Value Collection MSC67701045X Taper Pin Size 1 3in Oal Ss

Product Description

The VALUE COLLECTION MSC67701045X is a Size 1 passivated stainless steel taper pin manufactured to ANSI/ASME B18.8.2 standards. It features a small end diameter of 0.1096 inches and a large end diameter of 0.172 inches, with an overall length of 3 inches. The pin is machined from 18-8 Grade 303 stainless steel and finished with a passivated surface treatment to improve corrosion resistance. Taper pins are precision fasteners used to secure hubs, collars, and other components to shafts by way of a self-locking wedging action. This part is installed by machinists, millwrights, and mechanical tradespeople in assembly and maintenance applications.

This taper pin is suited for light-duty to medium-duty mechanical assemblies where a removable, self-locking pin connection is required. Typical applications include securing pulleys, gears, and collars to shafts in industrial machinery, HVAC equipment drives, pump assemblies, and general mechanical systems. The stainless steel construction and passivated finish make it appropriate for environments with elevated moisture or mild corrosive exposure. The minimum order quantity is 5 pieces.

Key Features

• ANSI/ASME B18.8.2 standard compliance ensures dimensional accuracy and interchangeability
• 18-8 Grade 303 stainless steel construction for corrosion resistance in wet or humid environments
• Passivated surface finish enhances oxidation resistance without dimensional change
• Self-locking taper profile eliminates the need for additional fasteners in many applications
• Diameter tolerance range of -0.0007 inches to +0.0013 inches for controlled fit
• Size 1 designation with 3-inch overall length covers a broad range of shaft and hub thicknesses

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 1 taper pin replacement suitable for mechanical assemblies that specify a Size 1 taper pin in stainless steel with a 3-inch overall length.

Installation Notes

Taper pins are typically installed by machinists or millwrights using a pin punch and hammer or a taper pin reamer to prepare the mating hole. Always de-energize and lock out equipment before servicing any rotating assembly. The mating hole should be reamed to the correct taper angle before driving the pin to avoid distortion or loosening in service. Do not force an oversized pin into an undersized hole, as this can damage the hub or shaft.
