HMNS Range

The HMNS range of hydraulic nut splitters offers a choice of 3 models suitable for hexagon nut AF sizes from 11/16" to 2" (1/2" to 1 1/4" bolt sizes). All models have an angled body design to provide the necessary clearance on flanges and flat surfaces. The revolutionary design incorporates a hardened steel linkage that ensures the blades cutting edge is kept parallel to the nut throughout the splitting process which improves operational efficiency and more importantly, blade life. Designed to easily split corroded nuts up to RC44 hardness, Hi-Force nut splitters offer the ideal ‘cold cut’ solution for removing worn or corroded fasteners, especially in applications where ‘hot work’ permits are not allowed. All models incorporate an integral hydraulic pump with multi-positional lever for even greater versatility.
