Value Collection 101197P Set Screw 8-32 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION 101197P is a cup point set screw designed for secure, positive clamping against a shaft or mating surface. Sized at 8-32 x 1/4 inches overall length, it uses a 5/64-inch hex drive and is manufactured from Grade 8 alloy steel for high tensile strength and resistance to loosening under load. The cup point geometry bites into the mating surface to resist rotational and axial movement. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards. It is used by maintenance technicians, machinists, and trade professionals in mechanical assemblies, set screw collars, pulleys, and shaft-mounted components.

The 101197P is suited for light-duty to medium-duty mechanical assemblies where a compact, headless fastener is required. Common applications include securing set screw shaft collars, sprockets, pulleys, gears, and similar components in HVAC equipment, plumbing assemblies, and general industrial machinery. The 8-32 UNC/UNF thread is one of the most common machine screw sizes, making this screw a standard replacement or stock fastener across a wide range of equipment and field repair scenarios. Supplied as individual pieces with a minimum order quantity of 100.

Key Features

• Cup point geometry bites into shaft surface to resist rotational and axial movement
• Grade 8 alloy steel construction for high tensile and torsional strength
• 5/64-inch hex drive accepts standard hex keys and hex bit drivers
• Meets ASME/ANSI B18.3 and ASTM F912 standards for dimensional and mechanical compliance
• 8-32 UNC/UNF thread for broad compatibility with standard tapped holes
• Headless design sits flush or below surface for clearance-sensitive installations

Compatibility

Designed as a standard 8-32 cup point set screw for use in any tapped hole conforming to UNC/UNF thread standards. Suitable for set screw collars, pulleys, sprockets, and other shaft-mounted hardware requiring an 8-32 headless fastener.

Installation Notes

Installation requires a 5/64-inch hex key or matching hex bit driver. Power down and de-energize any equipment before servicing shaft-mounted components secured with set screws. Do not overtighten — excessive torque can strip the hex socket or damage the mating shaft. Confirm thread engagement is clean and free of debris before driving the screw to final position.
