Value Collection 601203PR Set Screw 12-24 X 1/2 in Cup Point

Product Description

The VALUE COLLECTION 601203PR is a cup point set screw designed for mechanical fastening applications where a headless, flush-mount profile is required. Threaded 12-24 UNC with an overall length of 1/2 inch, this screw uses a 7/64 inch hex drive and features a cup point tip that bites into mating surfaces to resist rotational and axial movement. Manufactured from alloy steel to ASTM F912 and conforming to ASME/ANSI B18.3, it delivers reliable holding strength under vibration and load. Machinists, millwrights, and maintenance technicians install this type of fastener in shaft collars, pulleys, gears, and similar rotating components.

Cup point set screws in the 12-24 thread size are widely used in light-duty to medium-duty mechanical assemblies across HVAC equipment, motors, pumps, and general industrial machinery. The cup point geometry provides positive engagement with the mating surface without requiring a through-hole, making it suitable for set-screw hubs, setscrewed couplings, and adjustable collars in both residential and commercial service applications.

Key Features

• Thread size 12-24 UNC for broad compatibility with standard tapped holes
• Cup point tip provides strong rotational and axial grip on shafts and mating surfaces
• 7/64 inch hex drive accepts standard hex keys and allen wrenches
• Alloy steel construction rated to ASTM F912 for enhanced strength and hardness
• Conforms to ASME/ANSI B18.3 dimensional standard
• Headless profile sits flush or below surface level for clearance-sensitive installations

Compatibility

Designed as a standard ASME/ANSI B18.3 cup point set screw suitable for any 12-24 UNC tapped hole application requiring a headless alloy steel fastener.

Installation Notes

Installation is performed with a 7/64 inch hex key; power down or de-energize any equipment before accessing rotating shaft assemblies. Ensure the mating surface is clean and the tapped hole is free of debris before driving the screw. Do not exceed the torque capacity of the alloy steel grade for the thread size being used. Follow applicable machinery safety standards and equipment manufacturer guidelines during assembly and service.
