Value Collection 101040PR Set Screw 2-56 X 3/32 in Cup Point

Product Description

The VALUE COLLECTION 101040PR is a cup point set screw designed for secure, vibration-resistant fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, this screw features a hex drive and a cup point that bites into the mating surface to resist rotation and axial movement. The 2-56 UNC thread and 3/32-inch overall length make it suited for small-diameter shaft and collar applications where space is limited. It conforms to ASME/ANSI B18.3 and ASTM F912 standards. Machinists, maintenance technicians, and precision assembly professionals typically install this fastener in production and field-service environments.

This set screw is used in small mechanical and electromechanical assemblies where a headless fastener is required to lock a component onto a shaft or within a threaded bore. Typical applications include motor shaft collars, gear hubs, knobs, and adjustment mechanisms in industrial equipment and instrumentation. Its compact 2-56 thread size makes it common in precision devices and light-duty mechanical linkages. This item is sold in a minimum order quantity of 100 pieces per order.

Key Features

• Cup point geometry bites into mating surfaces for strong rotational and axial hold
• Grade 8 alloy steel construction provides high tensile and torsional strength
• Hex drive accepts a 0.035-inch hex key for installation in confined spaces
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits flush or below the surface for clearance-critical assemblies
• 2-56 UNC thread for use in standard inch-series tapped holes

Compatibility

Designed as a standard inch-series set screw for use in any 2-56 UNC tapped hole requiring a cup point, headless hex-drive fastener per ASME/ANSI B18.3.

Installation Notes

Install with a 0.035-inch hex key torqued by hand to the assembly specification for 2-56 fasteners. Ensure the mating bore is clean and free of debris before threading to avoid galling the alloy steel. De-energize and lock out any equipment before servicing assemblies that contain set screws. Do not substitute a non-conforming drive tool, as rounding the hex socket on small-diameter set screws is common when incorrect key sizes are used.
