This 258 series features a satin chrome scale mounted beside the gage block column for quick reference to nearest 1".
The digital readout reads in .001" while the micrometer head reads to .0001".
Both over and under heights can be checked from the gage blocks in a single setting. Readings can be taken from either left, center or right of the gage block column.
The gage itself is mounted in a heavily flanged frame for stability while the base has three-point hardened bearing pads making the unit virtually tip-proof.
