Value Collection 101541PR Set Screw 7/16-20 X 7/16 in Cup Point

Product Description

The VALUE COLLECTION 101541PR is a cup point set screw designed for secure, flush fastening applications where a protruding head is not acceptable. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile and torsional strength suitable for demanding industrial and mechanical assembly work. The 7/16-20 UNF thread ensures fine-pitch engagement, and the 7/32-inch hex drive accepts standard hex keys for reliable torque transfer. This set screw meets ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional and material compliance for use in precision assemblies.

This set screw is used in shaft-to-hub connections, collars, pulleys, gears, and similar mechanical assemblies where the fastener must seat below or flush with the mating surface. The cup point bites into the shaft material to resist rotation and axial movement, making it a common choice in light to medium industrial machinery, HVAC equipment drive components, and general fabrication work. Installers requiring fine-thread engagement in high-strength applications will find the Grade 8 alloy construction appropriate for the task.

Key Features

• 7/16-20 UNF fine-thread for precise engagement and strong holding force
• Cup point geometry bites into shaft surface to resist rotation and axial displacement
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 7/32-inch hex drive compatible with standard Allen hex keys
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design allows fully recessed installation in collars, hubs, and housings

Compatibility

Designed as a standard-dimensioned replacement or stock fastener for mechanical assemblies requiring a 7/16-20 UNF cup point set screw with a 7/32-inch hex drive and Grade 8 alloy steel construction per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 7/32-inch hex key or Allen wrench; ensure the key is fully seated before applying torque to avoid rounding the drive. De-energize and lock out all rotating equipment before removing or installing set screws on shafts or hubs. Do not reuse a set screw that shows visible deformation at the cup point or drive socket, as engagement strength may be compromised. Follow applicable machinery safety codes and the equipment manufacturer's assembly specifications for torque guidance.
