Value Collection 601244PR Set Screw 5/16-18 X 2-1/4 in Cup Point

Product Description

The VALUE COLLECTION 601244PR is a cup point set screw designed for clamping, positioning, and locking components onto shafts and in bores. Manufactured from alloy steel, this fastener offers the strength and hardness needed for demanding mechanical assemblies. The cup point tip bites into the mating surface to resist rotation and axial movement under load. It is driven with a 5/32-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it a code-compliant choice for precision mechanical work. Machinists, maintenance technicians, and industrial assemblers regularly specify this style of fastener for shaft collars, pulleys, and set-screw couplings.

This set screw is suited for use in light industrial machinery, HVAC equipment assemblies, pump and motor shaft applications, and general mechanical maintenance. The 5/16-18 UNC thread and 2-1/4-inch overall length make it appropriate for medium-depth engagement in steel or cast-iron components. It is sold individually per package with a minimum order quantity of 10 pieces, making it practical for service kits and shop stock replenishment.

Key Features

• Cup point tip for secure, positive contact on shaft surfaces
• Alloy steel construction for high tensile and torsional strength
• 5/16-18 UNC thread for broad fixture and tooling compatibility
• 2-1/4-inch overall length for medium-to-deep engagement applications
• 5/32-inch hex drive for standard Allen key installation
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as a standard 5/16-18 UNC cup point set screw for use in any fixture, collar, hub, or mechanical assembly that accepts this thread size and overall length.

Installation Notes

Installation is typically performed by a machinist or maintenance technician using a 5/32-inch hex key or Allen driver. Always de-energize and lock out any machinery before servicing fasteners on rotating components. Ensure mating threads are clean and free of debris before driving the screw to avoid cross-threading. Do not exceed the rated torque for the thread size as specified by ASME standards for alloy steel fasteners.
