Value Collection MSC67703249X Taper Pin Size 9 5 in Ss

Product Description

The VALUE COLLECTION MSC67703249X is a Size 9 taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. It measures 5 inches in overall length, with a small end diameter of 0.487 inches and a large end diameter of 0.591 inches. The passivated surface treatment improves corrosion resistance by removing free iron from the outer layer. This pin is manufactured to ANSI/ASME B18.8.2 standards, making it a reliable fastener for mechanical assemblies where precise alignment and secure positioning are required. Machinists, millwrights, and maintenance technicians are the typical installers.

Taper pins of this size are used in a wide range of industrial and mechanical applications including shaft-to-hub connections, gear and pulley alignment, and general machine assembly work. The stainless steel construction makes this pin well suited for environments with moisture exposure or where mild corrosion resistance is needed, such as food processing equipment, marine hardware, and general industrial machinery. The Size 9 designation and 5-inch length target medium-duty assemblies requiring a secure, removable locating pin.

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 9 taper pin for use in any mechanical assembly, fixture, or machine component that accepts a Size 9 taper pin bore.

Installation Notes

Taper pins are typically installed and removed by machinists or millwrights using a pin punch and hammer or a taper pin reamer for final sizing of the bore. Always de-energize and lock out any equipment before servicing components that contain taper pins. Ensure the mating bore is reamed to the correct taper before driving the pin to avoid galling the stainless steel surface. Do not force an oversized pin into an undersized bore, as this can split the hub or damage the assembly.
