A true source of measurement, use these gauge blocks to calibrate measuring equipment, mark precise layouts, or position your fixture or machine components just right. All blocks include a certificate of compliance to certify their sizes are within tolerance. The certificate also lists when each block will require recalibration.
Each block has a grade per ASME B89.1.9. Grades are based on tolerance—the smaller the tolerance, the greater the accuracy.
Use a gauge block holder (not included) to create a custom repeatable measurement by stacking multiple blocks together.
Grade 0 Gauge Block—Grade 0 gauge blocks are our most accurate. They help verify that precise measuring instruments, such as micrometers and calipers, are taking accurate readings.
Steel—Steel blocks are the most common choice for gauge blocks.
