Gauge (or Gage) blocks are precision-ground, rectangular or square blocks made from high-quality steel, ceramic, or other materials. They are manufactured to very precise dimensions with extremely tight tolerances. Gage blocks come in various sizes, and they are used as building blocks to create precise measurement standards. By stacking gage blocks together in various combinations,...

A surface plate, is a large, flat, precision tool used as a reference surface for measuring and inspecting the flatness, straightness, parallelism, and other geometric features of workpieces. Surface plates are an essential part of precision measurement and quality control processes in various industries, including manufacturing, engineering, and metrology. Surface plates are commonly made of...

Pin gauges, also known as pin gages or gauge pins, are precision tools used to measure the diameter of holes or to check the spacing between surfaces with high accuracy. They are cylindrical rods, typically made from hardened steel, carbide, or other wear-resistant materials, and are manufactured to extremely tight tolerances. Each pin gauge has...
