Want to know what ASTM Block IDs really mean? We can help! Let's use 7075-5-0300 as an example...

  • The '7075' is the material the block is made from. This could be 4340, 304, 6AL4V, and so on.
  • The '5' is the flat-bottom hole (FBH) diameter in 64ths. This example block has a 5/64" diameter FBH.
  • The '0300' is the metal travel distance. Place an imaginary decimal point after the 2nd number, and that will give you the MTD in inches. This example block has a 3.000" MTD.
