Value Collection MSC67701482X Taper Pin Size 3 Stainless

Product Description

The VALUE COLLECTION MSC67701482X is a Size 3 taper pin machined from Grade 303 18-8 stainless steel with a passivated finish. It measures 1.5 inches in overall length with a small end diameter of 0.1878 inches and a large end diameter of 0.219 inches. The passivated surface improves corrosion resistance by removing free iron from the stainless surface without altering the base metal. Taper pins are used to secure hubs, collars, and similar components to shafts, providing a reliable mechanical connection that is easy to drive in and remove during maintenance. This pin is manufactured to ANSI/ASME B18.8.2 dimensional standards.

Taper pins of this size are commonly used in light mechanical assemblies, machine tool fixtures, pump components, and general industrial equipment where a removable, self-locking pin connection is required. The stainless steel construction makes this pin well suited for applications exposed to moisture, mild chemicals, or environments where corrosion resistance is a priority. Machinists, millwrights, and maintenance technicians typically specify and install taper pins of this type during equipment assembly or repair work.

Key Features

• Grade 303 18-8 stainless steel construction for corrosion resistance in wet or chemical-exposure environments
• Passivated finish removes surface iron contamination and enhances long-term corrosion resistance
• Size 3 designation per ANSI/ASME B18.8.2 for consistent dimensional interchangeability
• Small end diameter of 0.1878 inches and large end diameter of 0.219 inches for standard taper fit
• 1.5 inches overall length suitable for light-to-medium duty shaft and hub connections
• Controlled diameter tolerances (-0.0007 inches minimum, +0.0013 inches maximum) for reliable fit

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 3 taper pin replacement for use in any application requiring a 1.5-inch passivated stainless steel taper pin of this diameter range.

Installation Notes

Taper pins are driven into a reamed taper hole using a pin punch and hammer; the hole must be reamed to the correct taper before installation. Ensure the shaft and hub assembly is fully secured and de-energized before driving or removing pins. Use a properly sized pin punch to avoid deforming the small end during removal. Follow applicable machinery safety lockout/tagout procedures before beginning pin service.
