The Mitutoyo 516-404-26 steel square gage block set has the following specifications:

• Number of Blocks: 81 Pieces
• Grade: AS-2
• Material: Steel

The 81 Piece Square Gage Block Set is made up of the following blocks:

• 9 Blocks: .1001-.1009″ (.0001″)
• 49 Blocks: .101-.149″ (.001″)
• 19 Blocks: .05-.95″ (.05″)
• 4 Blocks: 1-4″ (1″)

Features:

• Available in steel and ceramic (CERA) block sets with multiple blocks per set options
• Available grades includes 00, 0, AS-1, AS-2
• Specific, repeated heat treatment of steel blocks reduce deterioration change over time
• CERA blocks are free from dimensional change over time; have 10 times the abrasion resistance of steel gage blocks
• Ceramic blocks are adopted for frequently-used blocks. Ceramic gage blocks will last longer than steel gage blocks as well as not corrode.
• Advanced lapping techniques achieve the best flatness, surface roughness needed for gage blocks
• Black characters on gage blocks are inscribed by laser and clearly visible
• Square base for accurate wringing
• Nominal length indicated with laser-etched, black characters
• Provided with Inspection Certificate
• Supplied in a solid wooden case

The Mitutoyo 516-404-26 Square Gage Block Set can be used on a wide range of application measurements and will retain stable longitudinal and lateral orientation. The Mitutoyo Inch Square Gage Block Sets offer exceptional precision and great versatility for a wide range of measurement applications including cutting tool positioning, angle measurement with a sine bar, taper measurements with a roller, and inspection of depth micrometers. The square gage block retains stable orientation both longitudinally and laterally, and they are available in different grades, sizes and steps. The Mitutoyo innovative lapping technique makes our gage blocks some of the most accurate and trusted instruments in the world, featuring exceptional flatness and ideal surface roughness. Our steel gage blocks are constructed of high-carbon and methodically heat treated repeatedly for a high degree of hardness to reduce deterioration over time. The CERA gage blocks are constructed of ceramic materials with superior surface qualities and corrosion resistance for exceptional durability and reduced deformation.
