Value Collection 101281P Set Screw 10-32 X 1/2 in Cup Point

Product Description

The VALUE COLLECTION 101281P is a 10-32 x 1/2 inch cup point set screw manufactured from Grade 8 alloy steel. Set screws of this type are fully threaded, headless fasteners used to secure a component — such as a pulley, gear, or collar — onto a shaft by applying clamping force through the cup point tip. Driven with a 3/32 inch hex key, this screw meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards. The cup point geometry bites into the mating shaft surface for positive holding power without requiring a locking nut. This fastener is installed by licensed mechanical tradespeople, maintenance technicians, and machine assembly professionals.

This set screw is suited for use in mechanical assemblies across HVAC equipment, light industrial machinery, motor drives, and general manufacturing applications. The 10-32 thread designation (size 10, 32 threads per inch) is common in precision equipment and smaller-diameter shaft collar applications. The 1/2 inch overall length provides sufficient engagement depth for standard collar and hub thicknesses encountered in trade and light industrial settings.

Key Features

• Cup point tip bites into shaft surface for strong rotational and axial holding force
• Grade 8 alloy steel construction provides high tensile strength for demanding clamping applications
• 3/32 inch hex drive compatible with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards
• 10-32 UNC/UNF thread is compatible with both unified coarse and fine tapped holes of matching pitch
• Fully threaded, headless design allows flush or recessed installation in tapped bores

Compatibility

Designed as a standard 10-32 x 1/2 inch cup point set screw for use in any tapped bore conforming to ASME/ANSI B18.3 specifications at this thread size and length.

Installation Notes

Installation is performed by mechanical technicians or millwrights using a 3/32 inch hex key. Ensure the mating component is fully de-energized and the shaft is stationary before installing or adjusting set screws. Threads should be clean and free of debris before driving to avoid cross-threading. Do not exceed the tapped hole depth, and verify thread engagement is sufficient for the load before returning equipment to service.
