Value Collection MSC67552729X Taper Pin Size 9 Steel

Product Description

The VALUE COLLECTION MSC67552729X is a Size 9 uncoated steel taper pin manufactured to ANSI/ASME B18.8.2 standards. The pin measures 2 inches overall length with a small end diameter of 0.5494 inches and a large end diameter of 0.591 inches. Made from Grade C-12L14 steel, it delivers consistent dimensional accuracy with a minimum diameter tolerance of -0.0007 inches and a maximum diameter tolerance of 0.0013 inches. Machinists, maintenance technicians, and assembly professionals use taper pins to secure hubs, collars, and machine components to shafts in a removable, self-locking configuration.

This taper pin is suited for general industrial assembly and machine shop applications where a reliable, repositionable fastening method is needed. The Size 9 designation conforms to the ANSI/ASME B18.8.2 standard sizing system, making it a direct fit wherever that specification is called out on engineering drawings. Typical applications include shaft-to-collar connections, gear assemblies, and fixture alignment in both production and maintenance environments.

Installation Notes

Taper pins are typically installed and removed 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 taper before installation to ensure full contact along the pin length. Always de-energize and lock out machinery before removing or installing taper pins on rotating shafts or assemblies. Do not drive pins into undersized holes, as this can crack hubs or split collars.
