Value Collection 101095PR Set Screw 4-48 X 3/8 in Cup Point

Product Description

The VALUE COLLECTION 101095PR is a cup point set screw used to secure components such as collars, gears, and pulleys onto shafts. It features a 4-48 UNF thread specification and measures 3/8 inches in overall length. Manufactured from alloy steel, this screw delivers the hardness and shear strength needed for demanding mechanical assemblies. Drive engagement is via a 0.050-inch hex key socket. It meets ASME/ANSI B18.3 and ASTM F912 standards. Machinists, maintenance technicians, and mechanical assembly professionals install these fasteners across light-duty precision equipment and instrument-grade applications.

This set screw is suited for small-bore shaft retention applications where a headless profile is required to sit flush or below the surface of the mating component. The fine 4-48 UNF thread provides tight engagement in thin-walled or close-tolerance assemblies. Typical applications include small motors, optical instrument mounts, precision machinery, and similar light mechanical assemblies requiring a compact, torque-transmitting fastener. This item is sold in a minimum order quantity of 100 pieces per order.

Key Features

• Cup point tip bites into the shaft surface to resist axial and rotational movement
• 4-48 UNF thread for fine-pitch engagement in close-tolerance bores
• Alloy steel construction provides hardness and shear resistance
• 0.050-inch hex key drive for installation in confined spaces
• Headless design sits flush or below surface of mating part
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as a standard 4-48 UNF cup point set screw for use in any application requiring ASME/ANSI B18.3 compliant headless hex socket fasteners of this thread size and length.

Installation Notes

Installation requires a 0.050-inch hex key. Ensure the mating shaft and threaded bore are clean and free of debris before driving the screw. Apply appropriate thread-locking compound if vibration resistance is required. Do not exceed the torque rating of the alloy steel material or the threaded bore.
