The classic Starrett metric combination square with precision ground cast iron square head complete with reversible lock bolt, scriber, spirit level, and durable crinkle finish. Both sides of the 300mm hardened steel blade are photo engraved with full mm on one edge and half mm on the other. The heavily plated satin chrome finish (they even grind the rule slightly thinner to allow for the thickness of the plating) now comes as standard throughout the range.
Although there is no current standard for combination squares, Starrett continue to manufacture to a now obsolete U.S. federal specification of 0.004in per foot max deviation for square, with blade edges straight to 0.001in.
All standard Starrett combination set components are interchangeable, so if you later choose to add a centre head, longer rule or protractor, you can be confident that they will work with your existing Starrett kit.
