3 Common causes of bolt failure | Boltstress Ultrasonics

3 Common causes of bolt failure. Most mill operators are familiar with (and regularly go through) a process known as re-torque. Re-torque is an expensive exercise resulting in lost production, but is believed to be necessary in order to avoid bolt failures that cause unplanned shutdowns. It doesn''t have to be this way however, by eliminating
