Cast iron 90 ° square ruler

The Cast iron 90 ° square ruler is an indispensable measuring tool in the machinery industry.It is mainly used for inspection and line marking to ensure the precision of right angles in parts or components.When installing,adjusting,and repairing equipment,it can also be used to inspect the perpendicularity of parts or components,ensuring the flatness of working surfaces.

The cast iron square ruler features high precision,stable performance,low cost,and easy maintenance.It also has excellent durability,is not prone to deformation,and is convenient to carry and store.When not in use for a long time,simply applying a thin layer of industrial oil on its surface can effectively prevent rust and keep the square ruler in optimal condition.

When using a cast iron square ruler,it is crucial to pay attention to its placement and ensure it is not tilted.The square ruler should be vertically abutted against the workpiece being measured,perpendicular to the intersection line of the two surfaces forming the right angle,so as to avoid measurement errors.Before use,the working surface of the square ruler and the surface to be inspected must be cleaned and kept flat.This ensures the accuracy of the measurement and prevents damage to the square ruler.
