Value Collection KP44043 Hex Head Cap Screw 3/8-16 Grade 8

Product Description

The VALUE COLLECTION KP44043 is a 3/8-16 UNC hex head cap screw designed for high-strength fastening applications across mechanical, structural, and industrial assemblies. Manufactured from Grade 8 steel with a zinc-plated finish, this fastener delivers the tensile strength required for demanding bolted connections. The partial thread design concentrates clamping force through the shank, making it well suited for through-bolt and clamped-joint applications. At 1-3/4 inches in length under the head, it covers a range of standard joint thicknesses. Meets ASTM A354 BD specifications. Sold in a package of 50 pieces.

This hex cap screw is used in maintenance, repair, and fabrication work where a high-strength inch-series fastener is required. Typical applications include equipment mounting, structural bracketing, machinery assembly, and field repair across HVAC, electrical, plumbing, and general mechanical trades. The zinc-plated finish provides baseline corrosion resistance for indoor and moderately protected outdoor environments. The standard hex drive accepts common 9/16-inch wrenches and sockets.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high-strength fastening
• Partial thread shank supports clamped-joint and through-bolt installations
• Zinc-plated finish provides corrosion resistance in protected environments
• 3/8-16 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• 1-3/4 inch length under head suits a variety of joint stack-ups
• Packaged in quantities of 50 for shop stock and field use

Compatibility

Designed for use with standard 3/8-16 UNC inch-series nuts, washers, and tapped holes in Grade 8 or equivalent high-strength fastener assemblies.

Installation Notes

Installation is performed with a standard 9/16-inch combination wrench, box wrench, or socket. Always confirm the mating nut or tapped hole is rated for Grade 8 service before torquing. Do not mix metric and inch fasteners in the same joint. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for 3/8-16 Grade 8 fasteners.
