Value Collection 101217PR Set Screw 8-36 X 3/16 in Cup Point

Product Description

The VALUE COLLECTION 101217PR is a cup point set screw designed for securing components onto shafts, spindles, and other cylindrical workpieces without protruding above the surface. Sized at 8-36 x 3/16 inches overall length with a 5/64-inch hex drive, this fastener is manufactured from alloy steel to Grade 8 strength. The cup point geometry bites into the mating surface under torque, providing a firm, vibration-resistant grip. It meets ASME/ANSI B18.3 and ASTM F912 standards, making it appropriate for mechanical assemblies where dimensional conformance and material traceability are required.

This set screw is suited for light industrial and precision mechanical applications including collars, gears, pulleys, and shaft couplings. The fine 36-TPI UNF thread pitch allows for controlled, incremental tightening in tight-tolerance assemblies. Machinists, maintenance technicians, and millwrights typically install this fastener in production and field-service settings. It is sold in minimum order quantities of 100 pieces per order, with each package containing 1 piece.

Key Features

• Cup point geometry provides positive bite into shaft or mating surface for vibration-resistant retention
• Grade 8 alloy steel construction for high tensile and torsional strength
• Fine UNF 8-36 thread pitch for precise incremental adjustment in close-tolerance applications
• 5/64-inch hex (Allen) drive for use with standard hex key sets
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Fully headless profile sits flush or below surface to avoid interference with surrounding components

Compatibility

Designed as a standard UNF 8-36 set screw for use in any threaded bore or tapped hole conforming to ASME/ANSI B18.3 specifications. Suitable for collars, couplings, pulleys, gears, and similar shaft-retention applications requiring a cup point fastener.

Installation Notes

Installation is performed with a 5/64-inch hex key; ensure the key is fully seated to avoid rounding the drive socket. De-energize and lock out any rotating equipment before accessing shaft-mounted components. Do not exceed the rated torque range for the thread size and material grade. Inspect the cup point and threaded bore for burrs or contamination before installation to ensure full thread engagement.
