This round end rigid blade rule is manufactured from the finest quality spring-tempered stainless steel with a satin chrome, anti-glare finish for exceptional readability and durability. The rust-resistant surface features permanent black figures and graduations that remain clear over time. Metric blades are subdivided to 0.5 mm and 1 mm and clearly figured every 10 mm, while inch blades are subdivided to 1/16, 1/32, and 1/64 and figured every inch for precise measurement in both systems. The 150 mm length is supplied with a 19 mm blade width, with additional lengths available at 25 mm blade width, all including a convenient hanging hole for easy storage. Accuracy is ±0.2 mm full scale with a constant at 20°C, making this rigid blade ideal for engineering, metalworking, woodworking, and precision workshop use.
