Value Collection 88548474 Hex Head Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 88548474 is a partially threaded hex head cap screw sized at 1/2-13 x 2-1/2 inches, manufactured from Grade 5 steel with a zinc-plated finish. The 1/2-13 designation indicates a 1/2-inch nominal diameter with 13 threads per inch on a UNC thread standard. Partial threading leaves a smooth shank below the head, which is common in applications requiring a clamp load without thread engagement through the full grip length. This fastener is installed by mechanics, millwrights, HVAC technicians, plumbers, and electricians whenever a medium-strength hex cap screw is called for in structural or equipment assembly work.

This screw is suited for general-purpose fastening in residential and commercial applications including equipment mounting, mechanical assemblies, structural connections, and fixture installation. The zinc plating provides a baseline level of corrosion resistance appropriate for indoor and protected outdoor environments. The UNC thread form is the standard for inch-series fasteners across North American trade work, making this screw compatible with standard taps, nuts, and threaded inserts in that size class.

Key Features

• Grade 5 steel construction provides medium strength suitable for most mechanical and structural fastening tasks
• Zinc-plated finish offers corrosion resistance for indoor and protected-environment use
• Partially threaded shank allows full bearing load across unthreaded grip length
• UNC thread standard ensures compatibility with standard inch-series nuts and tapped holes
• 1/2-13 thread size is one of the most common heavy-duty fastener sizes in North American trade work

Compatibility

Designed as a standard UNC inch-series hex head cap screw for use with any 1/2-13 threaded nut, insert, or tapped hole requiring a Grade 5 partially threaded fastener.

Installation Notes

Install using a standard 3/4-inch wrench or socket driver appropriate for a 1/2-13 hex cap screw. Ensure mating threads are clean and free of debris before assembly. De-energize and lock out any equipment before replacing or installing fasteners in electrical, HVAC, or mechanical systems per applicable OSHA lockout/tagout procedures. Do not substitute this Grade 5 fastener in applications specifying Grade 8 or metric property class equivalents without engineering review.
