Value Collection B10746 Hex Cap Screw 1/2-13x4 Grade 8 25pk

Product Description

The VALUE COLLECTION B10746 is a fully threaded hex head cap screw designed for high-strength mechanical fastening applications. Sized at 1/2-13 UNC thread with a 4-inch length under head, this fastener is manufactured from Grade 8 steel and finished with a zinc yellow dichromate coating that provides corrosion resistance and identification at a glance. It meets ASME B18.2.1 and SAE J429 standards, making it a reliable choice wherever a traceable, specification-grade fastener is required. Sold in a package of 25 pieces, it suits both job-lot purchasing and general stock replenishment for maintenance crews, contractors, and fabrication shops.

This screw is suited for structural and mechanical assemblies that demand Grade 8 tensile strength, including equipment mounting, steel fabrication, heavy machinery repair, and general industrial maintenance. The fully threaded shank provides maximum thread engagement across the entire fastened length, which is advantageous in thin-material or through-bolt applications. The 1/2-13 UNC thread form is one of the most common inch-series coarse threads in North American trade use, making mating hardware readily available.

Key Features

• Grade 8 steel construction meets SAE J429 minimum proof load and tensile strength requirements for high-stress applications
• Zinc yellow dichromate finish provides corrosion resistance and serves as a visual Grade 8 identifier
• Fully threaded shank maximizes thread engagement along the full 4-inch length under head
• 1/2-13 UNC thread form conforms to ASME B18.2.1 dimensional standards
• Package quantity of 25 pieces supports stocking, job kitting, and bulk maintenance use

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, lock nuts, and threaded inserts in inch-series fastener assemblies conforming to ASME and SAE standards.

Installation Notes

Installation is performed using a standard hex wrench, socket, or impact driver sized for a 1/2-13 hex head fastener. Verify that mating hardware thread class and material grade are compatible with the application load requirements before installation. Do not mix with metric hardware. Follow applicable codes and torque guidelines from the equipment manufacturer or relevant structural standards when determining final seating torque.
