Value Collection MSC67700401X Taper Pin Size 3/0 Stainless

Product Description

The VALUE COLLECTION MSC67700401X is a Size 3/0 taper pin manufactured from Grade 303 18-8 passivated stainless steel. The pin measures 0.5 inches in overall length with a small end diameter of 0.1146 inches and a large end diameter of 0.125 inches. The passivated finish enhances corrosion resistance, making this pin suitable for applications where moisture or chemical exposure is a concern. Taper pins are precision fasteners used to secure hubs, collars, and similar components to shafts, providing a reliable mechanical connection that resists rotation and axial movement. Machinists, millwrights, and maintenance technicians are the primary installers of this type of fastener.

This taper pin is suited for light-duty mechanical assemblies in industrial, commercial, and equipment maintenance applications. The Size 3/0 designation indicates a standardized taper geometry per ANSI/ASME B18.8.2, ensuring dimensional consistency across replacement and new-installation use. Typical applications include securing levers, gears, or couplings to shafts in machinery where precise alignment and a removable pin connection are required. The stainless steel construction makes it appropriate for food-processing equipment, marine hardware, and other corrosion-sensitive environments.

Key Features

• Conforms to ANSI/ASME B18.8.2 standards for dimensional accuracy
• Diameter tolerance range of -0.0007 to +0.0013 inches for consistent fit

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 3/0 taper pin replacement for mechanical assemblies requiring a 0.1146-inch to 0.125-inch taper pin connection.

Installation Notes

Taper pins are typically installed and removed by machinists or maintenance technicians using a pin punch, hammer, or arbor press. Always de-energize and lock out equipment before servicing any mechanical assembly. The tapered bore in mating components must match the pin taper to ensure proper seating and load transfer. Forced installation into an undersized or misaligned bore can damage the bore or fracture the pin.
