Design
Workmanship
Our gage blocks are manufactured under carefully controlled conditions and inspected by the ASME B89.1.9-2002 standard, allowing for an accuracy of +/- 6 millionth for sizes under 1" block when used at room temperatures of 68 degrees Fahrenheit (or 20 degrees Celsius). The gage blocks are made of fully seasoned alloy tool steel and hardened to 65 RC to provide resistance to wear, abrasion, and rust. The inspections are conducted in an ISO-9001 certified laboratory with a master block set that is traceable to NIST, and each block's deviation is recorded on the NIST traceable calibration form.
Spotlight
-
Measuring Faces
The measuring faces (2 sides) are ground and micro-lapped to surface roughness of Ra 0.016 while the non measuring faces (4 sides) are maintained at Ra 0.63.
-
Laser Marking
Each gage block is laser marked with a nominal length and serial number with reference to the calibration certificate.
-
ASME B89.1.9-2002 Standard
Inspections take place in an ISO-9001 certified laboratory and each block's measurement is recorded on the NIST traceable certificate, not a ISO17025 long form certificate.
-
Plastic Insert
Each block is placed inside a plastic insert holder to prevent corrosion and abrasion.
