Value Collection 601324PR Set Screw 7/16-20 X 2.5in Cup Point

Product Description

The VALUE COLLECTION 601324PR is a cup point set screw designed for mechanical assemblies where a fastener must secure a shaft, collar, or component within a bore without a protruding head. Manufactured from alloy steel, this screw measures 7/16-20 thread size at 2.5 inches in overall length and accepts a 7/32-inch hex key drive. The cup point configuration bites into the mating surface for reliable holding power under vibration and load. Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards. Commonly installed by machinists, millwrights, and maintenance technicians in industrial and mechanical settings.

This set screw is suited for use in shaft collars, pulleys, gears, sprockets, and similar rotating or stationary assemblies where flush or sub-flush fastening is required. The 7/16-20 UNF thread pitch provides fine-thread engagement suitable for applications demanding precise axial positioning and strong clamp load. The cup point is particularly effective on hardened and soft shaft surfaces alike, making this fastener a standard choice across general manufacturing, HVAC equipment assemblies, and mechanical drive systems.

Key Features

• Cup point geometry for reliable surface bite and shaft retention
• 7/16-20 UNF fine thread for precise positioning and strong engagement
• 2.5-inch overall length accommodates deeper bore or collar applications
• 7/32-inch hex key drive for standard Allen wrench installation
• Alloy steel construction for high strength and durability
• Meets ASME/ANSI B18.3 and ASTM F912 standards

Compatibility

Designed as a standard ASME/ANSI B18.3 cup point set screw suitable for any 7/16-20 UNF tapped bore application requiring a hex drive headless fastener.

Installation Notes

Installation requires a properly sized 7/32-inch hex key or Allen wrench. Ensure the mating bore is tapped to 7/16-20 UNF before installation. Shut down and de-energize any rotating equipment fully before inserting or torquing set screws. Do not substitute a mismatched hex key, as rounding the socket will prevent proper tightening and may cause fastener failure.
