Value Collection R52001090 Hex Head Cap Screw Grade 5

Product Description

The VALUE COLLECTION R52001090 is a partially threaded hex head cap screw designed for heavy-duty fastening applications in mechanical, structural, and industrial assemblies. Sized at 1-1/2-6 UNC with a 6-1/2-inch length under head, this fastener is manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. Compliant with ASME B18.2.1 and SAE J429 standards, it provides reliable clamping force in high-load connections. Licensed tradespeople, millwrights, pipefitters, and mechanical contractors commonly specify this size for heavy equipment and structural bolting work.

This cap screw is suited for large-scale mechanical assemblies, industrial equipment mounting, structural steel connections, and heavy machinery fabrication. The 1-1/2-6 UNC thread series and Grade 5 specification make it appropriate for applications requiring controlled tensile strength and dimensional consistency per ASME and SAE standards. It is sold individually and is intended for professional installation contexts where torque-critical fastening is required.

Key Features

• 1-1/2-6 UNC thread size for heavy-duty clamping applications
• 6-1/2-inch length under head for deep engagement in thick assemblies
• Grade 5 steel construction meets SAE J429 minimum tensile requirements
• Zinc-plated finish provides baseline corrosion protection
• Partially threaded shank allows shear-load bearing in unthreaded grip zone
• Compliant with ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard UNC hex head cap screw for use in any application requiring a 1-1/2-6 UNC Grade 5 partially threaded fastener per ASME B18.2.1 and SAE J429 specifications.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or structural tradesperson familiar with large-diameter fastener torque requirements. Always verify thread engagement depth and ensure the mating tapped hole or nut meets the same thread standard before assembly. Do not exceed the rated tensile strength of the Grade 5 designation. Follow applicable industry codes and engineering specifications for proper torque values based on joint material and lubrication condition.
