Value Collection MS16997-80 Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION MS16997-80 is a hex socket cap screw designed for secure fastening in mechanical assemblies, structural connections, and industrial maintenance applications. It features a 5/16-18 UNC thread size and a 1-inch length under the head, with full threading along the entire shank. The drive is a 1/4-inch hex socket, suited for use with standard hex keys or socket drive tools. The fastener is machined from 4037 alloy steel and finished with a yellow cadmium plating for corrosion resistance. It conforms to ASME B18.3 dimensional standards, making it a direct match for spec-controlled work orders and MRO applications.

This screw is used across a wide range of trade and industrial settings where a recessed-drive cap screw is required. Typical applications include machinery assembly, HVAC equipment frames, electrical panel mounting, pump and motor mounting, and general mechanical maintenance. The fully threaded shank allows full thread engagement across the entire grip length, which is useful in thin-material or close-tolerance installations. The yellow cadmium finish adds a layer of protection in environments with moderate moisture exposure.

Compatibility

Designed as an OEM-style replacement or MRO fastener for applications requiring a 5/16-18 UNC hex socket cap screw per ASME B18.3.

Installation Notes

Installation is typically performed by maintenance mechanics, millwrights, or trade technicians using a 1/4-inch hex key or socket driver. Always ensure mating threads are clean and free of debris before installation. Do not exceed the torque rating specified by the equipment manufacturer for 5/16-18 fasteners in the applicable material. Cadmium-plated fasteners should be handled in accordance with applicable workplace safety guidelines due to the hazardous nature of cadmium compounds.
