Value Collection 101016PR Set Screw 0-80 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION 101016PR is a 0-80 x 1/4 inch cup point set screw manufactured from Grade 8 alloy steel. Set screws are fully threaded fasteners with no head — they seat flush or below the surface of a workpiece and apply clamping force through a recessed drive. The cup point tip bites into the mating surface to resist rotation and axial movement. This screw is driven with a 0.0280 inch hex key and meets ASME/ANSI B18.3 and ASTM F912 standards. It is suited for precision mechanical assemblies where a low-profile, secure hold is required. Machinists, maintenance technicians, and industrial assemblers are the typical installers.

The 101016PR is used in light-duty mechanical applications where a threaded fastener must lock a shaft, collar, gear, pulley, or similar component in position without protruding above the surrounding surface. The 0-80 thread size is a fine unified thread (UNF), common in miniature mechanical and instrument assemblies. The cup point is a general-purpose point type that provides reliable grip on both hardened and unhardened mating surfaces in residential, commercial, and light industrial equipment.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength relative to fastener size
• Cup point tip bites into mating surface to resist loosening under vibration or load
• 0.0280 inch hex key drive for precise torque application in tight spaces
• UNF 0-80 thread form for use in miniature and instrument-grade assemblies
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards
• Overall length of 1/4 inch suits shallow blind-hole applications

Compatibility

Designed as an OEM-style replacement or stock fastener for miniature mechanical assemblies requiring a headless 0-80 UNF cup point set screw in alloy steel.

Installation Notes

Installation is performed by machinists or mechanical technicians using the correct 0.0280 inch hex key to avoid rounding the drive socket. De-energize or lock out any equipment before servicing fasteners on rotating assemblies. Do not exceed the torque capacity of the 0-80 thread form, as the minor diameter is very small and susceptible to shear. Thread engagement depth in the mating component should be confirmed before installation to ensure secure seating of the cup point.
