Value Collection 101131PR Set Screw 5-44 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION 101131PR is a cup point set screw designed for secure, flush fastening in mechanical assemblies where a protruding head is not acceptable. Manufactured from Grade 8 alloy steel, this screw delivers high tensile and torsional strength suited to demanding industrial and trade applications. It features a 5-44 UNF thread form, an overall length of 1/4 inch, and a 1/16 inch hex drive socket. The cup point bites into the mating surface to resist rotation and axial movement without permanent deformation to softer shaft materials. Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards.

This set screw is used in light mechanical assemblies where a small-diameter, fine-thread fastener is required to secure a shaft, collar, gear, or hub in position. The 5-44 UNF thread is common in precision instruments, small motors, and tight-clearance assemblies in HVAC, electrical, and industrial equipment. Installation requires a 1/16 inch hex key. Minimum order quantity is 100 pieces per order; package quantity is 1.

Key Features

• Grade 8 alloy steel construction for high shear and torsional load resistance
• Cup point geometry bites into mating surfaces to resist axial and rotational movement
• 5-44 UNF fine thread for precise engagement in small-diameter applications
• 1/16 inch internal hex drive for use with standard Allen keys in tight clearances
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional standards
• Headless profile allows fully flush or recessed installation

Compatibility

Designed as a standard-dimension replacement or service fastener for any assembly requiring a 5-44 UNF cup point set screw with a 1/16 inch hex drive, conforming to ASME/ANSI B18.3 specifications.

Installation Notes

Set screws of this type are typically installed by maintenance technicians and mechanical assemblers using a 1/16 inch hex key or Allen wrench. Always de-energize and lock out equipment before accessing any rotating shaft or assembly. Do not overtighten, as the small drive socket is susceptible to rounding under excessive torque. Inspect the seating surface for burrs or debris before installation to ensure full cup point contact.
