Value Collection 601297PR Set Screw 3/8-24x3 in Cup Point

Product Description

The VALUE COLLECTION 601297PR is a cup point set screw designed for mechanical fastening applications where a headless, flush-mount fastener is required. This screw features a 3/8-24 UNF thread with an overall length of 3 inches and is driven by a 3/16-inch hex key. The cup point geometry bites into the mating shaft or surface to resist rotation and axial movement. Made from alloy steel, the 601297PR meets ASME/ANSI B18.3 and ASTM F912 standards. It is installed by licensed mechanics, machinists, and maintenance technicians working on rotating equipment, shafts, and mechanical assemblies.

This set screw is suited for industrial and mechanical maintenance environments where a UNF threaded, headless fastener is needed to secure collars, gears, pulleys, or hubs to shafts. The cup point is appropriate for use on both hardened and unhardened shaft materials. It fits standard 3/8-24 threaded bores and is commonly used in HVAC equipment assemblies, motor shaft collars, and general mechanical components requiring a permanent or semi-permanent hold without protruding hardware.

Key Features

• Cup point tip bites into shaft surface for positive grip against rotation and axial movement
• 3/8-24 UNF thread form for fine-thread engagement and vibration resistance
• 3 inches overall length provides deep thread engagement in thick hubs or collars
• 3/16-inch hex drive accepts standard hex keys and T-handle drivers
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F912 standards
• Headless design sits flush with or below the mating surface

Compatibility

Designed as an OEM-style replacement or standard stocking fastener for mechanical assemblies requiring a 3/8-24 UNF cup point set screw with a 3-inch overall length.

Installation Notes

Installation requires a 3/16-inch hex key or Allen driver. De-energize and lock out any equipment before servicing rotating components that contain this fastener. Apply the appropriate torque using a calibrated hex torque key per the equipment manufacturer specifications. Thread engagement should be confirmed before returning equipment to service.
