Value Collection 601337PR Set Screw 1/2-13 X 4-1/2 in Cup Point

Product Description

The VALUE COLLECTION 601337PR is a cup point set screw designed for secure, load-bearing fastening in mechanical assemblies. This fully threaded headless fastener uses a 1/4-inch hex drive and features a cup point tip that bites into the mating surface to resist rotation and axial movement. The 1/2-13 UNC thread and 4-1/2-inch overall length make it suitable for applications requiring deep thread engagement and strong clamping force. Manufactured from alloy steel, it meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, maintenance mechanics, and industrial technicians install this type of fastener in shafts, collars, pulleys, and similar components.

This set screw is used in mechanical power transmission assemblies where a flush or recessed fastener is required. Typical applications include securing shaft collars, sprockets, gears, and hubs against a rotating shaft. The cup point configuration provides a reliable bite on both hardened and unhardened shaft surfaces. It is well suited for general industrial maintenance, OEM machine assembly, and field repair work where a standard UNC alloy steel set screw is specified.

Key Features

• Cup point tip grips shaft surfaces to prevent rotation and axial slip
• 1/2-13 UNC thread with 4-1/2-inch overall length for deep engagement
• 1/4-inch hex drive accepts standard hex keys and L-wrenches
• Alloy steel construction provides high strength and wear resistance
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design sits flush or below the mating surface

Compatibility

Designed as an OEM-style replacement or standard service fastener for mechanical assemblies requiring a 1/2-13 UNC cup point set screw with a 4-1/2-inch overall length.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a 1/4-inch hex key or L-wrench. De-energize and lock out any rotating machinery before installing or removing set screws. Clean the threaded bore and shaft contact point before installation to ensure full thread engagement. Do not use impact drivers or oversized hex tools, as these can damage the hex socket or strip the threads.
