Gauge & Angle Block Sets

A gauge block set is a system for measuring length to a high degree of accuracy. This is achieved by stacking multiple blocks together. Each gauge block is ground to a precise thickness, and sets contain a range of standard sizes.
To combine gauge blocks and create a broader variety of lengths, you slide two blocks against each another. This process is called wringing and it makes the ultra-flat surfaces of the gauge blocks grip together.

What are gauge block sets used for?
Gauge block sets can be used to create a broad range of precise measurements. In manufacturing environments or machine shops they're used to calibrate the accuracy of devices in other measuring sets, such as calipers. They're the recognised standard measures of length in industry.

Types of gauge block set
The main way gauge block sets vary is in the materials they're made from. This depends on what your priorities are as a user.

  • Steel is hardened and tempered to reduce the rate of wear. It's suitable for standard usage.
  • Chromium carbide and tungsten carbide ceramic are more durable and longer-lasting than steel. They're often used for calibration.
