Description DNV rules for ships/ High Speed light craft, Issue Jan 2001 Point 4 Chapter 3 Section1 F202, establishes that standard height adjusters are not acceptable for leveling, due to cyclic bending moments that the studs and bolts are subjected to. This is the reason why leveling of mounts using shims beneath the mounts is the only recommended method for leveling. Our Height Adjuster – Hi Sec also share also this method and that is the reason why shims have been developed. In order to achieve a fine leveling Hi-Sec height adjusters allow a final precise adjusting with security. Type H(mm) M1 M2 ADJUSTABLE(mm) MILLING HEAD NORDLOCK COMMERCIAL SCREW D.A.F.
