Value Collection MSC67700880X Taper Pin Size 1 Stainless Steel

Product Description

The VALUE COLLECTION MSC67700880X is a Size 1 taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. It measures 1 inch overall length, with a small end diameter of 0.1512 inches and a large end diameter of 0.172 inches. The passivated surface treatment improves corrosion resistance without altering dimensions. Taper pins are precision fasteners used to secure components on shafts, align mating parts, or lock assemblies against rotation and axial movement. This pin is manufactured to ANSI/ASME B18.8.2 standards, making it a reliable choice for maintenance, repair, and original equipment assembly work in mechanical and industrial applications.

Size 1 taper pins in stainless steel are commonly used in light mechanical assemblies where corrosion resistance is required alongside precise fit. Typical applications include shaft-to-hub connections, fixture alignment, and machine component locking in environments exposed to moisture, mild chemicals, or cleaning agents. Machinists, maintenance technicians, and mechanical assemblers use these pins in food processing equipment, marine hardware, pump assemblies, and general industrial machinery where carbon steel fasteners are not suitable.

Key Features

• Size 1 taper pin conforming to ANSI/ASME B18.8.2 standard dimensions
• 303 grade 18-8 stainless steel construction for corrosion resistance in wet or chemical environments
• Passivated finish removes surface iron and enhances oxidation resistance without dimensional change
• Small end diameter of 0.1512 inches, large end diameter of 0.172 inches for precise taper fitment
• 1 inch overall length suitable for light to medium mechanical assemblies
• Diameter tolerance range of -0.0007 inches to +0.0013 inches for controlled fit

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 1 taper pin replacement or original installation component for mechanical assemblies requiring a stainless steel passivated taper pin with a 1 inch overall length.

Installation Notes

Taper pins are typically installed by machinists or mechanical technicians using a tapered reamer to prepare the hole to the correct taper before driving the pin into place with a pin punch and hammer. Confirm hole taper matches ANSI/ASME B18.8.2 Size 1 specifications before installation. De-energize and lock out all equipment before servicing any shaft or rotating assembly. Never drive a taper pin into an improperly reamed hole, as this can cause material deformation or fastener failure.
