A flat‑edge 90‑degree square designed for checking straightness, parallelism, and perpendicularity in machining, fabrication, and general engineering work. The hardened stainless‑steel body provides long service life, and the satin‑chrome finish gives low‑glare readability on the reference faces. All measuring surfaces are precision‑ground and lapped for smooth, repeatable contact on machine tables, surface plates, and workpieces. Manufactured to DIN 875, this basic version delivers reliable workshop‑grade accuracy across a wide size range, with both Grade 0 and Grade 2 options available.
