Value Collection 601003PR Set Screw 0-80 X 5/32 in Cup Point

Product Description

The VALUE COLLECTION 601003PR is a Grade 8 alloy steel cup point set screw in a 0-80 thread size with a 5/32-inch overall length. Set screws are fully threaded, headless fasteners used to secure one component against another — typically a collar, gear, pulley, or hub onto a shaft. The cup point digs into the mating surface to resist rotational and axial movement. Drive is internal hex (Allen key), requiring a 0.028-inch hex key. This screw conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it a recognized choice for precision mechanical assemblies where compact fastening is required.

This set screw is suited for light-duty mechanical and instrumentation applications where a small-diameter, fine-thread fastener is needed. The 0-80 UNF thread is among the smallest unified fine thread designations, commonly found in optical equipment, miniature motors, instrument housings, and precision fabrication work. It is installed by machinists, millwrights, and maintenance technicians working on small mechanical assemblies. The cup point provides reliable holding force in applications where slight surface indentation is acceptable on the mating shaft or component.

Key Features

• Grade 8 alloy steel construction for high tensile strength in a miniature fastener
• Cup point geometry bites into mating surface to resist slippage under load
• 0-80 UNF thread standard — among the finest unified thread designations available
• Internal hex drive requires a 0.028-inch hex key for installation and removal
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits flush or below surface, eliminating protrusion hazards

Compatibility

Designed as an OEM-style replacement or new-installation fastener for applications requiring a 0-80 UNF thread, 5/32-inch overall length, cup point set screw in alloy steel.

Installation Notes

Set screws of this size are typically installed by machinists or precision maintenance technicians using a calibrated hex key of the correct size — a 0.028-inch hex key is required here. Do not overtighten; miniature set screws are susceptible to thread stripping and key engagement damage when excessive torque is applied. Ensure the receiving threaded hole is clean and free of debris before installation. Always de-energize or lock out any equipment before accessing rotating components secured by set screws.
