Value Collection 101163PR Set Screw 6-32 X 7/8 in Cup Point Grade 8

Product Description

The VALUE COLLECTION 101163PR is a cup point set screw designed for secure, no-protrusion fastening in mechanical assemblies. Threaded 6-32 UNC with an overall length of 7/8 inches, this screw is driven by a 1/16-inch hex key and seats with a cup point that bites into the mating surface to resist rotation and axial movement. Manufactured from Grade 8 alloy steel, it meets ASME/ANSI B18.3 and ASTM F912 standards, making it appropriate for applications that require a certified, dimensionally consistent fastener. It is commonly installed by machinists, maintenance technicians, and trade professionals working with shafts, collars, and assemblies where a flush or recessed fastener is required.

This set screw is suited for use in light mechanical assemblies, motor shaft collars, pulleys, gears, and similar components found in HVAC equipment, electrical enclosures, and general industrial machinery. The cup point geometry provides a positive bite on soft or hardened shafts without requiring a through-hole or protruding head. The 6-32 UNC thread size is a standard coarse thread widely used in small mechanical and electromechanical assemblies across residential and commercial applications.

Key Features

• Cup point tip bites into mating shaft surface to resist rotation and axial movement
• Grade 8 alloy steel construction for high tensile and torsional strength
• 1/16-inch hex drive for use with standard Allen keys in tight clearance locations
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• 6-32 UNC thread standard ensures broad compatibility with tapped holes in small assemblies
• Headless design sits flush or below the surface for zero-protrusion installations

Compatibility

Designed as a standard 6-32 UNC cup point set screw for use in any tapped hole conforming to ASME/ANSI B18.3 specifications. Suitable for shaft collars, pulleys, gears, and similar mechanical components requiring a headless fastener.

Installation Notes

Installation requires a 1/16-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. Verify the receiving tapped hole is clean, properly threaded to 6-32 UNC, and free of debris before driving the screw. Disconnect power to any rotating or motorized equipment before servicing fasteners on shafts or collars. Follow applicable ASME or equipment manufacturer guidelines for fastener installation procedures.
