Value Collection 601263PR Set Screw 5/16-24 X 2-1/4 in Cup Point

Product Description

The VALUE COLLECTION 601263PR is a cup point set screw designed for secure, no-protrusion fastening in mechanical assemblies. Sized at 5/16-24 UNF thread with an overall length of 2.25 inches, it is driven with a 5/32-inch hex key. The cup point digs into the mating surface to resist rotational and axial movement, making it a reliable choice for shaft-to-hub connections, collars, and similar applications. Manufactured from alloy steel, this set screw meets ASME/ANSI B18.3 and ASTM F912 standards. It is a practical, conforming fastener stocked for maintenance, repair, and production use across industrial and mechanical trades.

This set screw is suited for use in mechanical power transmission components such as shaft collars, pulleys, gears, and couplings where a flush or recessed fastener is required. The cup point style is commonly selected when a semi-permanent bite into a soft shaft is acceptable. It is appropriate for both light-duty and moderate-load applications in industrial, HVAC equipment, and general mechanical assembly environments. Minimum order quantity is 10 pieces; individual package quantity is 1.

Key Features

• Cup point geometry bites into mating surface for strong resistance to shaft slippage
• 5/16-24 UNF thread provides fine-pitch engagement for precise clamping force adjustment
• 2.25-inch overall length accommodates deeper engagement in thicker hubs or collars
• Driven with a 5/32-inch hex key for recessed, low-profile installation
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F912 standards
• No exposed head — fully recessed once installed, eliminating snag hazards

Compatibility

Designed as a standard 5/16-24 UNF cup point set screw conforming to ASME/ANSI B18.3 and ASTM F912, suitable for use in any application requiring that thread size and overall length.

Installation Notes

Set screws of this type are typically installed by machinists, millwrights, or maintenance technicians using a 5/32-inch hex key or Allen driver. De-energize and lock out any rotating equipment before installing or adjusting set screws on shafts. Do not exceed the torque appropriate for the thread size and material of the receiving component. Inspect the mating shaft surface after removal, as the cup point will leave an indentation.
