Value Collection MPKP44078 Hex Cap Screw 1/2-13 X 1-1/2 in Grade 8

Product Description

The VALUE COLLECTION MPKP44078 is a fully threaded hex head cap screw designed for high-strength fastening applications across mechanical, structural, and industrial assembly work. Manufactured from Grade 8 steel with a zinc-plated finish, this fastener meets ASTM A354 BD standards, making it suitable for demanding load-bearing connections. The 1/2-13 UNC thread size and 1-1/2 inch length under head provide reliable grip depth for standard structural joints. Sold in packages of 25, this screw is a practical bench stock item for maintenance shops, fabrication operations, and field service work where Grade 8 fasteners are specified.

This cap screw is used in residential and commercial construction, equipment assembly, and general mechanical maintenance wherever high-tensile hex fasteners are required. The fully threaded shank allows engagement along the full length of the fastener, making it well-suited for through-bolt applications and thin-material clamping. The zinc-plated finish provides a base level of corrosion resistance for indoor and light-duty outdoor installations. Installers working in HVAC equipment mounting, plumbing support brackets, and electrical panel framing will find this a common specification fastener.
