Value Collection 101613BR Set Screw 5/8-11 X 1/2 in Cup Point

Product Description

The VALUE COLLECTION 101613BR is a cup point set screw designed for secure shaft-to-hub and collar-to-shaft fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to loosening under load and vibration. It features a 5/8-11 UNC thread with an overall length of 0.5 inches and is driven by a 5/16-inch hex key. The cup point geometry bites into the mating surface to resist rotational and axial movement without requiring a nut or through-hole. Conforms to ASME/ANSI B18.3 and ASTM F912 standards. Suitable for maintenance technicians, millwrights, and industrial mechanics working on shafts, collars, pulleys, and sprockets.

This set screw is commonly used in industrial and commercial mechanical assemblies where a headless fastener is required to lock a component onto a shaft. Typical applications include motor shafts, drive collars, shaft couplings, and pump assemblies across HVAC, light manufacturing, and general mechanical service environments. The cup point is the standard choice when a permanent or semi-permanent bite into the shaft surface is acceptable. Minimum order quantity is 10 pieces.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cup point geometry bites into shaft surface to resist rotation and axial movement
• 5/8-11 UNC thread for compatibility with standard inch-series tapped holes
• 5/16-inch hex drive accepts standard hex keys and T-handle drivers
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design sits flush or below surface when fully seated

Compatibility

Designed as a standard ASME/ANSI B18.3 inch-series cup point set screw suitable for any 5/8-11 UNC tapped hole application requiring a headless fastener.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen driver. Ensure the tapped hole is clean and free of debris before threading. Torque to the fastener specification appropriate for Grade 8 alloy steel at this thread size per applicable mechanical standards. De-energize and lock out any rotating equipment before servicing shaft collars or drive components.
