Value Collection 601149PR Set Screw 8-32 Cup Point Grade 8

Product Description

The VALUE COLLECTION 601149PR is a cup point set screw designed for secure, no-protrusion fastening in mechanical assemblies. It is manufactured from Grade 8 alloy steel, providing high tensile strength suitable for demanding industrial and trade applications. The screw measures 1-3/4 inches in overall length with an 8-32 UNC thread size and is driven by a 5/64 inch hex key. The cup point tip bites into mating surfaces to resist rotation and axial movement. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards. It is commonly installed by machinists, maintenance technicians, and mechanical contractors in shaft collars, pulleys, and gear hubs.

This set screw is suited for light industrial and commercial mechanical assemblies where a flush or recessed fastener is required. Typical applications include securing rotating components to shafts, locking collars in place, and anchoring components in tight spaces where a protruding head would interfere with operation. The 8-32 UNC thread and 1-3/4 inch length make it a practical choice for medium-depth engagement in steel or aluminum assemblies. Minimum order quantity is 5 pieces.

Key Features

• Cup point tip grips mating surfaces to resist rotation and axial displacement
• Grade 8 alloy steel construction for high tensile and hardness ratings
• 8-32 UNC thread for broad compatibility with standard tapped holes
• 5/64 inch hex drive for precise torque application in confined spaces
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design allows fully recessed installation flush with or below the surface

Compatibility

Designed as a standard replacement or stock fastener for any mechanical assembly requiring an 8-32 UNC cup point set screw with a 5/64 inch hex drive and 1-3/4 inch overall length per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance technicians using a 5/64 inch hex key or Allen wrench. Ensure the mating tapped hole is clean and free of debris before threading. De-energize and lock out any equipment before installing or adjusting set screws on rotating shafts or powered assemblies. Avoid over-torquing, which can strip the hex socket or damage the mating surface.
