Value Collection MSC67703124X Taper Pin Size 9 Stainless

Product Description

The VALUE COLLECTION MSC67703124X is a Size 9 taper pin manufactured from 303 grade 18-8 stainless steel with a passivated finish. It measures 3 inches in overall length, with a small end diameter of 0.5286 inches and a large end diameter of 0.591 inches. Taper pins are precision fasteners used to secure hubs, collars, and similar components to shafts, providing reliable alignment and load transfer. The passivated stainless steel construction resists corrosion in wet or chemically exposed environments. This pin conforms to ANSI/ASME B18.8.2 dimensional standards, making it a direct-fit option for applications requiring a compliant, interchangeable taper pin fastener.

Taper pins of this size are commonly used in light industrial, mechanical assembly, and maintenance applications where a removable, precision-alignment fastener is required. Typical installations include shaft-to-hub connections on pumps, compressors, conveyors, and HVAC fan assemblies. The stainless steel material and passivated finish make this pin suitable for use in moist, corrosive, or food-adjacent environments where carbon steel alternatives would be inappropriate. Machinists, millwrights, and maintenance technicians are the primary installers of this type of fastener.

Installation Notes

Taper pins are typically installed by machinists or maintenance technicians using a pin punch and hammer or a taper pin reamer to prepare the mating hole. The tapered hole must be properly reamed to the correct size and taper angle before installation to ensure full contact and correct seating. Always de-energize and lock out equipment before removing or installing taper pins on rotating assemblies. Pins should be driven from the small end and removed by driving from the large end using an appropriate pin punch.
