84MAZ-161-5J Dial Bore Gages (76.2 - 131.75mm Range)

84, 84M Dial Bore Gages with Cases
Dial Bore Gage, 76.2-131.75mm Range, 0.002mm Graduations, Wooden Case

Starrett 84 bore gages allow for bore measurements beyond the size range of our 82 Series. They are comparison gages and should be set with a master ring gage, gage blocks with parallel jaws, outside micrometers or vernier calipers. Ring gages are available by request, quoted by application. Good practice is to set the gage to zero, as near to the desired dimension as possible. 76.2-131.75mm Range 0.002mm Grad
