Value Collection KP44012 Hex Cap Screw 1/4-20 X 3-1/2 in Grade 8

Product Description

The VALUE COLLECTION KP44012 is a 1/4-20 x 3-1/2 inch hex head cap screw manufactured from Grade 8 steel with a zinc-plated finish. Partially threaded along its shank, this fastener follows UNC thread standards and meets ASTM A354 BD specifications, making it suitable for high-strength bolted connections. The hex head design accepts standard wrenches and sockets for installation and removal. This screw is sold in a package quantity of 50 units, making it a practical choice for contractors, maintenance technicians, and trades professionals who need reliable Grade 8 fasteners on hand for structural and mechanical assembly work.

This fastener is suited for use in mechanical, structural, and industrial assembly applications where high tensile strength and corrosion resistance are required. The zinc-plated finish provides a baseline level of corrosion protection for indoor and light-duty outdoor environments. The partial threading allows the unthreaded shank to bear shear loads in bolted connections, which is a common requirement in equipment mounting, framing hardware, and general mechanical assembly across HVAC, plumbing, and electrical trade installations.

Installation Notes

Installation should be performed by a qualified technician familiar with fastener torque requirements for Grade 8 hardware. Always consult applicable torque specification charts for 1/4-20 Grade 8 fasteners before tightening. Use a properly sized wrench or socket to avoid rounding the hex head. Inspect threads on mating nuts and tapped holes before installation to ensure clean engagement.
