Value Collection 451074PR Hex Head Cap Screw 3/8-16 X 7 in Grade 8

Product Description

The VALUE COLLECTION 451074PR is a Grade 8 steel hex head cap screw in a 3/8-16 UNC thread size with a 7-inch length under head. Partially threaded and finished bright/uncoated, this fastener is built for high-strength bolted assemblies where clamping force and tensile strength matter. Grade 8 steel delivers significantly higher proof load and tensile strength compared to Grades 2 or 5, making it a common choice for structural connections, heavy equipment, and load-bearing mechanical assemblies. It conforms to ASME B18.2.1, the standard governing dimensions and tolerances for inch-series hex cap screws.

This cap screw is suited for use in industrial, agricultural, heavy equipment, and general mechanical applications where high-strength fastening is required. The partial thread configuration provides a smooth shank section under the head, which is preferred in applications requiring shear resistance or precise hole alignment. Installers working on structural steel, machinery frames, agricultural implements, or similar assemblies will find this screw appropriate for standard through-bolt and nut configurations. The 9/16-inch hex key size is compatible with standard SAE wrenching tools.

Key Features

• Grade 8 steel construction provides high tensile strength for demanding structural applications
• Partially threaded shank supports shear-load resistance and accurate hole registration
• 3/8-16 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• Bright/uncoated finish — suitable for dry or protected environments; no coating to affect thread fit
• Conforms to ASME B18.2.1 dimensional standards for hex cap screws
• 9/16-inch hex drive for use with standard open-end, box, or socket wrenches

Compatibility

Designed for use with standard 3/8-16 UNC inch-series hex nuts, flat washers, and lock washers in structural or mechanical bolted joint assemblies.

Installation Notes

Installation is typically performed by maintenance technicians, millwrights, or general tradespeople using standard hand or power wrenching tools in the 9/16-inch SAE size. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Torque to the value specified in the applicable joint design or equipment service documentation — do not apply a generic torque value without confirming the joint requirements. In structural applications, consult applicable codes and engineering specifications before finalizing fastener selection and installation.
