how to hold the bolt size of the coal mill
Grade 8.8 Bolts
It is possible to improve the strength of this alloy by the use of certain surface treatments. Most common amongst all surface treatments is galvanization, where zinc is used to coat the 8.8 Bolt Material. Galvanization coats the bolt with a much thicker layer of zinc in comparison to electroplating or coating.

12-11-2019Use a bolt diameter that is 1.5 – 2.5 times (up to three times) the thickness of the thinner material you are bolting together. So, for 1/8″ material, a 1/4″ diameter is often a good bolt choice. For 1/4″ thick material, perhaps a 3/8″ or 1/2″ bolt. This guideline falls apart for very thin materials, and for really thick stuff.
