These precision squares are made by Kinex to Accuracy Class 0 according to DIN 875/0. Their accuracy is several times better than many other high accuracy woodworking squares. Unlike some of the other stainless steel Kinex squares we carry, these squares are made of hardened steel, so they do need to be protected from corrosion - they are shipped with a grease coating, inside of a bag, along with a foam lined cardboard box, except for the largest size which comes in cardboard box.
We stock seven sizes of this line of squares:
60 mm x 40 mm, with 16 mm wide x 3 mm thick blade, and 16 mm wide x 9 mm thick base. Accuracy Class 0 to DIN 875 is equivalent to a squareness of better than 0.007 mm (0.00028") along the entire length of the square.
75 mm x 50 mm, with 16 mm wide x 3 mm thick blade, and 16 mm wide x 9 mm thick base. Accuracy Class 0 to DIN 875 is equivalent to a squareness of better than 0.007 mm (0.00028") along the entire length of the square.
100 mm x 70 mm, with 16 mm wide x 3 mm thick blade, and 18 mm wide x 9 mm thick base. Accuracy Class 0 to DIN 875 is equivalent to a squareness of better than 0.007 mm (0.00028") along the entire length of the square.
