Value Collection 601312PR Set Screw 7/16-20 X 7/8 in Cup Point

Product Description

The VALUE COLLECTION 601312PR is a cup point set screw designed for secure, load-bearing fastening in mechanical assemblies. Manufactured from alloy steel, it provides the hardness and shear strength needed to hold shafts, collars, and hubs firmly in place under torque and vibration. The 7/16-20 UNF thread delivers fine-pitch engagement for precise axial adjustment, while the cup point bites into the mating surface to resist rotation. Drive is a 7/32-inch hex (Allen) socket. This screw meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards, making it a verifiable specification fit for engineered assemblies.

The 601312PR is used in industrial and mechanical maintenance applications where a headless fastener is required to lock a component onto a shaft without protruding above the surface. Typical installations include motor shafts, set-collar assemblies, gear hubs, pulleys, and similar rotating or sliding components. Trades and maintenance professionals working on HVAC equipment, pumps, fans, and general mechanical systems will find this screw appropriate for standard shaft-locking tasks. Minimum order quantity is 100 pieces per order, sold as individual unit packages.

Key Features

• Cup point geometry bites into shaft surface to resist axial and rotational movement
• 7/16-20 UNF fine-pitch thread for precise depth adjustment and strong thread engagement
• Alloy steel construction provides high hardness and shear strength
• 7/32-inch hex drive accepts standard Allen wrenches and hex keys
• Meets ASME/ANSI B18.3 and ASTM F912 standards for dimensional and mechanical conformance
• Headless design allows flush or sub-flush installation in bored holes

Compatibility

Designed as a standard ASME/ANSI B18.3 cup point set screw suitable for any mechanical assembly requiring a 7/16-20 UNF headless fastener with a 7/32-inch hex drive.

Installation Notes

Installation is typically performed by maintenance technicians or millwrights using a 7/32-inch hex key or Allen wrench. Ensure the shaft and bore are clean and free of debris before threading the screw into the tapped hole. Do not over-drive the screw, as the cup point can embed too deeply into soft shaft materials and make removal difficult. Follow applicable machinery safety lockout/tagout (LOTO) procedures before working on rotating components.
