JessEm 300 mm Stainless Steel Precision Square

JessEm stainless-steel precision square, 300 mm, metric. It is made of 301 full-hard stainless steel, and the markings are etched and then laser-engraved so they never fade. JessEm's patented Flex Grip tabs grip virtually any surface softer than the steel, so the square won't slip when marking or scribing wood, metal or paper. Scribing notches every 1 mm give accurate lines, and a balancing tab that flips out and locks lets the square balance on the work while scribing. Engraving is accurate within 0.004" and each square is set within 0.002" over the length of the blade.

Also available in 150 and 200 mm.
