Value Collection 601422PR Set Screw 5/8-18 X 1-1/2 in Cup Point

Product Description

The VALUE COLLECTION 601422PR is a cup point set screw used to secure components such as collars, pulleys, and gears onto shafts without a protruding head. It features a 5/8-18 UNF thread with an overall length of 1-1/2 inches and is driven by a 5/16-inch hex key. Manufactured from alloy steel to ASTM F912 and ASME/ANSI B18.3 standards, this fastener delivers reliable holding force in demanding mechanical assemblies. The cup point bites into the shaft surface to resist rotational and axial movement. Machinists, millwrights, and maintenance technicians are the typical installers.

This set screw is suited for general industrial, mechanical, and maintenance applications where a flush or recessed fastener is required. Typical uses include locking rotating components on shafts in motors, conveyors, pumps, and similar equipment. The fractional inch sizing and UNF thread make it a common fit in standard inch-dimensioned assemblies. Sold in multiples of 10; individual package quantity is 1 piece.

Key Features

• Cup point geometry bites into shaft material for positive rotational and axial holding
• 5/8-18 UNF thread for use in standard inch-dimensioned assemblies
• 1-1/2 inch overall length provides substantial thread engagement depth
• 5/16-inch hex drive accepts standard hex keys and T-handle drivers
• Alloy steel construction rated to ASTM F912 for high mechanical strength
• Meets ASME/ANSI B18.3 dimensional standards for interchangeability

Compatibility

Designed as a standard ASME/ANSI B18.3 inch-series cup point set screw for use in any application requiring a 5/8-18 UNF headless fastener with a 1-1/2 inch overall length.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/16-inch hex key or Allen driver. De-energize and lock out all equipment before installing or removing set screws on rotating shafts. Ensure mating threads are clean and free of debris before driving the fastener. Do not exceed the torque capacity of the alloy steel fastener by using improvised extensions on the hex key.
