Mitutoyo Steel Rectangular Gage Blocks

Mitutoyo steel rectangular gage blocks are precision reference standards for calibrating and setting micrometers, calipers, indicators, and other measuring instruments. They are also used for inspection and layout work in machine shops, tool rooms, and quality control labs. Also known as gauge blocks, slip gauges, or Jo blocks, they give you a dependable length standard for accurate dimensional measurement.

Key Features:

• Steel construction: Hardened, wear-resistant steel helps the blocks keep their accuracy through repeated use.
• Rectangular profile: The shape gives stable, flat measuring faces and makes the blocks easy to handle and stack.
• Precision lapped faces: Flat, parallel measuring surfaces let the blocks wring together tightly. This allows you to build up custom stack heights.
• Graded accuracy: Each block is manufactured to a specified accuracy grade. Choose the grade that suits your calibration, inspection, or shop-floor needs.
• Mitutoyo quality: Mitutoyo is a leading maker of precision measuring tools and metrology equipment, and is trusted worldwide.

Common Applications:

• Calibrating and verifying micrometers, calipers, and dial indicators
• Setting sine bars, height gauges, and comparators
• Machine setup and precision inspection
• Tool room and quality lab reference standards

For best results, keep the blocks clean, handle them with care, and store them protected from corrosion and damage. Choose the individual gage block you need from the available options.
