Value Collection 601038PR Cup Point Set Screw 2-56 X 3/4 in

Product Description

The VALUE COLLECTION 601038PR is a cup point set screw designed for secure, non-permanent fastening in light assemblies and precision mechanical components. Manufactured from alloy steel with a hex drive socket, it is tightened using a hex key and requires no clearance above the fastener surface once fully seated. The cup point geometry bites into the mating surface to resist rotation and axial movement without a protruding head. At 2-56 thread size and 3/4 inches in overall length, this screw is suited for fine-thread applications where compact engagement and positive holding force are required. It conforms to ASME/ANSI B18.3 and ASTM F912 standards.

This set screw is used in applications where a shaft, rod, or component must be locked to a hub, collar, or housing. Typical installations include motor shafts, control knobs, mechanical linkages, and precision instrument assemblies. The 2-56 UNC thread is a fine-pitch, small-diameter size commonly found in instrumentation, HVAC controls, and light electromechanical assemblies. Installation is performed by a machinist, maintenance technician, or mechanical contractor using a 0.035-inch hex key. Minimum order quantity for this item is 10 pieces.

Key Features

• Cup point tip bites into mating shaft or surface for firm axial and rotational hold
• Alloy steel construction provides strength appropriate for small-diameter fastener loads
• Hex socket drive accepts a 0.035-inch hex key for installation in confined spaces
• Headless design sits flush or below the mating surface after installation
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards
• UNC thread standard ensures broad thread gauge compatibility

Compatibility

Designed as a standard-dimension hex socket cup point set screw per ASME/ANSI B18.3, compatible with any tapped 2-56 UNC threaded hole requiring a headless fastener with cup point geometry.

Installation Notes

Installation is performed by a machinist or mechanical technician using a 0.035-inch hex key. Ensure the mating threaded hole is clean and free of debris before driving the screw. Apply thread-locking compound if vibration resistance is required beyond the cup point contact. Avoid overtightening, as alloy steel set screws at this small diameter can be damaged by excessive torque.
