Value Collection R52001100 Hex Head Cap Screw Grade 5

Product Description

The VALUE COLLECTION R52001100 is a partially threaded hex head cap screw designed for heavy-duty fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener measures 1-1/2 - 6 thread size with a 5-inch length under head, conforming to ASME B18.2.1 and SAE J429 standards. The zinc plating provides baseline corrosion resistance suitable for general indoor and light outdoor environments. Weighing 3.4 pounds, this is a large-format fastener intended for high-load connections. It is installed by machinists, millwrights, maintenance technicians, and mechanical contractors working on equipment frames, structural steel, and heavy machinery.

This hex head cap screw is suited for industrial and commercial applications requiring a UNC-threaded fastener in the 1-1/2 - 6 thread pitch range. Partial threading is standard on longer fasteners of this diameter, allowing the unthreaded shank to bear shear loads while the threaded section engages the nut or tapped hole. Typical use cases include equipment mounting, conveyor frames, structural bolting, and machinery assembly where Grade 5 tensile and yield strength ratings are specified by the engineer of record or equipment OEM.

Key Features

• Grade 5 steel construction meets SAE J429 mechanical property requirements for medium-strength fastening
• Partially threaded shank handles shear loads alongside tensile clamping force
• Zinc-plated finish provides corrosion resistance for general-duty environments
• UNC thread form (1-1/2 - 6) conforms to ASME B18.2.1 dimensional standards
• Large 1-1/2 inch diameter suits high-load structural and industrial bolted joints

Compatibility

Designed as a standard UNC hex head cap screw for use with 1-1/2 - 6 threaded nuts, tapped holes, or flanged connections requiring a Grade 5 partially threaded fastener per ASME B18.2.1 and SAE J429 specifications.

Installation Notes

Installation is typically performed by qualified millwrights, maintenance mechanics, or mechanical contractors using appropriate hex wrenches or impact tooling sized for the fastener head. Always verify that the mating nut or tapped hole thread class and material grade are compatible with Grade 5 fastener requirements before assembly. Follow applicable industry torque guidelines and engineering specifications for the joint; do not substitute this fastener in applications requiring Grade 8 or higher tensile strength without engineering review.
