Value Collection 101315PR Set Screw 1/4-20 X 7/16 in Cup Point

Product Description

The VALUE COLLECTION 101315PR is a cup point set screw designed for secure, non-permanent fastening in mechanical assemblies. Sized at 1/4-20 thread with a 7/16-inch overall length, this fully threaded fastener seats into a mating threaded bore and uses its cup-shaped point to bite into a shaft or mating surface, resisting rotation and axial movement. Driven by a 1/8-inch hex key, it meets ASME/ANSI B18.3 and ASTM F912 standards. Made from alloy steel, it delivers the hardness and shear strength required for general industrial and mechanical maintenance applications.

Cup point set screws like the 101315PR are commonly used in shaft collars, pulleys, gears, couplings, and similar rotating or sliding components where a positive grip on a shaft is needed. The cup point geometry creates a small indentation in the mating surface, providing positive locking without requiring adhesives or additional hardware. This fastener is appropriate for light to medium-duty industrial assemblies, HVAC equipment drives, pump shafts, and general manufacturing or repair work.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard threaded bores
• 7/16-inch overall length suits shallow boss and collar applications
• Cup point geometry bites into shaft surface for positive rotational and axial hold
• 1/8-inch hex drive accepts standard Allen or hex key wrenches
• Alloy steel construction provides high hardness and shear strength
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards

Compatibility

Designed as a standard 1/4-20 UNC cup point set screw suitable for use in any threaded bore conforming to ASME/ANSI B18.3 specifications, including shaft collars, couplings, pulleys, and gears requiring a 7/16-inch length fastener.

Installation Notes

Installation is performed with a 1/8-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize and lock out any rotating equipment before servicing shaft-mounted components secured by set screws. Inspect the mating shaft surface for debris or damage before installation. Follow applicable machinery safety standards and facility lockout/tagout procedures.
