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.
