Value Collection MSC67702845X Taper Pin Size 8 2in Stainless

Product Description

The VALUE COLLECTION MSC67702845X is a Size 8 taper pin manufactured from Grade 303, 18-8 stainless steel with a passivated finish. It measures 2 inches overall length with a small end diameter of 0.4504 inches and a large end diameter of 0.492 inches. Taper pins are cylindrical fasteners with a uniform taper used to secure components such as hubs, collars, and levers to shafts, preventing rotational or axial movement. The passivated stainless steel construction provides corrosion resistance suitable for demanding service environments. This pin is installed by machinists, millwrights, and maintenance technicians in mechanical assemblies across industrial and commercial applications.

This taper pin is suited for use in mechanical assemblies where a removable, self-locking fastener is required to align or secure mating components. Typical applications include shaft-to-hub connections, gear and pulley retention, and precision alignment in industrial machinery. The Size 8 designation and ANSI/ASME B18.8.2 standard compliance make it a direct fit in applications engineered to that specification. Sold individually, it is appropriate for repair, replacement, or new assembly work.

Key Features

• Grade 303, 18-8 stainless steel construction for corrosion resistance in wet or chemically exposed environments
• Passivated finish removes surface contaminants and enhances natural oxide layer for added corrosion protection
• Conforms to ANSI/ASME B18.8.2 standard for consistent taper geometry and dimensional accuracy
• Diameter tolerance of -0.0007 inches minimum and +0.0013 inches maximum for controlled fit
• Self-locking taper design seats securely under load without additional fasteners
• Sold as a single pin, suitable for one-off repairs or low-quantity assembly work

Compatibility

Designed as an ANSI/ASME B18.8.2 standard Size 8 taper pin, compatible with any taper-reamed hole engineered to accept a Size 8 pin per that specification.

Installation Notes

Taper pins are installed by machinists or maintenance technicians using a properly sized taper pin reamer to prepare the hole before driving the pin. Always ensure the mating components are secured and the assembly is de-energized or locked out before insertion or removal. Drive the pin with a pin punch and hammer to seat it fully; use a pin punch from the small end to remove. Do not force an undersized pin into an improperly reamed hole, as this can damage mating components or cause the pin to shear under load.
