Value Collection 101487PR Set Screw 3/8-24 X 1 in Cup Point

Product Description

The VALUE COLLECTION 101487PR is a 3/8-24 UNF cup point set screw machined from Grade 8 alloy steel. Set screws are headless fasteners used to secure a component — such as a collar, pulley, or gear — against a shaft by bearing directly into the mating surface. The cup point concentrates clamping force into a small contact area, providing strong resistance to rotation and axial movement. Drive engagement is via a 3/16-inch hex key socket. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, making it suitable for precision mechanical assemblies where dimensional consistency and material strength are required.

This set screw is used in mechanical, industrial, and light manufacturing applications wherever a flush or recessed fastener is needed to lock rotating or sliding components onto a shaft. Common install scenarios include motor shaft collars, conveyor components, valve stems, and machine tool fixtures. The 3/8-24 UNF thread provides fine thread engagement for controlled torque and vibration resistance. Minimum order quantity is 100 pieces; package quantity is 1.

Key Features

• Cup point geometry concentrates holding force for strong shaft grip
• Grade 8 alloy steel construction for high tensile and torsional strength
• 3/8-24 UNF fine thread for precise torque control and vibration resistance
• 3/16-inch hex socket drive for standard hex key installation
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design allows fully recessed installation flush with or below the work surface

Compatibility

Designed as an OEM-style replacement or standard fastener for mechanical assemblies requiring a 3/8-24 UNF cup point set screw in Grade 8 alloy steel.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen driver. Ensure the mating shaft and bore are clean and free of burrs before seating the screw. Apply appropriate thread-locking compound if vibration is a concern in the application. Always torque to the fastener manufacturer or equipment OEM specification for Grade 8 alloy steel set screws.
