Value Collection 601515BR Set Screw Cup Point Alloy Steel

Product Description

The VALUE COLLECTION 601515BR is a cup point set screw intended for mechanical assemblies where a fastener must apply holding force without a protruding head. It is threaded 1-8 UNC and measures 2-3/4 inches in overall length. The cup point geometry bites into the mating shaft or surface to resist rotation and axial movement. The fastener is manufactured from alloy steel to ASTM F912 and conforms to ASME/ANSI B18.3 dimensional standards. A 9/16-inch hex key drive is used for installation and removal. Machinists, maintenance technicians, and mechanical contractors install this type of fastener in shaft collars, pulleys, gears, and similar rotating or stationary assemblies.

This set screw is suited for use in industrial and commercial mechanical assemblies requiring a headless fastener with reliable axial and rotational holding force. Typical applications include securing hubs, collars, and couplings to keyed or unkeyed shafts. The UNC thread form is standard in North American trade and maintenance environments. It is sold individually and is appropriate for low-volume repair work as well as maintenance stock.

Key Features

• Cup point geometry provides positive bite into mating shaft or surface for reliable hold
• Alloy steel construction meets ASTM F912 material grade requirements
• Conforms to ASME/ANSI B18.3 dimensional standard for hex socket set screws
• 1-8 UNC thread size with 2-3/4 inches overall length
• 9/16-inch hex key drive for installation with standard hex key tools
• Headless design allows flush or below-surface installation

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cup point set screw for use in any mechanical assembly accepting a 1-8 UNC threaded headless fastener.

Installation Notes

Installation requires a 9/16-inch hex key or Allen driver. Ensure the threaded bore is clean and free of debris before threading the fastener in by hand to verify engagement. Power down or de-energize any equipment before servicing rotating assemblies. Do not exceed the torque capacity of the alloy steel fastener or the tapped hole material.
