Value Collection 601327PR Set Screw 1/2-13 X 2-1/4 in Cup Point

Product Description

The VALUE COLLECTION 601327PR is a cup point set screw designed for secure, non-permanent fastening in mechanical assemblies where a strong holding force against a shaft or mating surface is required. Manufactured from alloy steel, this fastener measures 1/2-13 thread size by 2-1/4 inches in overall length and is driven with a 1/4-inch hex key. The cup point geometry bites into the mating surface to resist rotation and axial movement. It conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it suitable for demanding industrial and mechanical applications. Licensed tradespeople and mechanical assemblers working on shafts, collars, pulleys, and similar components will find this fastener a reliable choice.

This set screw is appropriate for use in a wide range of mechanical and industrial settings, including HVAC equipment assemblies, motor shaft collars, pulley and sprocket retention, and general machine shop applications. Its UNC thread form is the standard for inch-based fastening in North American equipment. The alloy steel construction provides the hardness and shear strength needed for moderate-to-heavy duty holding applications in both commercial and light industrial environments.

Key Features

• Cup point geometry provides strong grip and resistance to rotation on shafts and collars
• Alloy steel construction delivers hardness and shear strength for demanding applications
• 1/2-13 UNC thread for compatibility with standard inch-based hardware
• 2-1/4-inch overall length suits deeper engagement requirements
• 1/4-inch hex key drive for standard Allen wrench installation
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed for use in any mechanical assembly requiring a 1/2-13 UNC threaded set screw with cup point and 1/4-inch hex drive, conforming to ASME/ANSI B18.3 and ASTM F912 specifications.

Installation Notes

Installation is performed using a 1/4-inch hex key or Allen wrench. De-energize and lock out any equipment before installing or adjusting set screws on rotating components such as shafts or pulleys. Do not exceed the rated torque range for the fastener size and material grade. Verify thread engagement and seating before returning the assembly to service.
