Value Collection 101539PR Set Screw 7/16-20 X 3/8 in Cup Point

Product Description

The VALUE COLLECTION 101539PR is a Grade 8 alloy steel cup point set screw designed for secure, load-bearing fastening applications in mechanical assemblies. With a 7/16-20 UNF thread size and an overall length of 3/8 inches, this fastener delivers the holding strength and hardness required in high-stress installations. The 7/32-inch internal hex drive accepts a standard hex key for installation and removal. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, this screw meets dimensional and mechanical requirements expected by maintenance technicians and machine builders working with precision equipment.

This set screw is used in mechanical and industrial assemblies where a cup point is needed to grip a shaft or mating surface without a protruding head. Typical applications include collars, pulleys, gears, and shaft-mounted components in HVAC equipment, pumps, motors, and general mechanical systems. The cup point digs into the shaft surface to resist rotation and axial movement. Minimum order quantity is 100 pieces, making this suitable for shop stock, maintenance inventories, and production line use.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cup point geometry bites into shaft material to resist loosening under vibration
• 7/32-inch hex drive accepts standard hex keys and ball-end drivers
• 7/16-20 UNF thread for fine-thread engagement and precise torque control
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• Headless design sits flush or below surface for clearance-critical assemblies

Compatibility

Designed as a standard UNF set screw for use in any 7/16-20 threaded hole requiring a cup point, headless fastener per ASME/ANSI B18.3 specification.

Installation Notes

Installation is performed with a 7/32-inch hex key or Allen driver. Ensure the mating threaded hole is clean and free of debris before driving the screw. Power down any rotating equipment and lock out energy sources before servicing shaft-mounted components. Do not exceed the recommended seating torque range for Grade 8 alloy steel set screws as defined in the applicable ASME standard.
