Value Collection 601199PR Set Screw 12-24 X 5/16 in Cup Point

Product Description

The VALUE COLLECTION 601199PR is a cup point set screw designed for mechanical fastening applications where a headless, flush-mount fastener is required. Sized at 12-24 UNC thread with an overall length of 5/16 inches, this set screw is manufactured from alloy steel to meet ASTM F912 material grade requirements. It is driven with a 7/64 inch hex key and conforms to the ASME/ANSI B18.3 fastener standard. The cup point geometry bites into the mating shaft or surface to resist rotation and axial movement without requiring a through-hole. Machinists, millwrights, and maintenance technicians routinely stock this size for motor shaft collars, shaft couplings, set collars, and similar assemblies.

This set screw is suited for light- to medium-duty mechanical assemblies in industrial, commercial, and trade service environments. Common applications include securing pulleys, gears, knobs, and shaft collars to rotating shafts. The 12-24 UNC thread size is a standard fractional-inch coarse thread widely used in HVAC blower assemblies, pump components, and general mechanical equipment found in both residential and commercial installations.

Key Features

• Cup point geometry bites into mating surface to resist shaft rotation and axial displacement
• 12-24 UNC coarse thread for reliable engagement in standard tapped holes
• Alloy steel construction meeting ASTM F912 material grade requirements
• Conforms to ASME/ANSI B18.3 fastener standard for dimensional consistency
• 7/64 inch internal hex drive for use with standard hex keys and Allen wrenches
• Headless design allows full flush or sub-flush installation in tapped bores

Compatibility

Designed as an OEM-style replacement or maintenance stock fastener for any mechanical assembly requiring a 12-24 UNC cup point set screw conforming to ASME/ANSI B18.3 and ASTM F912 specifications.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated hex key or T-handle driver sized at 7/64 inch. De-energize and lock out all rotating equipment before removing or installing set screws in shaft assemblies. Ensure the tapped hole is clean and free of debris before threading the fastener. Do not overtighten, as alloy set screws can shear if torque is applied beyond the rated capacity of the thread size.
