Value Collection 101277P Set Screw 10-32 X 3/8 in Cup Point

Product Description

The VALUE COLLECTION 101277P is a 10-32 cup point set screw used to lock a component — such as a collar, gear, or pulley — against a shaft or into a threaded bore without a protruding head. Manufactured from Grade 8 alloy steel, it delivers the tensile strength needed for high-load or vibration-prone fastening applications. The 3/32-inch hex drive accepts a standard hex key for installation and removal in tight spaces. This screw conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it suitable for industrial and mechanical assembly work performed by machinists, millwrights, and maintenance technicians.

This set screw is suited for use in rotating machinery, shaft collars, set-screw couplings, and similar mechanical assemblies found in industrial plants, commercial HVAC equipment, pump systems, and conveyor equipment. The cup point bites into the mating surface to resist axial and rotational movement, making it a common choice when a more aggressive grip is needed compared to a flat or oval point. The overall length of 3/8 inches fits standard thread depths in moderate-duty assemblies.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cup point geometry bites into mating surface for secure shaft retention
• 10-32 thread size conforms to UNC/UNF standards for broad compatibility
• 3/32-inch hex drive for use with standard hex keys in confined spaces
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design allows flush or below-surface installation

Compatibility

Designed as a standard 10-32 cup point set screw for use in any threaded bore or assembly that requires ASME/ANSI B18.3 and ASTM F912 compliant fasteners in a 3/8-inch overall length.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 3/32-inch hex key. Ensure the mating bore and shaft surfaces are clean and free of debris before driving the screw. Do not exceed the rated drive torque for the hex socket size, as over-torquing can strip the socket or shear the screw. De-energize and lock out any equipment before servicing assemblies that contain set screws.
