Value Collection 101022PR Set Screw 1-72 X 3/32 in Cup Point

Product Description

The VALUE COLLECTION 101022PR is a Grade 8 alloy steel set screw used to secure components onto shafts and in threaded assemblies where a flush or recessed fastener is required. It features a cup point, which bites into the mating surface for positive holding power, and is driven with a hex key. At a thread size of 1-72 UNF and an overall length of 3/32 inches, this fastener is intended for precision applications where tight tolerances and minimal fastener footprint matter. It conforms to ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance for professional and industrial use.

This set screw is suited for small mechanical assemblies, instrument components, and precision equipment where a 1-72 UNF thread is specified. Typical applications include securing collars, pulleys, knobs, and small gears onto shafts in both OEM manufacturing and field repair situations. The Grade 8 alloy steel construction provides the hardness and shear strength needed in high-stress clamping applications. Machinists, maintenance technicians, and assembly professionals working with fine-thread fastener specifications will find this screw appropriate for demanding light-assembly work.

Key Features

• Cup point geometry bites into mating surfaces for reliable rotational and axial holding
• 1-72 UNF thread provides fine-thread engagement for precise clamping adjustment
• Grade 8 alloy steel construction delivers high hardness and tensile strength
• Hex drive with 0.028 inch key size suits standard hex key sets for tight-access installation
• Conforms to ASME/ANSI B18.3 and ASTM F912 for dimensional and material compliance
• Headless design sits flush or below surface, eliminating protrusion hazards in rotating assemblies

Compatibility

Designed as a standard 1-72 UNF set screw replacement or OEM-specification fastener for precision mechanical assemblies requiring an ASME/ANSI B18.3-compliant cup point headless screw.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 0.028 inch hex key. Ensure the threaded bore is clean and free of debris before driving the screw. Do not exceed the rated drive torque for this thread size, as over-torquing a Grade 8 set screw in a fine thread can strip the bore or shear the screw. Degrease mating surfaces if maximum cup point bite is required for the application.
