Value Collection MSC67701920X Taper Pin Size 4 4in Ss

Product Description

The VALUE COLLECTION MSC67701920X is a Size 4 stainless steel taper pin manufactured to ANSI/ASME B18.8.2 standards. It features a small end diameter of 0.1668 inches and a large end diameter of 0.25 inches, with an overall length of 4 inches. Constructed from 303 18-8 stainless steel with a passivated finish, this pin resists corrosion in demanding service environments. Taper pins are used to secure hubs, collars, and similar components to shafts, providing precise alignment and easy removal when required. Machinists, millwrights, and maintenance technicians are the primary installers.

This taper pin is suited for general industrial and mechanical assembly applications where a reliable, removable shaft-to-hub connection is needed. The passivated stainless steel construction makes it appropriate for environments exposed to moisture, mild chemicals, or sanitary process requirements. Typical applications include pump assemblies, conveyor components, and precision machine elements where repeatable positioning is critical.

Key Features

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 4 taper pin for use in any mechanical assembly requiring a tapered pin connection of matching hole size and taper specification.

Installation Notes

Taper pins are installed by a machinist or millwright after drilling and reaming the mating components to the correct tapered hole specification. Always de-energize and lock out the equipment before servicing any shaft-mounted components. Drive the pin with a suitable pin punch and hammer, and use a taper pin reamer to ensure proper hole geometry before installation. Remove the pin by driving from the small end using a punch of appropriate diameter.
