| Precision gauge blocks are the primary standards vital to dimensional quality control in the manufacture of parts |
| Provided with inspection certificate |
| This grade is used within an inspection area to verify the accuracy of plug and snap gauges, as well as for setting electronic measuring devices |
| Perfect wringing is possible using the center hole - after wringing the square gauge blocks, an optional tie rod can be inserted through the center hole to fix the blocks using a screw |
| A height reference standard can easily be made - a precision height reference standard can be made easily and inexpensively using accessories such as the plain jaw and block base |
| A dedicated inspection jig can be easily made - a dedicated inspection jig for periodic inspection of instruments can be made easily and inexpensively |
| A wide measuring surface with cross section dimensions of [24.1 x 24.1 mm/0.95 x 0.95 in] is available |
| A square gauge block can retain stable orientation both longitudinally and laterally |
| A wide range of application measurements can be made, including cutting tool positioning, angle measurement with a sine bar, taper measurement with a roller and inspection of depth micrometers |
