Value Collection MSC67703405X Taper Pin Size 10 4in Stainless

Product Description

The VALUE COLLECTION MSC67703405X is a Size 10 taper pin machined from Grade 303 18-8 stainless steel with a passivated finish for corrosion resistance. It measures 4 inches overall length with a small end diameter of 0.6228 inches and a large end diameter of 0.706 inches. The passivation treatment removes surface iron and enhances the natural oxide layer, improving resistance to rust and chemical exposure. This pin meets ANSI/ASME B18.8.2 dimensional standards. Taper pins are used by machinists, millwrights, and mechanical assemblers to lock hubs, collars, and mechanical components onto shafts with a reliable, self-locking fit.

This taper pin is suited for industrial and mechanical assembly applications where a precise, removable connection between a shaft and mating component is required. The stainless steel construction makes it appropriate for environments with moisture, mild chemicals, or sanitary requirements. Typical installations include pump assemblies, drive shafts, gear hubs, and rotating equipment found in HVAC, plumbing, and light industrial mechanical systems. This pin is sold individually.

Installation Notes

Taper pins are typically installed and removed by machinists or millwrights using a taper pin reamer, hammer, and punch. Always de-energize and lock out the equipment before servicing any rotating assembly. Drive the pin from the small end toward the large end for seating; use a punch on the large end to drive it out for removal. Verify that the reamed hole in the mating component matches the taper and size specifications before installation.
