Value Collection 101531PR Set Screw 7/16-14 X 1-1/4 in Cup Point

Product Description

The VALUE COLLECTION 101531PR is a cup point set screw designed for secure shaft-to-hub and collar fastening applications in mechanical assemblies. Sized at 7/16-14 thread with an overall length of 1-1/4 inches, this screw is manufactured from Grade 8 alloy steel for high tensile strength and resistance to loosening under load. Drive engagement is via a 7/32-inch hex key socket. It conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it a code-compliant choice for production and maintenance work across industrial, HVAC, and mechanical trade applications.

Cup point set screws are used wherever a fastener must bite into a shaft or mating surface to prevent rotational or axial movement without a protruding head. Common applications include set collars, shaft couplings, pulleys, and gear hubs. This screw is appropriate for general mechanical assembly and field-service work in residential and light commercial equipment, as well as industrial machinery requiring UNC-threaded fasteners at this size.

Key Features

• Cup point tip for positive shaft engagement and resistance to rotation under load
• Grade 8 alloy steel construction for high tensile and proof-load strength
• 7/16-14 UNC thread form for broad compatibility with standard tapped holes
• 7/32-inch hex drive for use with standard Allen or hex key sets
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• Headless design allows full recessing below the mating surface

Compatibility

Designed as an OEM-style and general-purpose replacement set screw for mechanical assemblies requiring a 7/16-14 UNC thread, 1-1/4-inch overall length cup point headless set screw per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 7/32-inch hex key or Allen wrench; ensure the key is fully seated before applying torque to prevent drive rounding. Always power down and de-energize or lock out equipment before accessing rotating components such as shafts, couplings, or pulleys. Clean and inspect the tapped hole for debris or damage before threading the screw in. Follow applicable machine safety and mechanical codes for the equipment being serviced.
