Value Collection 601509BR Cup Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 601509BR is a cup point set screw designed for secure fastening applications where a headless, flush-mount fastener is required. Sized at 1-8 UNC thread with an overall length of 1-1/4 inches, this screw is manufactured from alloy steel to ASTM F912 and ASME/ANSI B18.3 standards. It is driven with a 9/16-inch hex key and features a cup point tip that bites into a shaft or mating surface to resist rotation and axial movement. This fastener is a standard choice for machinists, millwrights, and maintenance technicians working with pulleys, collars, gears, and similar shaft-mounted components.

The 601509BR is suited for use in general industrial, manufacturing, and maintenance applications. Cup point set screws in this size range are commonly installed in shaft collars, shaft couplings, set-collar assemblies, and machine components where positive retention of rotating or sliding parts is needed. The 1-8 UNC coarse thread provides good thread engagement in steel and cast iron housings.

Key Features

• Cup point tip digs into shaft surface for positive grip and axial retention
• 1-8 UNC coarse thread for strong engagement in steel and iron components
• Alloy steel construction meets ASTM F912 material grade requirements
• Conforms to ASME/ANSI B18.3 dimensional standards for hex socket set screws
• 9/16-inch hex drive socket for standard hex key installation
• Overall length of 1-1/4 inches suits medium-depth collar and hub applications

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cup point set screw for use in shaft collars, shaft couplings, pulleys, gears, and similar components requiring a 1-8 UNC threaded fastener.

Installation Notes

Installation is performed with a 9/16-inch hex key or T-handle driver. Before installation, ensure the shaft and collar bore are clean and free of debris. Always de-energize or lock out machinery before working on rotating shaft components in accordance with applicable LOTO procedures. Tighten to the appropriate torque for the application and inspect seating of the cup point against the shaft surface.
