Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness.

Use these tight-tolerance blocks as mounting bases and supports to ensure accurate angles and spacing. Choose from our selection of jo blocks, including gauge blocks, Mitutoyo gauge block sets, and more. Same and Next Day Delivery.

Mar 4, 2024 · Gauge blocks, also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks, constitute a precision length production system. These blocks, crafted from metal or ceramic, undergo meticulous grinding and lapping processes to achieve specific thicknesses.

Gauge blocks and sets are commonly stacked together to make a desired length. Rectangular gauge blocks, also known as Jo blocks, are made of metal or ceramic. They have two opposing faces that are ground flat at an exact distance apart.

Gauge blocks, also known as slip gauges, are rectangular (also known as Jo blocks) or square blocks (also known as Hoke blocks) of metal or ceramic with two opposing faces that are ground precisely flat and parallel at an exact distance apart.

Jun 30, 2010 · The Mitutoyo 516-series Grade 0 Ceramic Square Inch Gage Block Set includes a set of square-shaped, white ceramic (CERA) gage blocks with nominal length engraved in inches on each, and is supplied with a Mitutoyo inspection certificate that states that the blocks meet American Society of Mechanical Engineers (ASME) B89.1.9-2002 grade 0 standard ...

Looking for gage blocks? They are also called Jo blocks, slip gages and Johansson gages. These useful blocks are often utilized when distances between parallel surfaces need to be measured and a reference for direct measurement of those lengths and widths become necessary.

Gauge blocks are rectangular (also known as Jo blocks) or square (also known as Hoke blocks) blocks of metal or ceramic built with two opposing faces ground precisely flat and parallel at an exact distance apart.

Oct 30, 2023 · Gage blocks are available in square or rectangular shapes. The rectangular gage block is the more commonly used Johansson design. Carl Edvard Johansson invented and patented gage block sets in 1896 to be used for length standards in machine shops. These rectangular blocks are also called “Jo-blocks” for that reason.
