  • Mill Bolting BoltPrep

    This process involves taking an unstressed or loose bolt reading on the bolts before they are tightened, the correct load as specified by the mill and liner bolt manufacturers is calculated into an elongation length, then the bolts are tightened until the required elongation is achieved. This technique guarantees that your bolts have been tightened to the correct load.
