Value Collection 601426BR Set Screw 5/8-18x2in Cup Point

Product Description

The VALUE COLLECTION 601426BR is a cup point set screw designed for clamping and positioning applications in mechanical assemblies. It features a 5/8-18 UNF thread and measures 2 inches in overall length. The cup point tip bites into the mating surface to resist rotation and axial movement, making it well suited for securing collars, hubs, gears, and pulleys to shafts. Driven by a 5/16-inch hex key, it is manufactured from alloy steel for high tensile strength and hardness. Meets ASME/ANSI B18.3 and ASTM F912 standards. Weighs approximately 0.02 pounds per piece.

This set screw is used across industrial and mechanical trade applications wherever a flush or recessed fastener is required. Typical installations include motor shaft collars, set collar assemblies, conveyor components, and machinery fixtures. The cup point geometry is preferred when a permanent or semi-permanent grip on a shaft is needed, as the point indents the shaft surface under torque load. Suitable for use by millwrights, maintenance technicians, and mechanical assemblers working on rotating equipment or power transmission components.

Key Features

• Cup point tip provides positive grip by indenting shaft or mating surface under load
• 5/8-18 UNF thread for fine-pitch engagement and precise axial positioning
• 2-inch overall length accommodates deeper hub and collar installations
• 5/16-inch hex drive compatible with standard hex keys and T-handle drivers
• Alloy steel construction delivers high hardness and tensile strength
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards

Compatibility

Designed as a standard 5/8-18 UNF cup point set screw conforming to ASME/ANSI B18.3, compatible with any tapped hole or threaded collar requiring a 5/8-18 fine thread fastener of this point style and length.

Installation Notes

Set screws of this type are typically installed by millwrights or mechanical technicians using a calibrated hex key or T-handle driver. De-energize and lock out all rotating equipment before installation or removal. Apply thread-locking compound if vibration resistance is required. Do not over-drive the cup point beyond the design indent depth, as this can damage shaft surfaces or strip threads.
