Technical SupportWe're here to help

The large-bore Enerpac NSH-Series splits seized and corroded nuts from M45 to M90 without grinding or flame cutting. A complete nut splitter is a cutting head (NSH) plus a power head (NSPH single-acting, or NSPH-D double-acting for subsea). The blade positioning scale presets the cutting distance so the bolt thread is not damaged as the nut is cut. All NSH cutting head and NSPH power head combinations are CE–ATEX certified.
