Value Collection KP44046 Hex Head Cap Screw 3/8-16 X 2-1/2 in Grade 8

Product Description

The VALUE COLLECTION KP44046 is a Grade 8 steel hex head cap screw with a 3/8-16 UNC thread and a 2.5-inch length under head. It features a zinc-plated finish for corrosion resistance and is partially threaded, making it suited for clamping and fastening applications where the shank must bear shear loads. Grade 8 designation indicates a high-strength fastener meeting ASTM A354 BD standards. This item is sold in a pack of 50 and is used by mechanical contractors, millwrights, HVAC technicians, plumbers, and general tradespeople working with structural or equipment-mounting assemblies.

This screw is appropriate for use in mechanical, industrial, and trade applications requiring a high-strength inch-series fastener. The 3/8-16 UNC thread is one of the most common coarse-thread sizes in North American trade work and is found in equipment frames, brackets, flanges, and machinery mounting hardware. The partial threading leaves a smooth shank below the head, which distributes shear forces across the grip length rather than relying on the threaded portion alone. Each pack contains 50 pieces, suited for both service calls and larger installation jobs.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high-strength fastener applications
• 3/8-16 UNC coarse thread — widely compatible with standard inch-series nuts and tapped holes
• Partial threading provides a smooth shank for shear load distribution
• Zinc-plated finish offers basic corrosion resistance in dry and mildly humid environments
• Hex head drive accepts standard 9/16-inch wrenches and sockets
• Sold in a 50-piece pack with a minimum order quantity of 1 pack

Compatibility

Designed for use in any application requiring a 3/8-16 UNC hex head cap screw with a 2.5-inch length under head and Grade 8 strength rating, including equipment mounting, bracket fastening, and structural assembly in trade and industrial settings.

Installation Notes

Install using a 9/16-inch combination wrench, box wrench, or socket drive. Ensure the mating nut or tapped hole is also rated for Grade 8 or higher to realize the full clamping strength of this fastener. De-energize or shut down any equipment before servicing fasteners on live assemblies. Do not reuse fasteners that show thread damage, corrosion, or deformation.
