Value Collection 601424BR Set Screw 5/8-18 X 1-3/4 in Cup Point

Product Description

The VALUE COLLECTION 601424BR is a cup point set screw designed for secure, flush fastening in mechanical assemblies. It features a 5/8-18 UNF thread and measures 1-3/4 inches in overall length. The cup point digs into the mating surface to resist rotation and axial movement without a protruding head. Driven by a 5/16-inch hex key, the alloy steel construction provides the tensile strength needed in high-load applications. This screw meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians working on shafts, collars, pulleys, and similar mechanical components are the typical installers.

This set screw is suited for use in industrial and commercial mechanical assemblies where a headless fastener is required to lock components onto shafts or within bores. The 5/8-18 UNF thread is a fine-pitch specification commonly found in precision shaft-locking applications across manufacturing, HVAC equipment, pump assemblies, and power transmission components. The cup point style is the most widely used point geometry for general-purpose shaft retention.

Key Features

• 5/8-18 UNF fine-pitch thread for precise shaft engagement
• Cup point geometry bites into shaft surface to resist rotation and axial shift
• Alloy steel construction for high tensile and torsional strength
• 5/16-inch hex drive compatible with standard hex keys and T-handle drivers
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits flush or below surface for clearance-sensitive applications

Compatibility

Designed as a standard headless cup point set screw for use in mechanical assemblies requiring a 5/8-18 UNF threaded fastener with a 5/16-inch hex drive.

Installation Notes

Installation requires a calibrated 5/16-inch hex key or Allen driver. Always de-energize and lock out equipment before servicing any shaft or rotating assembly. Verify thread engagement depth and confirm the cup point seats fully against the shaft surface before applying final torque. Alloy steel set screws should not be used in applications requiring corrosion resistance without appropriate protective coatings or material substitution.
