Value Collection MSC67703041X Taper Pin Size 8 5 in Stainless

Product Description

The VALUE COLLECTION MSC67703041X is a Size 8 taper pin machined from Grade 303 18-8 stainless steel with a passivated finish. It measures 5 inches overall length, with a small end diameter of 0.388 inches and a large end diameter of 0.492 inches. The passivated surface treatment improves corrosion resistance by removing free iron from the steel surface without altering dimensional tolerances. Taper pins are used to secure hubs, collars, and other components to shafts in a reliable, self-locking manner. This pin conforms to ANSI/ASME B18.8.2 dimensional standards and is sold as a single piece.

Taper pins are a standard fastening solution in mechanical assemblies across manufacturing, maintenance, and industrial trades. This Size 8 pin is suited for shaft-to-hub connections, gear and pulley retention, and precision alignment applications where a removable yet positive lock is required. The stainless steel construction makes it appropriate for use in moist or corrosive environments where carbon steel pins would be susceptible to rust.

Key Features

• Grade 303 18-8 stainless steel construction for corrosion resistance
• Passivated finish improves surface resistance without affecting tolerances
• Conforms to ANSI/ASME B18.8.2 dimensional standards
• Self-locking taper geometry for secure shaft and hub retention
• Diameter tolerance range of -0.0007 to +0.0013 inches for precision fit

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 8 taper pin for use in mechanical assemblies requiring a self-locking shaft-to-hub fastener with a 5-inch overall length and matching taper-reamed holes.

Installation Notes

Taper pins are installed by machinists and maintenance mechanics using a taper reamer to prepare the mating hole to the correct taper angle before driving the pin. Power down and de-energize any rotating equipment fully before servicing shaft assemblies. Drive the pin with a pin punch and hammer; do not force an oversized pin into an undersized hole. Removal is accomplished by driving the pin from the small end using a punch.
