Value Collection 101449P Set Screw 3/8-16 X 3/8 in Cup Point

Product Description

The VALUE COLLECTION 101449P is a cup point set screw designed for secure shaft-to-hub and collar locking applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to loosening under vibration and torque loads. The 3/8-16 UNC thread and 3/8-inch overall length make it a standard choice for medium-duty industrial and mechanical applications. Drive engagement is achieved with a 3/16-inch hex key. Compliance with ASME/ANSI B18.3 and ASTM F912 ensures dimensional consistency across the lot. Machinists, millwrights, and maintenance technicians are the typical installers.

This set screw is used wherever a shaft, collar, pulley, gear, or sprocket must be locked to a shaft without a protruding head. Common applications include motor shafts, conveyor components, set collar assemblies, and general mechanical power transmission equipment in both light industrial and commercial settings. The cup point tip bites into the shaft surface to resist axial and rotational movement, making it a reliable choice for permanent or semi-permanent locking arrangements.

Key Features

• Cup point tip bites into shaft material to resist axial and rotational slippage
• Grade 8 alloy steel construction provides high tensile and proof load strength
• 3/8-16 UNC thread for broad compatibility with standard tapped holes
• 3/16-inch hex drive for use with standard Allen or hex key tools
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design eliminates protrusion hazards in rotating assemblies

Compatibility

Designed as a standard ASME/ANSI B18.3 cup point set screw for use in any application with a 3/8-16 UNC tapped hole requiring a headless locking fastener.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 3/16-inch hex key or Allen wrench. Ensure the mating tapped hole is clean and free of debris before threading the screw. Disengage all power sources and lock out equipment before servicing any rotating shaft assembly. Do not exceed the rated capacity of the tapped hole material when applying torque.
