Value Collection 601044PR Set Screw 2-64 X 1/8 in Cup Point

Product Description

The VALUE COLLECTION 601044PR is a cup point set screw designed for precision fastening applications in mechanical assemblies. This screw uses a 2-64 UNF thread and measures 1/8 inch in overall length. It is driven with a hex key and seats against a shaft or surface with a cup point tip that bites into the mating material to resist rotation and axial movement. Manufactured from alloy steel to ASTM F912 and dimensioned to ASME/ANSI B18.3, this fastener is suited for machine shops, equipment repair facilities, and trade professionals who need a small, high-strength set screw for close-tolerance work.

This set screw is used in residential and commercial mechanical assemblies where a low-profile, headless fastener is required to secure a component to a shaft or within a bore. Common applications include motor shaft collars, gear hubs, valve handles, and instrumentation hardware. The fine 2-64 UNF thread pitch provides precise engagement in thin-walled or miniature threaded holes. Electricians, HVAC technicians, and mechanical contractors working on small-shaft motor assemblies or fan wheel hubs will find this size applicable for OEM-style replacement fastening tasks.

Key Features

• Cup point tip bites into mating shaft surface to resist both rotational and axial movement
• 2-64 UNF fine thread for precise engagement in close-tolerance tapped holes
• Alloy steel construction meets ASTM F912 material grade requirements
• Dimensioned to ASME/ANSI B18.3 for consistent fit with standard hex keys
• Driven with a 0.035 inch hex key for access in tight or recessed locations
• Headless design sits flush or below the surface of the mating part

Compatibility

Designed as an OEM-style replacement or maintenance stock fastener for any mechanical assembly using a 2-64 UNF tapped hole requiring a headless cup point set screw per ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists, millwrights, or qualified trade technicians using a 0.035 inch hex key. De-energize and lock out any equipment before servicing shaft-mounted components. Do not exceed the torque capacity of the 2-64 thread by over-driving the fastener, as the small thread form is susceptible to stripping. Confirm the tapped hole thread standard is UNF before installation to ensure proper engagement.
