Value Collection 601201PR Set Screw 12-24 X 3/8 in Cup Point

Product Description

The VALUE COLLECTION 601201PR is a cup point set screw designed for mechanical assemblies where a fastener must seat flush or below the surface of a workpiece. Manufactured from alloy steel to ASTM F912 grade, this screw delivers the hardness and shear strength required for shaft-to-hub locking, collar positioning, and similar holding applications. The 7/64 inch hex drive accepts a standard hex key for installation in tight or recessed access points. Conforming to ASME/ANSI B18.3, this fastener meets recognized dimensional and mechanical property standards used across industrial and trade applications.

This set screw is suited for use in motors, pulleys, couplings, collars, and other rotating or stationary assemblies found in HVAC equipment, pumps, and general mechanical systems. The cup point geometry bites into the mating surface, providing positive grip and resistance to loosening under vibration. It is appropriate for both residential and light commercial mechanical work wherever a UNC thread, fractional-inch set screw is specified.

Key Features

• Cup point geometry for firm bite and vibration resistance against mating shaft surfaces
• Alloy steel construction rated to ASTM F912 for high hardness and load capacity
• 7/64 inch hex drive compatible with standard hex keys and ball-end drivers
• UNC thread standard ensures broad compatibility with standard tapped holes
• Conforms to ASME/ANSI B18.3 dimensional standards
• Headless design seats fully recessed to avoid interference with adjacent components

Compatibility

Designed as an OEM-style replacement or general-use set screw for any mechanical assembly specifying a 12-24 UNC, 3/8 inch overall length, cup point fastener conforming to ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation is typically performed by a mechanic, millwright, or HVAC technician using a 7/64 inch hex key or T-handle driver. Ensure the mating shaft or bore is clean and free of debris before seating the screw. De-energize and lock out any equipment before tightening set screws on rotating shafts. Do not exceed the torque capacity of the alloy steel fastener by using extension bars or power tools without proper torque control.
