A heavy‑base 90‑degree flat edge square designed for accurate checking of straightness, parallelism, and perpendicularity in machining and inspection work. The hardened stainless‑steel body provides long service life, while the satin‑chrome finish gives clear, glare‑free readability. The wide, precision‑ground base offers excellent stability on surface plates and machine tables, and all measuring surfaces are ground and lapped for consistent, repeatable accuracy. Built to DIN 875/0, it delivers workshop‑grade precision across a compact size range.
