Value Collection MSC67552968X Size 9 Steel Taper Pin

Product Description

The VALUE COLLECTION MSC67552968X is a Size 9 taper pin machined from C-12L14 steel with no surface coating. It measures 4 inches overall length with a small end diameter of 0.5078 inches and a large end diameter of 0.591 inches. Taper pins are precision fasteners used to locate, align, or secure components on shafts, hubs, and assemblies. The C-12L14 grade provides good machinability and consistent dimensional tolerances, making this pin suitable for applications where repeatable fit and precise alignment are required. Machinists, maintenance technicians, and millwrights typically install these pins in light to medium-duty mechanical assemblies.

This taper pin is intended for use in mechanical assemblies where a removable, self-locking locating fastener is needed. Typical applications include securing collars to shafts, aligning mating bores, and fixing gears or couplings to rotating components. The uncoated finish makes it appropriate for indoor or controlled-environment use where corrosion is not a primary concern. It conforms to ANSI/ASME B18.8.2, the standard governing taper pins in the United States, ensuring dimensional interchangeability with other compliant tooling and components.

Key Features

Compatibility

Designed as a standard ANSI/ASME B18.8.2-compliant Size 9 taper pin for use in mechanical assemblies requiring a self-locking locating fastener in a matching tapered bore.

Installation Notes

Taper pins are installed by a machinist or maintenance technician using a pin punch and hammer or an arbor press to drive the pin into a pre-reamed tapered bore. Always de-energize and lock out the machine before installing or removing taper pins in rotating equipment. The mating bore should be reamed to the correct taper to achieve full contact along the pin length. Do not force an oversized pin into an undersize bore, as this can crack the hub or distort the shaft.
