This Starrett spring-tempered stainless steel rule has photo-engraved graduations in inches and millimetres and a satin-chrome finish for measuring in woodworking, carpentry, and machining applications. Its graduations are in 32nds of an inch and half millimetres on one side and 64ths of an inch and millimetres on the opposite side. They are photo engraved for accuracy and staggered in a height pattern for readability. The spring-tempered stainless steel body construction is fully flexible for durability and flexibility. The satin chrome finish aids readability and provides rust resistance. Rules are devices used to measure distances, or to rule straight lines. Rules have markings at specified intervals (also called graduations), as opposed to straight edges, which lack graduations and are used solely to draw a straight line. Nearly all rules are straight edges, except for rounded rules used to measure circles and arcs of angles in geometry applications. Rules can vary from high-quality steel instruments used by machinists; to retractable rules (also called tape measures) used in carpentry and for home-use; to simple wooden or plastic rules used in primary and secondary schools. The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.
