Value Collection KP44173-3 Hex Cap Screw Grade 8 5 Pack

Product Description

The VALUE COLLECTION KP44173-3 is a Grade 8 steel hex head cap screw sized at 1-8 x 7-1/2 inches, supplied in a pack of 5. It features a zinc-plated finish for corrosion resistance and partial threading along the shank, which is standard for heavy-duty fastener applications where clamping strength and shear resistance are critical. Conforming to ASTM A354 BD, this fastener meets established strength and material requirements for structural and industrial use. It uses a Unified National Coarse (UNC) thread standard, making it compatible with the widest range of standard nuts and tapped holes in inch-measurement applications.

This screw is suited for mechanical assemblies, equipment fabrication, structural connections, and general industrial fastening where high-strength hardware is required. The 7-1/2 inch length under head accommodates thick material stacks or deep bolt patterns. Partially threaded shanks provide a smooth bearing surface through one or more members, reducing lateral movement and improving joint integrity. Maintenance technicians, millwrights, pipefitters, and general contractors routinely use fasteners of this specification in both commercial and industrial settings.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile and proof load strength
• Zinc-plated finish provides baseline corrosion protection in dry to mildly humid environments
• Partially threaded shank reduces lateral play and improves clamping performance in thick assemblies
• UNC thread standard ensures broad compatibility with standard inch-series nuts and tapped holes
• 1-8 thread size and 7-1/2 inch length under head suit heavy-duty structural and mechanical applications
• Sold in a pack of 5 with a minimum order quantity of 1 pack

Compatibility

Designed for use with standard inch-series Grade 8 hex nuts and hardened washers conforming to UNC thread specifications in structural, mechanical, and industrial fastening applications.

Installation Notes

Installation should be performed by qualified mechanics, millwrights, or tradespeople familiar with torque requirements for Grade 8 fasteners. Always use a hardened flat washer under the head and nut when applicable, and follow engineered torque specifications for the specific joint design. Inspect threads and mating holes for damage or contamination before assembly. Do not substitute Grade 8 fasteners with lower-grade hardware in structural or safety-critical connections.
