Value Collection KP44078 Hex Head Cap Screw 1/2-13 X 1-1/2 in Grade 8

Product Description

The VALUE COLLECTION KP44078 is a fully threaded hex head cap screw designed for high-strength fastening applications. Manufactured from Grade 8 steel with a zinc-plated finish, this fastener meets ASTM A354 BD standards, making it suitable for demanding structural and mechanical connections. The 1/2-13 UNC thread size and 1-1/2-inch length under head provide reliable clamping force in applications where vibration resistance and tensile strength are critical. Each package contains 50 screws. This screw is installed using a standard hex wrench or socket and is intended for use by maintenance technicians, millwrights, pipefitters, and general trade professionals.

This cap screw is well suited for general industrial, mechanical, and construction assembly work. The UNC thread form is the standard for inch-series fasteners used across HVAC equipment mounting, pipe support structures, electrical enclosure hardware, and related trade applications. The zinc plating provides moderate corrosion resistance for indoor and sheltered outdoor environments. Supplied in a package quantity of 50, this screw is a practical stocking fastener for service vans, shop benches, and maintenance departments requiring a high-strength 1/2-13 hex cap screw.
