Value Collection MSC67700245X Taper Pin Size 4/0 Ss

Product Description

The VALUE COLLECTION MSC67700245X is a Size 4/0 taper pin manufactured from Grade 303, 18-8 passivated stainless steel. It features a small end diameter of 0.0986 inches and a large end diameter of 0.109 inches, with an overall length of 0.5 inches. The passivated finish provides enhanced corrosion resistance, making this pin well-suited for precision mechanical assemblies where moisture or chemical exposure is a concern. Taper pins are used to secure hubs, collars, and levers to shafts, and are commonly installed by machinists, millwrights, and maintenance technicians working on mechanical drivetrain and positioning components.

This taper pin is appropriate for use in light-duty precision assemblies requiring a standardized, self-locking pin connection. Its small profile and stainless steel construction make it a fit for instrumentation, pumps, valves, and general mechanical assemblies where a reliable, removable pin joint is needed. It conforms to ANSI/ASME B18.8.2, which governs taper pin dimensions and tolerances, ensuring interchangeability with other conforming components in the same size series.

Key Features

• Grade 303, 18-8 stainless steel construction for corrosion resistance in wet or chemical environments
• Passivated finish removes free iron from the surface, improving long-term corrosion resistance
• Size 4/0 with 0.0986 inch small end and 0.109 inch large end diameters for precise fitment
• 0.5 inch overall length suitable for thin-section and compact assemblies
• Conforms to ANSI/ASME B18.8.2 for dimensional interchangeability
• Diameter tolerance range of -0.0007 to +0.0013 inches for controlled fit

Compatibility

Designed as an ANSI/ASME B18.8.2 conforming Size 4/0 taper pin, compatible with any tapered hole reamed to the same standard in mechanical assemblies requiring a self-locking pin connection.

Installation Notes

Taper pins are typically installed by machinists or maintenance technicians using a taper pin reamer to prepare the mating hole to the correct angle before driving the pin. Always ensure the tapered hole is reamed clean and free of burrs before installation. Drive the pin with a pin driver or hammer and punch, seating it firmly so the taper provides the locking force. To remove, drive the pin from the small end using a suitable punch, taking care not to damage the mating components.
