Value Collection 601033PR Cup Point Set Screw 2-56 X 3/8 in

Product Description

The VALUE COLLECTION 601033PR is a cup point set screw designed for precision clamping and locking applications in mechanical assemblies. Manufactured from alloy steel, this headless fastener is driven with a hex key and seats its cup point into a mating surface to resist rotational and axial movement on shafts, collars, and similar components. It carries an overall length of 3/8 inches and is threaded to a 2-56 UNC specification. Conforming to ASME/ANSI B18.3 and ASTM F912 standards, this screw is suited for tight-clearance installations where a protruding head is not acceptable. Machinists, maintenance technicians, and mechanical assemblers install this type of fastener routinely in production and field service environments.

This set screw is appropriate for light-duty shaft-to-hub locking, dial and knob retention, and precision instrument or machine component assembly where a flush or recessed fastener is required. The 2-56 UNC thread size targets small-bore applications common in instrumentation, electronics enclosures, and fine mechanical assemblies. It is sold in multiples of 100 pieces per order, with a package quantity of 1.

Key Features

• Cup point geometry bites into the mating surface for secure hold against rotation and axial shift
• Alloy steel construction provides strength appropriate for general mechanical fastening
• Hex socket drive accommodates a 0.035 inch hex key for installation in recessed or tight clearance locations
• Headless design sits flush or below the surface, eliminating protrusion hazards
• Meets ASME/ANSI B18.3 and ASTM F912 standards for dimensional and mechanical conformance
• 2-56 UNC thread standard ensures compatibility with precision small-bore tapped holes

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for applications requiring a 2-56 UNC cup point set screw to ASME/ANSI B18.3 or ASTM F912 specification.

Installation Notes

Installation requires a 0.035 inch hex key; use a calibrated torque driver where the application specifies a controlled clamp load. Ensure the mating shaft or surface is clean and free of burrs before seating the cup point. Do not overtighten, as the small thread size is susceptible to galling and thread stripping. Minimum order quantity is 100 pieces — verify order multiples before purchasing.
