Value Collection 101043PR Set Screw 2-56 X 1/8 in Cup Point

Product Description

The VALUE COLLECTION 101043PR is a cup point set screw designed for secure, low-profile fastening in mechanical assemblies where a flush or recessed fastener is required. Manufactured from Grade 8 alloy steel, this screw delivers high tensile strength and resistance to shear forces, making it well suited for locking collars, hubs, pulleys, and shafts in position. The hex drive requires a 0.035-inch hex key for installation. At a 2-56 thread size and 1/8-inch overall length, this screw is sized for precision applications in compact mechanical or electromechanical components. It meets ASME/ANSI B18.3 and ASTM F912 standards.

This set screw is used in applications where a fastener must bear against a shaft or mating surface without protruding beyond the outer diameter of the host component. Typical applications include small motor assemblies, instrumentation hardware, HVAC actuator linkages, and light industrial mechanical assemblies. The cup point geometry creates a biting contact that resists rotational and axial movement. This screw is sold individually per package with a minimum order quantity of 100 pieces.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength
• Cup point geometry bites into mating surface to resist shaft movement
• Hex drive with 0.035-inch key size for precise torque application in confined spaces
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• UNC thread standard, 2-56 thread size, 1/8-inch overall length
• Fractional inch measurement type for standard tooling compatibility

Compatibility

Designed as a standard UNC 2-56 set screw suitable for any application requiring an ASME/ANSI B18.3-compliant cup point fastener in that thread size and length.

Installation Notes

Installation should be performed by a qualified mechanic or technician using a calibrated 0.035-inch hex key. Ensure the mating shaft or surface is clean and free of debris before seating the cup point. De-energize and lock out any equipment before servicing fasteners on rotating assemblies. Do not exceed the rated drive torque for the thread size, as over-torquing a 2-56 fastener can strip threads or fracture the screw body.
