Value Collection 101207PR Set Screw 8-32 5/8in Cup Point

Product Description

The VALUE COLLECTION 101207PR is a cup point set screw designed for mechanical assemblies where a headless fastener is required to secure a component against a shaft or within a housing. Sized at 8-32 UNC threading with an overall length of 5/8 inches, this fastener is driven with a 5/64 inch hex key. Manufactured from Grade 8 alloy steel, it delivers the hardness and tensile strength needed for high-load holding applications. It meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians commonly install these in production and service environments.

Cup point set screws like the 101207PR are used across a wide range of mechanical and industrial applications, including shaft collars, pulleys, sprockets, gears, and positioning fixtures. The cup point geometry bites into the mating surface to resist axial and rotational movement without a separate locking element. This makes them a standard choice in both light and moderate-duty drive systems where repeated adjustments may be required. Sold in minimum order quantities of 100, this fastener is suited for shop stock, assembly line supply, and field service kits.

Key Features

• Cup point geometry grips mating shaft surfaces to resist axial and rotational movement
• Grade 8 alloy steel construction provides high hardness and tensile strength
• 8-32 UNC thread form for compatibility with standard tapped holes in that thread class
• 5/64 inch hex drive accepts standard hex keys and L-wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits flush or below the surface of the mating part

Compatibility

Designed as a standard 8-32 UNC cup point set screw for use in any tapped hole conforming to that thread size and pitch, including shaft collars, pulleys, and similar mechanical assemblies requiring a headless clamping fastener.

Installation Notes

Installation requires a 5/64 inch hex key or L-wrench; ensure the mating tapped hole is clean and free of debris before threading. Power down and de-energize any rotating equipment before servicing fasteners on shafts or drive components. Do not exceed the torque capacity appropriate for the thread size and material grade. Inspect the cup point and mating surface for wear when reassembling components that have been adjusted repeatedly.
