Value Collection 101019PR Set Screw 1-72 X 1/16 in Cup Point

Product Description

The VALUE COLLECTION 101019PR is a Grade 8 alloy steel set screw sized 1-72 x 1/16 inch overall length, featuring a cup point tip and hex socket drive. Set screws of this type are fully threaded, headless fasteners used to secure a component — such as a collar, gear, or pulley — against a shaft by biting into or pressing against its surface. The cup point concentrates clamping force into a small ring contact area, providing reliable resistance to rotational and axial movement. Installation requires a 0.0280 inch hex key. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards.

This set screw is suited for light-duty mechanical assemblies where precise, low-profile fastening is required. The 1-72 thread size (UNF) is a fine-pitch designation common in miniature and instrument-grade applications including small motors, optical mounts, instrumentation hardware, and precision mechanical components. Alloy steel construction with Grade 8 material rating provides elevated tensile and torsional strength relative to standard carbon steel fasteners. Sold in a minimum order quantity of 100 pieces per order, with a package quantity of 1.

Key Features

• Cup point tip concentrates holding force to resist shaft rotation and axial shift
• Grade 8 alloy steel provides high tensile strength for demanding mechanical applications
• Fine-pitch 1-72 UNF thread for secure engagement in miniature threaded bores
• Hex socket drive (0.0280 inch key) for precise torque application in tight spaces
• Manufactured to ASME/ANSI B18.3 and ASTM F912 fastener standards
• Fully headless profile sits flush or below surface for clearance-critical assemblies

Compatibility

Designed as an OEM-style replacement or standard-supply set screw for miniature mechanical assemblies requiring a 1-72 UNF threaded, cup-point, hex-socket fastener meeting ASME/ANSI B18.3 and ASTM F912 specifications.

Installation Notes

Installation is typically performed by mechanical technicians or millwrights using a calibrated 0.0280 inch hex key. Ensure the mating threaded bore is clean and free of debris before driving the screw. Do not exceed the rated torsional capacity of the fastener by using excessive key leverage or power tools without torque limiting. Follow applicable ASME standards for fastener installation in the target assembly.
