Value Collection MSC67701763X Taper Pin Size 4 Stainless Steel

Product Description

The VALUE COLLECTION MSC67701763X is a Size 4 taper pin machined from 303 stainless steel with a passivated finish. It features a small end diameter of 0.2188 inches and a large end diameter of 0.25 inches, with an overall length of 1.5 inches. Taper pins are precision fasteners used to locate, align, or secure machine components such as hubs, collars, and shafts. The passivated 18-8 stainless steel construction provides corrosion resistance suitable for demanding environments. Machinists, maintenance technicians, and industrial mechanics typically install these in mechanical assemblies where repeatable, self-locking alignment is required.

This taper pin is suited for use in light to medium-duty mechanical assemblies across industrial, commercial, and maintenance applications. It conforms to ANSI/ASME B18.8.2 standards, making it a direct-fit option wherever a Size 4 taper pin is called out on an engineering drawing or maintenance spec sheet. Typical applications include shaft-to-hub connections, gear and pulley alignment, and precision fixture assembly in both original equipment and field repair scenarios.

Installation Notes

Taper pins are typically installed by machinists or maintenance mechanics using a properly sized taper pin reamer and a pin driver or press. The receiving hole must be reamed to the correct taper before installation to ensure a self-locking fit. Always de-energize and lock out the machine before servicing any assembly containing taper pins. Removal typically requires a punch and hammer driven from the small end.
