Value Collection 601259PR Set Screw 5/16-24 X 1-3/4 in Cup Point

Product Description

The VALUE COLLECTION 601259PR is a cup point set screw designed for secure shaft-to-hub and collar locking applications in mechanical assemblies. It features a 5/16-24 UNF thread with an overall length of 1-3/4 inches and is driven by a 5/32 inch hex key. The cup point geometry bites into the mating surface to resist rotation and axial movement under load. Manufactured from alloy steel, it meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians use these fasteners when assembling pulleys, sprockets, collars, and similar power-transmission components.

Cup point set screws like the 601259PR are used across industrial and commercial mechanical applications where a headless fastener is required to avoid interference with adjacent moving parts. Common install scenarios include securing shaft collars on conveyor systems, mounting pulleys on motor shafts, and fixing knobs or dials in equipment assemblies. The fine 5/16-24 UNF thread pitch provides precise engagement and strong holding force in steel and cast-iron bores. This fastener is sold individually but requires a minimum order quantity of 10 pieces per order.

Key Features

• Cup point tip bites into shaft surface for positive resistance to rotation and axial shift
• 5/16-24 UNF fine thread for precise engagement and high clamping force
• 1-3/4 inch overall length suits deeper bore and thicker collar applications
• 5/32 inch hex drive accepts standard hex keys and T-handle hex drivers
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F912 standards
• Headless design eliminates protrusion hazard in rotating-shaft assemblies

Compatibility

Designed as a standard replacement or stocking fastener for mechanical assemblies requiring a 5/16-24 UNF cup point set screw with a 5/32 inch hex drive, conforming to ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 5/32 inch hex key or T-handle driver. Ensure the shaft and bore threads are clean and free of debris before installation. De-energize and lock out all equipment before servicing any shaft or rotating assembly per applicable OSHA lockout/tagout procedures. Do not exceed the torque capacity of the alloy steel material by using impact tools or extension handles on the hex key.
