Value Collection 403062PR Hex Head Cap Screw 5/16-18x1-1/4

Product Description

The VALUE COLLECTION 403062PR is a fully threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and maintenance applications. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener measures 5/16-18 thread size with a 1-1/4 inch length under head. The zinc coating provides basic corrosion resistance suitable for indoor and light-duty outdoor use. The UNC (Unified National Coarse) thread form makes it compatible with standard tapped holes and nuts. A 1/2 inch hex key size allows installation with standard wrenches or sockets. Installed by mechanics, maintenance technicians, and tradespeople across a wide range of industries.

This screw is suited for light to medium-duty fastening tasks in fabrication, equipment assembly, and facility maintenance. The fully threaded shank provides maximum thread engagement across the full grip length, making it well suited for shallow clearance holes and applications where clamping load must be distributed along the entire fastener length. Typical uses include panel mounting, brackets, fixtures, and general equipment repair where Grade 2 steel strength is sufficient.

Installation Notes

Install with a standard 1/2 inch open-end, box, or socket wrench. Verify the mating thread is clean and free of debris before installation to avoid cross-threading. Do not exceed the load ratings appropriate for Grade 2 steel in structural or high-vibration applications where Grade 5 or Grade 8 may be required. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
