Value Collection 101405P Set Screw 5/16-24 X 1/4 in Cup Point

Product Description

The VALUE COLLECTION 101405P is a cup point set screw designed for secure, no-protrusion fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength for demanding industrial and commercial applications. It features a 5/16-24 unified fine thread and measures 1/4 inch in overall length. Drive engagement is through a 5/32-inch hex key socket. The cup point tip bites into mating surfaces to resist rotation and axial movement without requiring a through-hole. Machinists, millwrights, and maintenance technicians commonly install these screws to lock collars, pulleys, gears, and shafts in position.

This set screw is suited for use in rotating shaft assemblies, machine tool fixtures, conveyor components, and other mechanical drive systems where a flush or recessed fastener is required. The fine thread pitch provides precise positioning and strong clamping force in metal-to-metal applications. Conformance to ASME/ANSI B18.3 and ASTM F912 standards makes it appropriate for use in regulated industrial environments where fastener grade and geometry must meet documented specifications.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cup point geometry bites into shaft or mating surface to resist slippage
• 5/16-24 unified fine thread for precise torque and positioning control
• 5/32-inch hex key drive for standard Allen wrench installation
• Headless design sits flush or below surface for clearance-critical assemblies
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 5/16-24 cup point set screw in alloy steel.

Installation Notes

Installation requires a 5/32-inch hex key. Ensure the mating shaft or component surface is clean and free of burrs before seating the cup point. Apply thread-locking compound if vibration resistance is required by the application. Always follow applicable machinery safety lockout/tagout procedures before servicing assemblies containing set screws.
