HNS Series Compact Angled Hydraulic Nut Splitters
Engineering Overview & Structural Features
The HNS Series Compact Angled Hydraulic Nut Splitters provide fast, spark-free, and safe splitting of seized, rusted, and frozen nuts without damaging underlying bolt stud threads. Operating at 700 Bar (10,000 PSI) with single-acting spring return, the HNS Series delivers splitting forces from 5 to 90 Metric Tons across 13 to 75 mm hex sizes (M8 to M48). Its dedicated angled head profile provides optimal clearance on pipe flanges, structural joints, and compact machine bases where straight cutters cannot reach.
Compact & Easy to Use
Ergonomic, lightweight envelope engineered for fast single-operator handling, allowing effortless positioning onto frozen fasteners on offshore platforms, pipelines, and industrial refineries.
Fast Spring Return Retraction
Single-acting hydraulic cylinder with heavy-duty pre-loaded internal spring return mechanism ensures immediate blade retraction upon pressure venting for continuous, rapid cycle times.
Easy to Replace Cutting Blade
Precision tool-steel cutting chisel can be quickly re-sharpened or swapped out on site with simple hand tools, maximizing uptime during emergency turnaround maintenance.
Angled Head for Clearance
Dedicated angled cylinder-to-head geometry allows the tool body to tilt away from adjacent flange faces and pipe walls, ensuring flush blade seating without physical interference.
OEM Cross-Reference & Dimensional Interchangeability
Compact angled hydraulic nut splitters delivering 5 to 90 Ton cutting force across 13 to 75 mm hex sizes with single-acting spring return. 5 - 90 Ton / M8 - M48 (13 - 75 mm Hex).
