Value Collection 601197PR Set Screw 12-24 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION 601197PR is a cup point set screw designed for mechanical fastening applications where a headless, flush-mount fastener is required. This screw features a 12-24 UNC thread with an overall length of 1/4 inch and is driven by a 7/64 inch hex key. Manufactured from alloy steel to ASTM F912 and ASME/ANSI B18.3 standards, it delivers the hardness and shear resistance needed for securing shaft collars, pulleys, gears, and similar rotating or sliding components. Licensed trades and maintenance technicians working on mechanical assemblies, HVAC equipment, or industrial machinery will encounter this fastener type regularly.

Cup point set screws like the 601197PR are used across light and medium-duty mechanical assemblies where the cup point is intended to bite into a shaft or mating surface and resist rotational slippage. Common applications include motor shaft collars, fan blade hubs, valve stems, and small-bore mechanical linkages in both residential and commercial equipment. The 12-24 thread size is a standard coarse-thread designation suited to general-purpose steel and aluminum hardware.

Key Features

• Cup point geometry bites into mating shaft surface to resist torque and axial movement
• 12-24 UNC thread provides reliable engagement in standard tapped holes
• 7/64 inch hex drive accepts standard hex keys and Allen wrenches
• Alloy steel construction meets ASTM F912 hardness and strength requirements
• Conforms to ASME/ANSI B18.3 dimensional standards for set screws
• Compact 1/4 inch overall length suits tight clearance applications

Compatibility

Designed as a standard ASME/ANSI B18.3 set screw for any application requiring a 12-24 UNC cup point fastener with a 7/64 inch hex drive.

Installation Notes

Set screws are typically installed by mechanics, millwrights, or HVAC technicians using a properly sized hex key to avoid rounding the drive socket. Ensure the mating shaft or surface is clean and free of burrs before tightening. Always de-energize or lock out equipment before servicing any mechanical assembly that includes set screws. Do not exceed the torque capacity of the hex drive by using excessive leverage on the key.
