Grade 2 (A+) +000004″/-000002″

• Higher degree of accuracy when used at temperature of 68F (20C)
• Individual serial numbers on each block, regardless of grade.
• A complete certificate of calibration traceable to the N.I.S.T. showing the deviation of each block.
• All sets are supplied in deluxe fitted wood case.
• Mirror polished surfaces provide superior wringing characteristics.

• Tungsten carbide resists high corrosion, making it ideal for continuous handling, also with low coefficient of expansion to resist temperature changes or “hot hands” from the gage block users.
• With a surface finish of less than .2 millionths (.005 microns) is ensured and gives maximum wringability which is appreciated by users of steel and chromium carbide gages.
• The surface finish process removes all peaks, leaving mirror finish surface resistant to wear, ensuring long life within the original accuracy tolerance and retained wringability
• Edges of gaging faces are reinforced for a smooth radius
