Value Collection MP30114 Hex Cap Screw 1/2-13 X 3-1/2 in Grade 5

Product Description

The VALUE COLLECTION MP30114 is a 1/2-13 x 3-1/2 inch hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. Partially threaded along the shank, this fastener meets ASME B18.2.1 dimensional standards for inch-series hex cap screws. The 1/2-13 designation indicates a 1/2-inch nominal diameter with 13 threads per inch on a Unified National Coarse (UNC) thread form. The zinc plating provides baseline corrosion resistance suitable for general indoor and moderate outdoor applications. This screw is a standard trade fastener installed by millwrights, pipefitters, HVAC technicians, electricians, and general mechanical contractors wherever a reliable, code-referenced hex cap screw is required.

This fastener is suited for structural and mechanical assembly applications across residential, commercial, and light industrial environments. Common install scenarios include equipment mounting, bracket fabrication, ductwork supports, pipe hanger assemblies, and general structural connections. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for applications where a full-thread screw would be less effective. Sold in a package quantity of 10.

Key Features

• 1/2-13 UNC thread form — widely compatible with standard hex nuts and tapped holes in inch-series hardware
• 3-1/2 inch length under head — partially threaded shank provides shear-bearing capability
• Grade 5 steel construction — meets medium-strength fastener requirements for structural and mechanical use
• Zinc-plated finish — baseline corrosion protection for general service environments
• Meets ASME B18.2.1 dimensional standard for hex cap screws
• Sold in a 10-piece package with a minimum order quantity of 1

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, flat washers, and lock washers in inch-series mechanical and structural assemblies.

Installation Notes

Installation should be performed by a qualified mechanic, technician, or tradesperson familiar with fastener torque requirements for Grade 5 hardware. Always use the correct hex wrench or socket to avoid rounding the head. Verify that mating threads and tapped holes are clean and free of debris before installation. Do not exceed the rated proof load for Grade 5 fasteners; consult applicable mechanical or structural codes for torque specifications relevant to your application.
