Value Collection 403182PR Hex Cap Screw 1/2-13 X 1-1/4 in Grade 2

Product Description

The VALUE COLLECTION 403182PR is a fully threaded hex head cap screw designed for general-purpose mechanical fastening applications. Sized at 1/2-13 x 1-1/4 inches with a Unified National Coarse (UNC) thread standard, it delivers dependable clamping force in a wide range of structural and equipment assembly tasks. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener offers basic corrosion resistance suitable for indoor and light-duty outdoor use. A licensed tradesperson, maintenance technician, or mechanical contractor will find this screw appropriate wherever a standard inch-series hex fastener is called for.

This fastener is suited for residential and light commercial applications, including HVAC equipment assembly, electrical enclosure mounting, plumbing fixture brackets, and general mechanical work. The fully threaded shank allows full thread engagement across the entire length under head, making it effective in thinner materials and close-tolerance joints. The 3/4-inch hex key size is compatible with standard open-end, box-end, and socket wrenches common on any service truck.
