Precision Steel Gage Block Sets for Accurate Measurements
A Steel Gage Block Set, also known as a slip gauge or Johansson gauge, is a collection of highly accurate, precision-ground blocks used as a reference standard for dimensional calibration. Each block is manufactured to a precise length and can be stacked to achieve a wide range of measurements.
Made from stabilized, hardened steel, these blocks resist wear and deformation, ensuring long-lasting accuracy. They’re widely used in inspection labs, tool rooms, and calibration environments for verifying micrometers, calipers, and other measuring instruments.
Key Features of Steel Gage Block Sets
High Accuracy
Precision-made for exact measurements.
Durable Steel
Hardened for long-lasting wear resistance.
Stable in Temperature
Maintains accuracy in varying conditions.
Smooth Finish
Allows easy wringing and minimal error.
Applications of Steel Gage Block Sets
- Dimensional Calibration Labs: For calibrating measurement tools and instruments.
- CNC & Precision Machining: Tool setup and machine alignment.
- Quality Control: Verifying part dimensions and tolerances.
- Metrology Standards: Establishing measurement traceability.
How to Use Steel Gage Blocks sets
- Wringing: Carefully slide and press two blocks together until they adhere via molecular attraction.
- Build Stack: Combine blocks to create the desired measurement length.
- Measurement Setup: Use the gage stack as a standard to calibrate or verify measuring instruments.
- Store Properly: After use, clean and oil the blocks to prevent corrosion.
