Value Collection 601055PR Set Screw 3-48 X 5/16 in Cup Point

Product Description

The VALUE COLLECTION 601055PR is a cup point set screw designed for mechanical assemblies requiring a secure, non-projecting fastener. Sized at 3-48 x 5/16 inches overall length, this screw uses a hex drive and features a cup point tip that bites into a mating shaft to resist rotational and axial movement. Made from alloy steel, it provides the strength and hardness required for demanding clamping applications. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, it meets recognized dimensional and mechanical requirements. This fastener is a standard choice for machinists, millwrights, and maintenance technicians working with precision assemblies.

Cup point set screws of this size are commonly used in light-duty mechanical assemblies such as collars, gears, pulleys, and hubs where a flush or sub-flush fastener is needed. The 3-48 UNC thread is a fine-pitch designation suited for small-diameter components. This fastener is appropriate for both OEM manufacturing environments and field repair applications across industrial, HVAC, and general mechanical trades.

Key Features

• Cup point tip provides positive grip on mating shaft surfaces to resist slippage
• 3-48 UNC thread standard for compatibility with standard tapped holes in small components
• Hex drive accepts a 0.050-inch hex key for installation in confined spaces
• Alloy steel construction delivers hardness and shear strength suitable for clamping loads
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Overall length of 5/16 inches measured as full fastener length

Compatibility

Designed as a standard replacement or stock fastener for mechanical assemblies using 3-48 UNC tapped holes requiring a cup point set screw per ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a 0.050-inch hex key. Ensure the mating tapped hole is clean and free of debris before threading the screw. Disengage power and de-energize all rotating equipment before servicing any assembly containing set screws. Do not exceed the rated torque capacity of the tapped hole material, particularly when working with soft metals or plastics.
