Mitutoyo rectangular steel gage block sets are the premium steel choice in the WESTport assortment. Mitutoyo's controlled heat treatment is applied repeatedly to reduce dimensional change over time, while advanced lapping provides the flatness and surface finish required for precision wringing.

Choosing a Configuration

The 35-piece sets contain a carefully selected group of commonly useful inch dimensions, for customers who want Mitutoyo precision and traceability without purchasing a full 81-piece set. They keep the set compact and easy to manage. AS-2 is the entry point; Grade 0 is the tighter choice for calibration laboratories and manufacturing quality operations.

The 81-piece sets provide broad dimensional flexibility, letting users create an extensive range of reference lengths for setting and checking precision measuring instruments, comparative gages and inspection equipment. AS-1 serves professional dimensional inspection; Grade 0 is the premium option for aerospace, medical, automotive, defense and calibration customers whose requirements extend beyond ordinary workshop-grade blocks.

Calibration and Traceability

Gage blocks are the reference standards other instruments are set against, so their own calibration status governs the credibility of everything measured with them. WESTport provides ISO/IEC 17025 accredited calibration to keep a set documented and controlled over its working life.

Applications

Precision inspection departments, calibration laboratories and manufacturing quality operations — anywhere reference lengths must be built to a documented, traceable accuracy grade.
