Value Collection 30013 Hex Head Cap Screw 1/4-20 X 3-1/4 in 50pk

Product Description

The VALUE COLLECTION 30013 is a 1/4-20 UNC hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. The fastener measures 3-1/4 inches under the head and is partially threaded, conforming to ASME B18.2.1 dimensional standards. It is designed for general mechanical assembly applications where a reliable bolted joint is required. Licensed contractors, maintenance technicians, and trade professionals install these fasteners in equipment frames, brackets, panel assemblies, and structural mechanical connections across HVAC, electrical, and plumbing trade work.

This screw is suited for light-to-medium duty fastening applications in both residential and commercial settings. The 1/4-20 UNC thread pattern is one of the most common inch-series thread sizes in trade work, making this fastener a practical stock item for service vans, job-site kits, and shop inventory. The partial threading on the shank allows for clamping force between joined materials without thread engagement throughout the full grip length. Each package contains 50 pieces.

Installation Notes

Install using a standard hex wrench, socket, or open-end wrench sized for a 1/4-inch hex head cap screw. Ensure the mating tapped hole or nut is clean and free of debris before installation. Do not exceed the rated torque range for Grade 5 hardware as specified in applicable mechanical codes or equipment service manuals. Zinc-plated fasteners are not rated for outdoor immersion or highly corrosive environments — verify finish suitability before use.
