation. Hand-thread the nut fully before applying tool torque to avoid cross-threading. Power down or de-energize any equipment before accessing fasteners on energized panels or mechanical assemblies.
