Value Collection 101629BR Set Screw 5/8-11 X 2 in Cup Point

Product Description

The VALUE COLLECTION 101629BR is a cup point set screw designed for mechanical assemblies where a fastener must apply clamping or locking force without protruding above the surface. Sized at 5/8-11 UNC thread by 2 inches overall length, this headless fastener seats fully within a tapped hole and drives with a 5/16-inch hex key. It is manufactured from Grade 8 alloy steel, which provides the high tensile strength needed for demanding shaft-to-collar and pulley-locking applications. The cup point geometry bites into the mating surface to resist rotational movement. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards.

This set screw is suited for use in industrial and mechanical maintenance applications, including shaft collars, sprockets, gears, pulleys, and similar components where a flush, non-protruding fastener is required. Maintenance technicians, millwrights, and machinists encounter this size regularly in both light and heavy industrial equipment. It is appropriate for any setting that calls for a standard UNC coarse-thread headless fastener at this diameter and length combination. Minimum order quantity is 10 pieces.

Key Features

• 5/8-11 UNC coarse thread provides broad compatibility with standard tapped holes at this diameter
• Cup point geometry bites into shaft or mating surface to resist axial and rotational movement
• Grade 8 alloy steel construction delivers high tensile and proof load strength
• 5/16-inch hex drive allows use with standard hex keys and Allen wrenches
• Headless design seats flush within the tapped hole, eliminating protrusion hazards
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards

Compatibility

Designed as a standard 5/8-11 UNC cup point set screw for use in any application requiring an ASME/ANSI B18.3 compliant headless fastener at this thread size and length.

Installation Notes

Installation is performed with a 5/16-inch hex key; ensure the key is fully seated in the drive socket before applying torque to avoid rounding. Secure the workpiece and de-energize or lock out any machinery before installing or removing set screws in rotating components, following applicable OSHA lockout/tagout procedures. Do not reuse a set screw that shows signs of deformation at the cup point or damaged threads, as this can compromise holding force.
