Value Collection 601403BR Set Screw 5/8-11 X 5in Cup Point

Product Description

The VALUE COLLECTION 601403BR is a cup point set screw designed for mechanical assemblies where a fastener must seat flush within a tapped hole and apply direct holding force to a shaft or mating surface. This screw measures 5/8-11 thread size by 5 inches overall length, features a 5/16-inch hex drive, and is manufactured from alloy steel to Grade ASTM F912. The cup point geometry bites into the shaft surface to resist rotational and axial movement. It is installed by machinists, millwrights, and maintenance technicians working on drive assemblies, pulleys, collars, and similar mechanical components.

This set screw is suited for industrial and commercial mechanical applications where a UNC-threaded, hex-drive fastener is required. Typical use cases include locking shaft collars, securing pulleys or sprockets to shafts, and fixing mechanical components in position within rotating assemblies. The ASME/ANSI B18.3 standard governs its dimensional requirements, and the ASTM F912 grade defines its mechanical properties. Sold individually, it is appropriate for maintenance repair and original equipment assembly work.

Key Features

• Cup point tip engages shaft surface for strong axial and rotational resistance
• 5/8-11 UNC thread for compatibility with standard tapped holes
• 5-inch overall length accommodates deep-set or extended-reach applications
• 5/16-inch hex drive for standard hex key or T-handle installation
• Alloy steel construction, Grade ASTM F912, for high strength in mechanical service
• Meets ASME/ANSI B18.3 dimensional standard

Compatibility

Designed as a standard UNC set screw for use in any tapped 5/8-11 threaded hole requiring a cup point, hex-drive fastener per ASME/ANSI B18.3.

Installation Notes

Installation is typically performed by a machinist, millwright, or maintenance technician using a 5/16-inch hex key or Allen wrench. De-energize and lock out any equipment before installing or removing set screws in rotating assemblies, per standard LOTO procedures. Do not exceed the torque rating specified by the equipment manufacturer for 5/8-11 fasteners. Inspect threads for damage before installation and ensure the tapped hole is clean and free of debris.
