Value Collection D39137 Hex Head Cap Screw 9/16-12 X 3 in

Product Description

The VALUE COLLECTION D39137 is a 9/16-12 UNC hex head cap screw designed for heavy-duty fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, it delivers high tensile strength and corrosion resistance in demanding service environments. The fastener measures 3 inches under the head with partial threading along the shank, conforming to ASME B18.2.1 dimensional standards. It is intended for installation by machinists, millwrights, maintenance technicians, and other trade professionals requiring a reliable, code-compliant fastener in inch-series configurations.

This cap screw is suited for use in high-load bolted connections where Grade 8 strength is required, such as equipment mounting, structural steel assemblies, and heavy machinery fabrication. The partial thread length provides full shank bearing across joint interfaces, making it appropriate for applications where shear load distribution across the grip length is critical. The zinc yellow dichromate coating provides mild corrosion protection suitable for indoor and sheltered outdoor installations.

Compatibility

Designed as an OEM-style replacement or maintenance fastener for any application requiring a 9/16-12 UNC hex head cap screw in Grade 8 steel with a 3-inch under-head length.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with proper torque procedures for Grade 8 fasteners. Always consult the equipment manufacturer torque specifications and applicable standards before final tightening. Ensure mating threads are clean and free of debris before assembly. Do not substitute a lower-grade fastener in applications specifying Grade 8.
