Value Collection 601572BR Cup Point Set Screw 1-1/2-6x4

Product Description

The VALUE COLLECTION 601572BR is a heavy-duty cup point set screw designed for industrial and mechanical fastening applications where a secure, non-permanent hold is required. Manufactured from alloy steel to ASTM F912 and ASME/ANSI B18.3 standards, this fastener measures 1-1/2-6 thread size at 4 inches in overall length. The hex drive accepts a 3/4-inch hex key, providing the torque needed for large-diameter screw engagement. Machinists, millwrights, and maintenance technicians install this fastener where shafts, collars, or mechanical components must be locked in position without a protruding head.

This set screw is suited for use in shaft collars, shaft couplings, pulleys, gears, and similar rotating or stationary assemblies in industrial machinery, HVAC equipment, and mechanical drive systems. The cup point geometry bites into the mating surface to resist rotational and axial movement. The UNC thread form is compatible with standard imperial tapped holes at the 1-1/2-6 pitch. Sold individually, this fastener is appropriate for low-volume repair, maintenance, or custom fabrication work.

Key Features

• Cup point geometry resists axial and rotational movement by biting into the mating shaft surface
• Alloy steel construction meets ASTM F912 material grade requirements for high-strength fastening
• Conforms to ASME/ANSI B18.3 dimensional standards for consistent fit in standard tapped holes
• 3/4-inch hex drive accommodates standard hex keys for high-torque installation
• UNC thread standard at 1-1/2-6 pitch for use with common imperial tapped holes
• Headless design sits flush with or below the mating surface, eliminating snag points

Compatibility

Designed for use in standard 1-1/2-6 UNC tapped holes in shaft collars, couplings, pulleys, and similar mechanical assemblies conforming to ASME/ANSI B18.3 specifications.

Installation Notes

Installation is typically performed by a machinist, millwright, or maintenance mechanic using a 3/4-inch hex key or allen wrench. Ensure the mating shaft and tapped hole are clean and free of debris before installation. De-energize and lock out any machinery before installing or removing set screws in rotating assemblies, following applicable OSHA lockout/tagout procedures. Do not exceed the rated torque range for the fastener grade or use impact tools that may damage the hex socket.
