The dial face reads 0.001 inch graduations with 0.001 inch accuracy, confirmed by the included BGIPL STD calibration certificate visible in the photos; the white dial is marked model 13-190-4 and carries the SPI brand logo. The 3.2-inch hardened steel base bridge provides a stable reference surface for measuring bores, slots, steps, and blind holes on milled, turned, or ground workpieces. Six extension rods of varying lengths screw onto the gage's spindle to extend reach, and the unit ships in a fitted foam-lined storage box (part number K15B\/1B per the box label, SKU 75887422) with calibration documentation and a protective poly bag.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid
