Value Collection MP72164 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION MP72164 is a hex socket cap screw designed for secure, high-strength fastening in mechanical assemblies and structural applications. It features a 3/8-16 UNC thread size and a 5/16-inch hex drive, requiring an Allen wrench or hex key for installation. The screw measures 1-3/4 inches in length under the head and is partially threaded. Constructed from alloy steel with a black oxide finish, this fastener resists corrosion and handles demanding load conditions. It conforms to ASME B18.3 and ASTM A574 standards. Sold in a package of 10.

This cap screw is suited for use in industrial machinery, HVAC equipment mounting, structural brackets, and general mechanical assembly where a recessed-drive, high-strength fastener is required. The black oxide coating provides mild corrosion resistance, making it appropriate for indoor and protected outdoor installations. Trades including HVAC technicians, pipefitters, millwrights, and general contractors commonly use this fastener type when assembling or securing equipment to frames, panels, and support structures.

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw for use in any application requiring an ASME B18.3 or ASTM A574 compliant alloy steel fastener with a 5/16-inch hex drive.

Installation Notes

Install using a calibrated torque wrench with a 5/16-inch hex bit to avoid stripping the socket or over-stressing the threads. Ensure the mating tapped hole is clean and free of debris before installation. Always de-energize and lock out equipment before replacing fasteners on live assemblies. Follow applicable mechanical codes and equipment manufacturer guidelines for proper torque procedures.
