 These Machinist Square sets have four steel square sizes, which can be used for checking carpenter's squares or for using as a try square when marking joints. These general-purpose steel squares are made from high-quality steel for durability and reliability paired with the hardened blade of each square maintaining accurate and precise measurements. 

 This set of machinist squares are manufactured with a perfect right angle on both inside and outside, enabling the verification and set up of machinery or testing edges and faces. Both the blade and stock have received precise grinding to ensure a straight line.
