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.

Note: ASTM Blocks in aluminum and steel are not recommended for long-term immersion. If blocks are intended for this purpose, please contact Technical Sales to discuss industrial coating options.
