Value Collection MSC67702969X Taper Pin Size 8 Stainless Steel

Product Description

The VALUE COLLECTION MSC67702969X is a Size 8 taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. Taper pins are precision fasteners used to secure hubs, collars, and machine components to shafts, providing accurate and repeatable alignment. This pin measures 3.5 inches in overall length with a small end diameter of 0.4192 inches and a large end diameter of 0.492 inches. The passivated stainless steel construction provides corrosion resistance in wet or chemically active environments. It conforms to ANSI/ASME B18.8.2 dimensional standards, making it a direct-fit replacement in applications specifying a Size 8 taper pin to that standard.

This taper pin is suited for use in mechanical assemblies found in HVAC equipment, pumps, motors, and general industrial machinery. It is commonly installed by maintenance technicians and millwrights during shaft-to-hub assembly, equipment overhaul, or precision alignment work. The stainless steel material and passivated surface make it appropriate for environments where moisture exposure or mild corrosive conditions are a concern, including pool equipment, plumbing pump assemblies, and refrigeration mechanical systems.

Compatibility

Designed as an OEM-style replacement taper pin for mechanical assemblies requiring a Size 8 taper pin conforming to ANSI/ASME B18.8.2.

Installation Notes

Taper pins are typically installed and removed by machinists or maintenance technicians using a pin punch and hammer or an arbor press. Always de-energize and lock out equipment before servicing any shaft or hub assembly. The tapered hole in the mating components must be reamed to the correct Size 8 taper to ensure proper fit and load transfer. Do not force an oversized pin into an underreamed hole, as this can crack the hub or distort the shaft.
