Overview

The Starrett 166C is a clamp from Starrett, a brand more often associated with precision measuring instruments. It carries a strong 4.7 rating across 852 reviews, though no dimensions, weight or material were listed for it.

This listing arrived without a seller description or any spec attributes, so the write up leans on brand, category and the rating history rather than size or capacity figures. Buyers who need a confirmed jaw opening or clamping force should look for that detail elsewhere before ordering.

Who it's for
