Value Collection 601580BR Cup Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 601580BR is a cup point set screw designed for secure, flush-style fastening in mechanical assemblies where a protruding fastener head is not acceptable. Manufactured from alloy steel to the ASTM F912 material grade, this screw meets ASME/ANSI B18.3 dimensional standards. The thread size is 1-1/8-7 UNC with an overall length of 2.5 inches, and it is driven by a 9/16-inch hex key. Cup point set screws are used to lock components such as collars, pulleys, gears, and hubs onto shafts by biting into the shaft surface under tightening load. Licensed tradespeople and maintenance mechanics install this fastener in industrial, HVAC, and mechanical equipment applications.

This set screw is suited for use in medium-to-heavy-duty mechanical assemblies where a coarse UNC thread form is required. Common applications include shaft-collar locking, gear and sprocket retention, and positioning of rotating components in industrial equipment. The coarse 1-1/8-7 thread pitch provides reliable engagement in standard threaded bores without fine-pitch thread preparation. Each package contains one piece, making it practical for single-unit replacement or repair work on specific assemblies.

Key Features

• Cup point tip bites into shaft surface for positive no-slip retention under load
• Alloy steel construction meets ASTM F912 material grade for strength in demanding applications
• Coarse 1-1/8-7 UNC thread form for reliable engagement in standard bores
• 9/16-inch hex drive accepts standard hex keys and hex socket tooling
• Conforms to ASME/ANSI B18.3 dimensional standards for consistent fitment
• Headless design allows fully flush or below-surface installation

Compatibility

Designed as an OEM-style replacement or maintenance fastener for any threaded bore or tapped hole requiring a 1-1/8-7 UNC cup point set screw conforming to ASME/ANSI B18.3 and ASTM F912 standards.

Installation Notes

Installation is performed by mechanics and millwrights using a 9/16-inch hex key or T-handle hex driver. Always de-energize and lock out rotating equipment before removing or installing shaft-retention fasteners. Verify that the mating threaded bore is clean and free of debris before threading the screw in. Do not exceed the rated tightening torque for the alloy steel grade, and consult applicable equipment service documentation for torque requirements.
