End Measuring Rods and St andards 234 End Measuring Rods with Spherical Ends 1-24"/25-600MM These rods or "standards" are for checking and setting micrometers of 2" capacity and larger, and are also used on machine tools for comparing gages, checking precision measuring tools, for measuring parallel surfaces, and many other types of work. They are made of special tool steel in rod form with ends hardened and accurately lapped to a spherical radius. Available plain or with insulated handles to minimize expansion by heat when held in the hand. 1-6" (25-150mm) sizes are 1/4" (6.3mm) diameter; 7-11" (175-275mm) sizes, 3/8" (9.5mm) diameter; 12-24" (300-600mm) sizes are 7/16" (11mm) diameter. NOTE: These standards are the ones used for all micrometers furnished with standards. Larger sizes available on special order. 234 End Measuring Rods With Insulating Handle Length Cat.
