Value Collection 101004PR Set Screw 0-80 Grade 8

Product Description

The VALUE COLLECTION 101004PR is a Grade 8 alloy steel cup point set screw in a 0-80 thread size with an overall length of 3/32 inches. Set screws of this type are fully threaded fasteners with no head - they seat flush or below a surface and are driven with a hex key. The cup point digs into the mating shaft or surface to resist rotation and axial movement. This screw conforms to ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance for precision and structural fastening applications.

This set screw is used in applications requiring a low-profile or recessed fastener where a standard headed screw would interfere with adjacent components. Typical uses include securing collars, gears, pulleys, and knobs to shafts in small mechanical assemblies, instruments, and light industrial equipment. The 0-80 thread designation is the finest standard inch-series thread available, making this screw well suited for miniature or precision assemblies where space and tolerances are tight.

Key Features

• Cup point geometry bites into mating surface for strong rotational and axial hold
• Grade 8 alloy steel construction for high tensile and torsional strength relative to size
• 0-80 UNF thread - finest standard inch-series thread, designed for precision miniature assemblies
• Headless hex drive design allows flush or sub-flush installation
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• 0.0280-inch hex key size for accurate driver selection

Compatibility

Designed as an OEM-style and general-use replacement or stock fastener for any application requiring a 0-80 UNF cup point set screw with a 3/32-inch overall length and hex drive.

Installation Notes

Installation is performed with a 0.0280-inch hex key - using an incorrect key size risks stripping the socket. Ensure the mating shaft or surface is clean and free of debris before seating the cup point. De-energize and lock out any rotating or powered equipment before installing or adjusting set screws per applicable safety procedures. Do not exceed the rated torsional load for a Grade 8 fastener at this thread size, and apply thread-locking compound if vibration is a concern in the application.
