The set includes two micrometer heads (covering separate sub-ranges within the 0.500–0.800 in span), one extension rod for increased reach, a calibration setting ring gauge (marked 0.56004\" visible in photo), two spanner wrenches for head adjustment, a screwdriver, and a fitted hardwood storage case with foam cutouts. Three-point (trilock\/Bowers-style) inside micrometers contact the bore at 120° intervals for self-centering and highly repeatable bore measurement without a reference surface, making this set well suited for precision bore gauging on engine cylinders, hydraulic bores, and machined housings. SPI (Swiss Precision Instruments) manufactures this set in India to published inch-system standards with a 0.0001 in graduation, ratchet-stop thimble for consistent measuring force, and a satin-chrome finish on all measuring heads.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct
