Value Collection KP44020 5/16-18 X 3/4 in Grade 8 Hex Cap Screw 100pk

Product Description

The VALUE COLLECTION KP44020 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and trade assembly work. Manufactured from Grade 8 steel with a zinc-plated finish, this fastener meets ASTM A354 BD specifications, making it suitable for demanding structural and mechanical connections. The 5/16-18 UNC thread pattern and 3/4-inch length under head provide reliable clamping force in standard inch-system assemblies. This package contains 100 screws, making it practical for production runs, service fleets, or shop stock replenishment. Installation is straightforward for any mechanic, millwright, or field technician working with inch-standard hardware.

This fastener is suited for general mechanical assembly, equipment mounting, and structural fastening where high tensile strength is required. The fully threaded shank maximizes thread engagement across the full grip length, which is especially useful in thin-material and short-grip applications. The zinc plating provides a base level of corrosion resistance appropriate for indoor and sheltered outdoor environments. HVAC technicians, plumbers, electricians, and general tradespeople commonly use Grade 8 hardware for equipment mounting brackets, panel attachments, and mechanical connections requiring greater strength than Grade 5 fasteners.

Key Features

• 100-piece package quantity supports shop stock and production-level use

Compatibility

Designed for use with standard 5/16-18 UNC inch-system threaded holes, nuts, and inserts in steel, aluminum, and other common structural materials.

Installation Notes

Install using a standard hex driver or socket wrench sized for a 5/16-inch hex head cap screw. Always verify the mating thread is clean and free of damage before driving. Torque to the appropriate specification for the joint material and Grade 8 fastener class as listed in applicable engineering references or equipment service documentation. Do not mix Grade 8 hardware with lower-grade nuts or threaded inserts not rated for the corresponding load.
