Value Collection MSC67701441X Taper Pin Size 3 Stainless

Product Description

The VALUE COLLECTION MSC67701441X is a Size 3 taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. It measures 1.25 inches overall length with a small end diameter of 0.193 inches and a large end diameter of 0.219 inches. Diameter tolerances conform to ANSI/ASME B18.8.2, with a minimum tolerance of -0.0007 inches and a maximum of 0.0013 inches. Taper pins of this type are used to secure hubs, collars, and mechanical assemblies to shafts, providing precise and repeatable alignment across industrial and mechanical applications. Installation and removal is handled by machinists and maintenance technicians working with standard hand or press tooling.

This pin is suited for light-to-medium duty shaft-to-hub connections in machinery, conveyor systems, pump assemblies, and general fabrication work where corrosion resistance is a priority. The 303 stainless steel construction makes it appropriate for wet, washdown, or mildly corrosive environments where carbon steel fasteners would degrade. Sold individually per package, with a minimum order quantity of 5 units.

Key Features

• Size 3 taper pin with 0.193-inch small end and 0.219-inch large end diameters
• 303 grade 18-8 stainless steel construction for corrosion resistance in wet or industrial environments
• Passivated finish enhances surface corrosion protection beyond base alloy resistance
• Meets ANSI/ASME B18.8.2 dimensional and tolerance standards
• 1.25 inches overall length suitable for light-to-medium duty shaft and hub connections
• Tight diameter tolerances support precise, repeatable mechanical alignment

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 3 taper pin for use in shaft-to-hub and mechanical assembly applications requiring a passivated stainless steel fastener.

Installation Notes

Taper pins are typically installed and removed by machinists or maintenance technicians using a pin punch, hammer, or arbor press. Always disengage and lock out power to rotating machinery before servicing shaft-mounted components. Ensure the tapered hole is clean and free of burrs before driving the pin to seat. Do not force an oversized pin into an undersized bore, as this can crack the hub or distort the shaft.
