Value Collection 40530 Set Screw 5/16-18 X 5/16 in Grade 8

Product Description

The VALUE COLLECTION 40530 is a 5/16-18 knurled cup point set screw made from Grade 8 alloy steel, designed for secure, vibration-resistant fastening in mechanical assemblies. The knurled cup point bites into the mating surface to resist rotation and axial movement without requiring a through-hole. Driven by a 5/32-inch hex key, this headless fastener sits flush or below the surface of the workpiece. It conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it a code-compliant choice for demanding industrial and mechanical applications. This package contains 50 pieces.

This set screw is suited for use in shaft collars, shaft-to-hub connections, adjustment mechanisms, and clamping applications across HVAC equipment, pumps, motors, and general mechanical assemblies. The Grade 8 alloy steel construction provides high tensile strength for moderate to heavy clamping loads. Licensed trades and maintenance technicians working on rotating equipment or drive assemblies will find this a standard stock item for fieldwork and shop use alike.

Compatibility

Designed as a standard UNC 5/16-18 threaded set screw for use in any tapped hole with a matching 5/16-18 UNC thread, commonly found in shaft collars, mechanical couplings, and adjustable mechanical components.

Installation Notes

Installation requires a 5/32-inch hex key or Allen wrench. Power down and de-energize any rotating equipment before installing or removing set screws. Ensure the tapped hole threads are clean and free of debris before driving the fastener. Do not exceed the rated torque for the fastener size and grade as specified by applicable mechanical standards.
