Value Collection 101007PR Set Screw 0-80 X 1/8 in Cup Point

Product Description

The VALUE COLLECTION 101007PR is a 0-80 UNF cup point set screw manufactured from Grade 8 alloy steel. Set screws are headless fasteners used to secure a component — such as a pulley, collar, or gear — against a shaft by applying direct clamping force through the point. The cup point style creates a small indent on the shaft surface for positive retention without the screw backing out under vibration. At 1/8 inch overall length with a 0.0280-inch hex key drive, this screw is suited for precision assemblies and tight clearance applications. It meets ASME/ANSI B18.3 and ASTM F912 standards.

This set screw is appropriate for mechanical and electromechanical assemblies where a small-diameter, fine-thread fastener is required. Typical applications include instrument mechanisms, small motor shaft retention, encoder collars, and light-duty linkage assemblies. The 0-80 thread is the finest standard thread in the inch series and is commonly found in precision instruments, electronics enclosures, and miniature mechanical components. Installation is typically performed by machinists, assembly technicians, or field service personnel working on precision equipment.

Key Features

• Cup point geometry creates a positive seating impression on the mating shaft for vibration-resistant retention
• Grade 8 alloy steel construction provides high tensile and torsional strength relative to fastener size
• 0-80 UNF thread form offers fine pitch engagement in thin or close-tolerance tapped bores
• Hex socket drive (0.0280-inch key size) allows installation in recessed or flush configurations
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Sold individually; minimum order quantity of 100 units per order

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cup point set screw for any application requiring a 0-80 UNF thread, 1/8 inch overall length, and a 0.0280-inch hex key drive.

Installation Notes

Use the correct 0.0280-inch hex key to avoid rounding the socket. Ensure the tapped bore is clean and free of debris before threading the screw to prevent cross-threading in this fine-pitch thread form. Apply appropriate torque for the fastener size and application — consult the relevant mechanical assembly specification or standards table. Avoid over-tightening, which can strip the 0-80 thread or shear the screw body at this small diameter.
