Value Collection 601097PR Set Screw 4-48 X 0.5 in Cup Point

Product Description

The VALUE COLLECTION 601097PR is a cup point set screw designed for secure, non-permanent fastening in mechanical assemblies. This screw features a 4-48 UNF thread size, a 0.5-inch overall length, and a hex drive socket requiring a 0.050-inch hex key. Made from alloy steel, it delivers the hardness and shear strength needed for holding collars, pulleys, knobs, and similar components against a shaft or flat surface. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, this fastener meets established dimensional and mechanical requirements for socket set screws. It is a standard fractional-inch measurement product suited to precision machine assembly and maintenance work.

This set screw is used in light-duty mechanical assemblies where a cup point is required to bite into a shaft surface and resist rotational or axial movement without a protruding head. Typical applications include securing small gears, shaft collars, and knobs in motors, pumps, and instrumentation. The fine 4-48 UNF thread pitch provides increased holding power in thin-walled or small-diameter components. Machinists, maintenance technicians, and mechanical assembly professionals working on precision equipment will encounter this fastener in both OEM manufacturing and field repair contexts.

Key Features

• Cup point geometry bites into shaft material for firm axial and rotational hold
• 4-48 UNF fine thread for increased thread engagement in small components
• 0.5-inch overall length suitable for shallow blind-hole applications
• Alloy steel construction provides hardness and shear resistance
• Hex socket drive requires a 0.050-inch hex key for installation and removal
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards

Compatibility

Designed as a standard ASME/ANSI B18.3 socket set screw suitable for any mechanical assembly requiring a 4-48 UNF cup point fastener with a 0.5-inch overall length. Minimum order quantity is 100 pieces.

Installation Notes

Installation is performed using a 0.050-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the socket. Verify the mating tapped hole meets 4-48 UNF thread specifications before installation. Always de-energize and lock out any machinery before servicing fasteners on rotating components. Do not substitute a mismatched hex key, as this can damage the socket and make removal difficult.
