Value Collection 101055PR Set Screw 3-48 X 3/32 in Cup Point

Product Description

The VALUE COLLECTION 101055PR is a cup point set screw designed for mechanical assemblies where a fastener must seat flush within a tapped hole and apply clamping force to a shaft or mating surface. Threaded 3-48 UNC with an overall length of 3/32 inches, this screw is driven by a 0.050-inch hex key and is manufactured from Grade 8 alloy steel to deliver high tensile strength in compact fastening applications. It conforms to ASME/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and mechanical assemblers install this type of fastener in precision components where protrusion above the surface is not acceptable.

This set screw suits residential and commercial mechanical assemblies including shaft collars, pulleys, knobs, and small mechanical linkages where a headless fastener is required. The cup point geometry bites into the mating shaft surface to resist rotational and axial movement. Its small thread size makes it appropriate for light-duty precision equipment, instrumentation hardware, and fine-thread fastening applications where space is limited.

Key Features

• Cup point geometry grips shaft surfaces to resist rotation and axial shift
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 3-48 UNC thread standard for fine-pitch engagement in precision applications
• Hex drive (0.050 inches) for installation with a standard hex key
• Headless design seats fully flush within tapped holes
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 3-48 UNC headless cup point set screw in alloy steel.

Installation Notes

Installation is performed by machinists, assemblers, or maintenance technicians using a 0.050-inch hex key. Ensure the receiving tapped hole is clean and free of debris before driving the screw. Do not exceed the rated drive torque for the thread size, and avoid substituting a larger hex key that could round the socket. Secure the assembly and relieve any load on the shaft prior to installation or removal.
