8-10T Heavy-Duty Tool Hydraulic Nut & Screw Cutter

When a rusted, seized nut refuses to budge, the JK Series Heavy-Duty Hydraulic Nut Splitter is the professional's answer. Available in two configurations — 14-ton (JK-27) and 20-ton (JK-30F) — this tool lineup is engineered for industrial environments where standard wrenches and impact tools have already failed.
The JK-27 handles M8 through M27 nuts with a 14-41mm hex range and 20mm stroke, making it the go-to choice for medium-duty pipeline, mechanical, and structural maintenance work. Step up to the JK-30F for the toughest applications: 20 tons of hydraulic force, a 26mm stroke, and coverage up to M30 with an 18-46mm hex range — built for heavy industrial, petrochemical, and offshore environments where larger fasteners dominate.
Both models share the same battle-tested construction: a 40CR chrome steel cutting head precision-wire cut to a semi-hexagonal profile that locks onto the nut securely before splitting. The three-layer sealed plunger eliminates oil leakage under sustained pressure, while the insulated handle protects operators in electrically sensitive environments. A simple relief valve switch — tighten to pressurize, release to return — keeps operation intuitive even under stress.
The ZG3/8" quick connector with dust cap (JK-30F) ensures a clean, fast hookup to any compatible hydraulic pump rated up to 70 MPa. No power source needed — pure hand-operated hydraulic force, deployable anywhere.
