The Starrett C11H-12-16R is a professional-grade 12" combination square from Starrett's renowned 11H Series, built for machinists, toolmakers, mechanics, and carpenters who demand precision. Featuring a cast iron square head with black wrinkle finish and a satin chrome, hardened steel blade, this 2-piece set delivers lasting accuracy across woodworking, metalworking, and layout applications.

Graduations are photo-engraved directly into the blade for permanent, wear-resistant readability.
