Value Collection 601352PR Set Screw 1/2-20 X 1-1/4 in Cup Point

Product Description

The VALUE COLLECTION 601352PR is a cup point set screw designed for secure, non-permanent fastening in mechanical assemblies. Manufactured from alloy steel to Grade ASTM F912, this screw features a 1/2-20 UNF thread with an overall length of 1.25 inches. The cup point digs into the mating surface to resist rotation and axial movement without a protruding head. Drive engagement is through a 0.25-inch hex socket. It conforms to ASME/ANSI B18.3 dimensional standards and ASTM F912 material requirements, making it suitable for use in precision mechanical, industrial, and maintenance applications where a flush or recessed fastener is required.

Cup point set screws are widely used in shaft-to-hub connections, collars, pulleys, gears, and similar assemblies across industrial, HVAC, and mechanical maintenance applications. The 1/2-20 UNF thread pitch is a fine-thread specification suited to applications requiring precise clamping force or where vibration resistance is important. This fastener is typically installed by millwrights, maintenance technicians, and mechanical contractors working on rotating equipment and structural assemblies.

Key Features

• Cup point geometry bites into mating surfaces to resist rotation and axial displacement
• 1/2-20 UNF fine thread for precise engagement and vibration resistance
• Alloy steel construction to ASTM F912 for high tensile and torsional strength
• 1/4-inch internal hex drive accepts standard hex keys and hex bit drivers
• Conforms to ASME/ANSI B18.3 dimensional standards
• Headless design sits flush or below surface level for clearance-critical installations

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application requiring a 1/2-20 UNF cup point set screw conforming to ASME/ANSI B18.3 and ASTM F912 standards.

Installation Notes

Installation requires a 1/4-inch hex key or hex bit driver. Power down and de-energize any rotating equipment before servicing shaft-mounted components. Ensure mating surfaces are clean and free of debris before seating the cup point. Follow applicable ASME or equipment manufacturer torque guidelines for the fastener size and material grade.
