Value Collection 101415PR Set Screw 5/16-24 X 5/8 in Cup Point

Product Description

The VALUE COLLECTION 101415PR is a cup point set screw designed for secure, reliable shaft-to-hub and collar locking in mechanical assemblies. Manufactured from Grade 8 alloy steel, it delivers high tensile strength and resistance to loosening under load. The screw measures 5/16-24 thread size by 5/8 inches in overall length and is driven by a 5/32-inch hex key. The cup point geometry bites into the mating surface to resist rotation and axial movement. Machinists, millwrights, and maintenance technicians routinely install this fastener in precision assemblies where a flush or recessed seating point is required.

This set screw is suited for use in light-to-medium industrial applications including shaft collars, shaft couplings, pulleys, sprockets, and mechanical gearsets. The unified fine thread (UNF) 5/16-24 profile provides greater thread engagement per unit length compared to coarse thread, making it a preferred choice in applications with limited thread depth or where vibration resistance is critical. It conforms to ASME/ANSI B18.3 and ASTM F912 standards, ensuring dimensional and mechanical consistency across production and maintenance operations.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cup point tip bites into mating surface to resist axial and rotational movement
• 5/16-24 UNF thread for enhanced engagement in fine-thread applications
• 5/32-inch hex drive compatible with standard Allen keys and hex drivers
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• Minimum order quantity of 100 pieces per order

Compatibility

Designed as a standard 5/16-24 UNF cup point set screw for use in any mechanical assembly requiring a Grade 8 alloy steel fastener of this thread size and length.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/32-inch hex key or Allen driver. Ensure the mating shaft or hub surface is clean and free of burrs before tightening. Apply only the recommended torque for a 5/16-24 Grade 8 set screw as specified in relevant fastener torque references. Avoid overtightening, which can deform the cup point or damage the shaft surface.
