Value Collection 601046PR Set Screw 2-64 X 3/16 in Cup Point

Product Description

The VALUE COLLECTION 601046PR is a cup point set screw designed for precision fastening applications in mechanical assemblies. Manufactured from alloy steel to ASTM F912 material grade and conforming to ASME/ANSI B18.3, this screw provides reliable holding force without a protruding head. The 2-64 UNF thread and 3/16-inch overall length make it suited for small-diameter, fine-pitch applications where space is limited. Drive engagement is via a hex key socket measuring 0.0350 inches, allowing controlled torque in tight clearances. Machinists, millwrights, and mechanical technicians commonly install these in collars, hubs, and shaft retention applications.

This set screw is appropriate for light industrial and precision mechanical assemblies where a flush or recessed fastener is required. The cup point geometry bites into a shaft surface to resist rotational and axial movement, making it a standard choice for shaft-to-collar retention in motors, pulleys, and gear assemblies. The fine 2-64 UNF thread pitch supports accurate depth adjustment and reduces the risk of loosening under vibration. This part is sold individually with a minimum order quantity of 10 units.

Key Features

• Cup point geometry provides firm bite into shaft surfaces for positive retention
• 2-64 UNF fine thread for precise depth control and vibration resistance
• Alloy steel construction to ASTM F912 material grade for strength and durability
• Hex socket drive at 0.0350 inches for use with standard hex keys in confined spaces
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design allows fully recessed installation flush with or below the mating surface

Compatibility

Designed as a standard-dimension replacement or stock set screw for mechanical assemblies requiring a 2-64 UNF thread, 3/16-inch overall length, cup point, and hex socket drive conforming to ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists or mechanical technicians using a hex key or hex driver sized to 0.0350 inches. Always ensure the mating threaded hole is clean and free of debris before driving the screw. De-energize and lock out any rotating equipment before accessing shaft collars or hubs. Avoid over-driving, which can strip the fine 2-64 thread or deform the cup point.
