Value Collection 403052PR Hex Cap Screw 5/16-18 X 1/2 in Grade 2

Product Description

The VALUE COLLECTION 403052PR is a fully threaded hex head cap screw intended for general-purpose mechanical and structural fastening applications. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener measures 5/16-18 thread size with a 1/2-inch length under the head. The zinc coating provides basic corrosion resistance suitable for indoor and light-duty outdoor use. It follows the Unified National Coarse (UNC) thread standard, making it compatible with standard 5/16-18 tapped holes and nuts. Installers in HVAC, plumbing, and general mechanical trades will find this screw appropriate for panel mounting, bracket attachment, and equipment assembly tasks.

This cap screw is suited for residential and light commercial applications where Grade 2 steel strength meets fastening requirements. Typical uses include securing equipment housings, mounting brackets, and general hardware assembly in trade and maintenance environments. The fully threaded shank allows clamping engagement along the entire fastener length, which is useful in thinner material stacks. Sold individually with a minimum order quantity of 100 pieces per order.
