Value Collection KP44173-1 Hex Cap Screw Grade 8 Zinc 5 Pack

Product Description

The VALUE COLLECTION KP44173-1 is a Grade 8 steel hex head cap screw sized at 1-8 thread x 6.5 inches under the head, supplied in a pack of 5. It features a zinc-plated finish for corrosion resistance and is partially threaded with a UNC thread standard. Manufactured to ASTM A354 BD specifications, this fastener meets the mechanical property requirements for high-strength bolting applications. It is suited for use by millwrights, pipefitters, ironworkers, electricians, and other trade professionals who require a reliable, standardized heavy-duty fastener in inch-system assemblies.

This screw is intended for structural and mechanical fastening applications where Grade 8 tensile strength and ASTM A354 BD compliance are specified. The partial threading allows for a smooth shank section that carries shear loads across joint interfaces, making it appropriate for flanged connections, equipment mounting, structural steel work, and machinery assembly in both commercial and industrial settings.

Key Features

• Grade 8 steel construction meets ASTM A354 BD mechanical property requirements
• Zinc-plated finish provides baseline corrosion protection
• Partially threaded shank allows shear load transfer across joint interfaces
• UNC thread standard ensures broad compatibility with standard inch-system nuts and tapped holes
• 1-8 thread size x 6.5 inches under the head for deep-reach fastening applications
• Sold in a pack of 5 with a minimum order quantity of 1 pack

Compatibility

Designed for use with standard UNC inch-system nuts and tapped holes requiring a 1-8 thread pitch and Grade 8 or equivalent high-strength fastener specification.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with structural or mechanical fastening requirements. Always de-energize and lock out equipment before working on fastened assemblies. Use calibrated torque tools and follow the applicable torque specifications published by the equipment manufacturer or referenced structural standard for Grade 8 fasteners. Inspect threads and mating hardware for damage before assembly to ensure full load-rated engagement.
