Value Collection 601570BR Set Screw 1-1/2-6 X 3-1/2 in Cup Point

Product Description

The VALUE COLLECTION 601570BR is a heavy-duty cup point set screw designed for high-load clamping and locking applications in mechanical assemblies. Manufactured from alloy steel to ASTM F912 and ASME/ANSI B18.3 standards, this screw measures 1-1/2-6 UNC thread by 3-1/2 inches overall length. The cup point geometry bites into mating surfaces to resist rotation and axial movement under sustained load. A 3/4-inch hex key drive provides the torque input needed for large-diameter fastener installation. This size is typically specified by machinists, millwrights, and maintenance technicians working on heavy industrial equipment, shaft collars, or power transmission components.

This set screw is suited for industrial and commercial applications where a large-diameter, coarse-thread fastener is required. Typical uses include securing hubs, collars, pulleys, and gears to shafts in rotating machinery. The cup point is well-suited for installations where the screw must indent a soft or hardened shaft surface to maintain a secure, non-slip hold under vibration and dynamic loads. Installations are common in plant maintenance, machine shops, and heavy equipment service environments.

Key Features

• Cup point geometry indents mating surfaces for positive locking under vibration and dynamic loads
• Alloy steel construction for high tensile strength and resistance to shear forces
• Meets ASTM F912 and ASME/ANSI B18.3 dimensional and material standards
• 1-1/2-6 UNC coarse thread for fast engagement and reliable clamp load in large-diameter applications
• 3/4-inch hex key (internal hex) drive for high-torque installation with standard hex keys or allen wrenches
• 3-1/2 inches overall length provides deep thread engagement for maximum holding power

Compatibility

Designed as a standard replacement or maintenance fastener for industrial assemblies requiring a 1-1/2-6 UNC cup point set screw conforming to ASME/ANSI B18.3 and ASTM F912 specifications.

Installation Notes

Installation is typically performed by machinists or millwrights using a calibrated hex key or T-handle driver sized to 3/4 inch. Ensure the receiving tapped hole is clean, free of debris, and correctly threaded to 1-1/2-6 UNC before installation. De-energize and lock out all rotating machinery before installing or removing set screws per applicable OSHA lockout/tagout procedures. Do not exceed the rated torque capacity of the drive tool or the mating tapped hole.
