Value Collection 601151PR Set Screw 8-32 X 2 in Cup Point

Product Description

The VALUE COLLECTION 601151PR is a cup point set screw designed for mechanical assemblies where a fastener must apply holding force without a protruding head. It features an 8-32 UNC thread, a 2-inch overall length, and is manufactured from Grade 8 alloy steel for high tensile strength. The 5/64-inch hex drive accepts a standard hex key and allows installation in tight or recessed locations. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards. It is commonly installed by millwrights, maintenance mechanics, and HVAC technicians securing pulleys, collars, and hubs on rotating shafts and mechanical components.

The 601151PR is suited for residential and light commercial mechanical applications where a headless, flush-mount fastener is required. The cup point configuration bites into the mating surface to resist rotational and axial movement without requiring adhesive. Typical applications include securing shaft collars, set-collar assemblies, gear hubs, and similar components in HVAC equipment, pump assemblies, and general mechanical systems.

Key Features

• Grade 8 alloy steel construction provides high tensile and torsional strength
• Cup point geometry bites into mating surfaces to resist shaft rotation and axial movement
• 8-32 UNC thread standard ensures broad compatibility with standard tapped holes
• 5/64-inch hex drive allows installation with a standard hex key in confined spaces
• Headless design sits flush or below the mating surface to eliminate protrusion hazards
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards

Compatibility

Designed as a standard 8-32 UNC cup point set screw for use in any tapped hole or threaded collar requiring an ASME/ANSI B18.3 compliant headless fastener.

Installation Notes

Installation requires a 5/64-inch hex key; confirm the mating component is properly tapped to 8-32 UNC before driving the fastener. De-energize and lock out any rotating equipment before servicing shaft-mounted components secured by set screws. Do not exceed the torque capacity of the alloy steel fastener by using impact tools or extensions not suited to hex-drive set screws. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener seating depth and preload.
