Value Collection MPKP44040 Hex Cap Screw 3/8-16 X 1 in Grade 8 25pk

Product Description

The VALUE COLLECTION MPKP44040 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, structural, and equipment assembly work. Manufactured from Grade 8 steel with a zinc-plated finish, this fastener meets ASTM A354 BD standards for tensile and proof load strength. The 3/8-16 UNC thread pattern and 1-inch length under head make it a common choice for general industrial and trade installations where a reliable, high-grade fastener is required. Sold in packs of 25, this screw is appropriate for mechanics, millwrights, HVAC technicians, and maintenance trades working with inch-standard hardware.

This cap screw is suited for applications requiring a high-strength fastener in carbon steel assemblies, equipment mounts, structural brackets, and mechanical connections where Grade 8 strength and corrosion resistance from the zinc-plated coating are specified. The fully threaded shank allows engagement along the entire 1-inch length, providing maximum thread engagement in thinner materials or threaded through-holes. Typical applications include equipment frames, motor mounts, condenser brackets, and general mechanical assemblies using 3/8-16 UNC tapped holes or hex nuts.

Key Features

• Grade 8 steel construction meets ASTM A354 BD tensile and proof load requirements
• Zinc-plated finish provides corrosion resistance for general indoor and protected outdoor use
• Fully threaded shank for maximum thread engagement along the full 1-inch length
• 3/8-16 UNC thread standard for compatibility with standard inch-series nuts and tapped holes
• Sold in a pack of 25 for job lot or shop stock replenishment

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts, washers, and tapped holes in inch-series mechanical and structural assemblies.

Installation Notes

Installation requires a 9/16-inch hex socket or wrench for standard 3/8-inch hex head fasteners. Always confirm thread engagement depth meets the fastener and joint design requirements before final torque. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly being serviced. Do not mix Grade 8 fasteners with lower-grade nuts or mismatched thread standards.
