Value Collection MSC67703009X Size 8 Stainless Taper Pin

Product Description

The VALUE COLLECTION MSC67703009X is a Size 8 taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. The pin measures 4 inches in overall length, with a small end diameter of 0.4088 inches and a large end diameter of 0.492 inches. The passivated finish improves corrosion resistance by removing free iron from the surface layer. Minimum diameter tolerance is -0.0007 inches and maximum diameter tolerance is +0.0013 inches, providing close-fit precision for mechanical assemblies. Machinists, millwrights, and maintenance technicians install this pin to secure components on shafts or in bores where reliable, removable alignment is required.

This taper pin is suited for use in mechanical assemblies across industrial, HVAC equipment, pump, and general manufacturing applications. The self-locking taper geometry seats firmly under load without additional fasteners. It is appropriate for environments where mild corrosion resistance is needed and where standard ANSI/ASME B18.8.2 dimensional compliance is specified. Sold individually, it is a direct-fit replacement or new-installation option for Size 8 taper pin positions in compatible bored holes.

Key Features

• 303 grade 18-8 stainless steel construction for corrosion resistance in wet or humid environments
• Passivated finish removes surface contaminants and enhances oxidation resistance
• Self-locking taper geometry seats without secondary fasteners
• Tight diameter tolerances (-0.0007 inches / +0.0013 inches) for precise fits
• Conforms to ANSI/ASME B18.8.2 dimensional standards
• 4 inches overall length with Size 8 taper profile

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 8 taper pin for use in any mechanical assembly requiring a Size 8 taper-reamed bore. No specific OEM model compatibility was provided in the product data.

Installation Notes

Taper pins are installed by machinists or maintenance technicians using a taper reamer to prepare the mating bore to the correct size and taper angle before driving the pin. De-energize and lock out any machinery before pin installation or removal. Use a pin punch and hammer to drive the pin fully seated; do not use impact tools that may damage the pin head or bore. Follow all applicable ANSI machinery safety standards during assembly.
