Value Collection MSC67702480X Taper Pin Size 6 4in Stainless

Product Description

The VALUE COLLECTION MSC67702480X is a Size 6 taper pin machined from 18-8 Grade 303 stainless steel with a passivated finish for corrosion resistance. It measures 4 inches overall length with a small end diameter of 0.2578 inches and a large end diameter of 0.341 inches. Taper pins are precision fastening components used to secure hubs, collars, and similar parts onto shafts or through aligned holes, locking components in a fixed rotational position. Machinists, millwrights, and maintenance technicians install these in mechanical assemblies across industrial, HVAC, and general trade applications.

This taper pin suits residential and commercial mechanical assemblies where a reliable, removable shaft-to-hub connection is required. The passivated stainless steel construction makes it well suited for environments with moisture exposure or where corrosion resistance is a priority. It conforms to ANSI/ASME B18.8.2 dimensional standards, ensuring compatibility with standard taper-reamed holes sized for a Size 6 pin.

Key Features

• Grade 303 18-8 stainless steel construction for corrosion resistance
• Passivated finish adds an additional layer of oxidation protection
• Conforms to ANSI/ASME B18.8.2 dimensional standard
• Small end diameter of 0.2578 inches with tight diameter tolerances (-0.0007 inches minimum, +0.0013 inches maximum)
• 4 inches overall length suits a range of hub and shaft thicknesses
• Sold individually, allowing single-pin replacement or small-quantity procurement

Compatibility

Designed for use in standard taper-reamed holes conforming to ANSI/ASME B18.8.2 specifications for Size 6 taper pins. Verify hole taper and diameter at both ends before installation.

Installation Notes

Taper pins are typically installed by machinists or millwrights using a hammer and pin punch or an arbor press after the mating hole has been properly reamed to the correct taper. Always de-energize and lock out rotating machinery before installing or removing taper pins. Confirm hole alignment and ream to the correct taper angle before driving the pin to avoid galling the stainless steel surface. Do not force an oversized pin into an under-reamed hole.
