Value Collection 601513BR Set Screw Cup Point Alloy Steel

Product Description

The VALUE COLLECTION 601513BR is a cup point set screw designed for secure, reliable fastening in mechanical assemblies. It features a 1-8 UNC thread with an overall length of 2.25 inches and is driven by a 9/16-inch hex key. Manufactured from alloy steel to ASTM F912 material grade, this fastener meets ASME/ANSI B18.3 dimensional standards. The cup point geometry bites into the mating shaft or surface to resist rotation and axial movement under load. Machinists, millwrights, and maintenance technicians install this type of screw in shaft collars, sprockets, pulleys, and similar rotating components.

This set screw is suited for general industrial and mechanical maintenance applications where a headless, flush-mount fastener is required. The UNC thread form is standard in North American manufacturing environments, making this screw a common replacement or stock fastener in fabrication shops, HVAC equipment assemblies, and mechanical drive systems. It is sold individually and is appropriate for both original-equipment and field-service use.

Key Features

• Cup point geometry bites into shaft surface to resist torque and axial displacement
• Alloy steel construction meets ASTM F912 material grade requirements
• Conforms to ASME/ANSI B18.3 dimensional standard for socket set screws
• 1-8 UNC thread form for compatibility with standard North American tapped holes
• 9/16-inch hex drive accepts standard hex keys and T-handle drivers
• Headless profile sits flush or below surface for clearance-critical installations

Compatibility

Designed as a standard ASME/ANSI B18.3 socket set screw for use in any tapped hole with a 1-8 UNC thread requiring a cup point, headless fastener.

Installation Notes

Installation is performed with a calibrated 9/16-inch hex key or Allen-type driver. Always ensure the tapped hole is clean and free of debris before threading the screw. De-energize or lock out any rotating equipment before accessing shaft-mounted components. Do not exceed the torque range appropriate for alloy steel fasteners of this thread size, and verify thread engagement depth meets the requirements of the assembly design.
