- Inspection use→Calibrating instruments→Grade 0
- Grade AS-1: These gage blocks are intended for shop floor use to set and calibrate fixtures as well as precision instruments.
- Grade 0: This grade is used within an inspection area to verify the accuracy of plug and snap gages as well as for setting electronic measuring devices.
- Sets calibrated to meet or exceed federal specification GGG-G-15C Grade 3(A+B).
- Set made of fully seasoned alloy tool steel with hardened to 65 RC to provide both long wear and resistance to stains and rust
- Blocks manufactured under carefully controlled conditions, allowing for the highest degree of accuracy when used at room temperatures of 68 degrees F (20 degrees C)
- Mirror polished surfaces provide superior wringing characteristics.
- Guaranteed Accuracy of Flatness, Squareness, and Parallelism
- Excellent Finish and Wringing Characteristics
- Professional treated gauge block wooden index box.
- All gage block sets are cleaned, reconditioned, and greased ready for shipment
- All sets are supplied in deluxe fitted wood case
- Grade AS-1 Steel Rectangle Inch Gage Block Set includes a set of Rectangle-shaped, high-carbon, high-chrome steel gage blocks with nominal length engraved in inches on each, and is supplied with a SHARS inspection certificate that states that the blocks meet American Society of Mechanical Engineers (ASME) B89.1.9-2002 Grade AS-1 standard for flatness, length, parallelism, and surface finish.
- High-carbon, high-chrome steel has a high hardness for minimum deterioration, and is selected for its wear-resistance. These gage blocks have a Rectangle base for accurate wringing, to attain a height reference standard, and for the ability to make a dedicated inspection jig. The nominal length of each block is measured in inches, and is indicated with laser-etched, black characters.
- An identification number is laser-etched on each block for traceability. The set includes an inspection certificate [National Institute of Standards in Engineering (NIST)-traceable] that the blocks meets ASME B89.1.9-2002 standard for flatness, length, parallelism, and surface finish.Gage blocks (also called gauge blocks, Hoke blocks, Jo blocks, slip gages, and Johansson gages) are blocks used to calibrate measuring equipment and to standardize the measurement of length in manufacturing industries.
- Gage blocks can be wrung together to create a required length. Wringing is the process of lapping blocks together with a small amount of oil. They are standardized by grade, which refers to the tolerance or deviation of an individual block from its nominal length. Gage block grades are defined for flatness, length, parallelism and surface finish. Some grades of gage blocks meet standards such as ASME, Association for Iron and Steel (AIST), and International Organization for Standards (ISO). Application and required level of accuracy dictate which grade of gage block should be used.
- Both a certificate of inspection and a calibration certificate specify the deviation from the nominal length.
