Value Collection 604151PR Set Screw 8-32 X 1/8 in Cone Point

Product Description

The VALUE COLLECTION 604151PR is a Grade 8 alloy steel set screw in the 8-32 UNC thread size with an overall length of 1/8 inch. It features a cone point tip that bites into the mating surface for a firm, vibration-resistant hold. The 5/64-inch hex drive accepts a standard hex key for installation and removal. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and mechanical assemblers use set screws like this to lock collars, pulleys, gears, and similar components onto shafts or into housings without a protruding head.

The 604151PR is suited for light-duty mechanical assemblies where a flush, headless fastener is required. The cone point geometry concentrates clamping force at a single contact area, making it effective on hardened or smooth shaft surfaces. Typical applications include shaft collars, set collar locking, and small-component positioning in industrial machinery, HVAC equipment, and electrical enclosures. This fastener is sold individually but requires a minimum order of 100 pieces.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cone point tip for positive bite and vibration-resistant locking
• 5/64-inch hex (Allen) drive for precise torque application in tight clearances
• 8-32 UNC thread for compatibility with standard inch-series tapped holes
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits flush or below surface for clearance-critical assemblies

Compatibility

Designed as a standard inch-series set screw for use in any 8-32 UNC tapped hole requiring a cone point, headless fastener per ASME/ANSI B18.3.

Installation Notes

Installation requires a 5/64-inch hex key or Allen wrench. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before accessing rotating or moving components that require this fastener. Follow applicable mechanical assembly standards and do not exceed the rated torsional capacity of the screw by over-driving.
