Value Collection 601020PR Set Screw 1-72 X 5/32 in Cup Point

Product Description

The VALUE COLLECTION 601020PR is a cup point set screw designed for precision fastening applications in mechanical assemblies. Manufactured from alloy steel to the ASTM F912 material grade and conforming to ASME/ANSI B18.3, this screw measures 1-72 thread size by 5/32 inches in overall length. It is driven by a hex key with a 0.028 inch key size, making it compatible with standard Allen wrenches. The cup point tip bites into mating surfaces to resist rotation and axial movement without the use of a through-hole. Machinists, millwrights, and maintenance technicians install this fastener in collars, pulleys, gears, and similar components on precision shafting.

This set screw is suited for light-duty precision assemblies where a fine unified thread and compact profile are required. The 1-72 UNF thread standard indicates a fine-pitch designation, providing superior holding strength relative to fastener diameter. Typical applications include instrument mechanisms, small motor assemblies, optical equipment, and other applications demanding tight tolerances and secure locking without protruding hardware.

Key Features

• Cup point geometry bites into shaft surface for positive rotational and axial hold
• 1-72 UNF fine-pitch thread for high thread engagement in thin-walled components
• Alloy steel construction rated to ASTM F912 for consistent mechanical performance
• Conforms to ASME/ANSI B18.3 dimensional standard for interchangeability
• Hex socket drive accepts a 0.028 inch hex key for precise torque application in confined spaces
• 5/32 inch overall length suits shallow boss and hub installations

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cup point set screw in 1-72 UNF thread, suitable for use wherever this thread size and point style are specified in mechanical assemblies.

Installation Notes

Install and remove using a hex key that matches the 0.028 inch drive size to avoid rounding the socket. Always de-energize or lock out machinery before accessing rotating components such as shafts, collars, or pulleys. Ensure mating threads are clean and free of debris before driving the screw. Follow applicable machine safety standards and equipment manufacturer torque guidelines when securing precision assemblies.
