Description
Urko hydraulic screw clamp 350 x 80 mm 8000 N is a special tool that uses a hydraulic mechanism to achieve high clamping force. The product offers up to 8000 N (approx. 800 kg) of clamping force, which allows pieces to be clamped very tightly and securely. Thanks to the hydraulic system, the required force is reached with considerably less hand force than with traditional mechanical screw clamps, which reduces strain on the user and improves work efficiency in long-term use.
The maximum throat depth of this clamp is 80 mm and the maximum opening, i.e. jaw opening, is 350 mm. The body of the clamp is designed to withstand the high loads caused by hydraulic pressure without distorting. The sliding jaw moves smoothly on the bar, and the hydraulic handle lets you fine-tune the force to exactly the right level.
The clamp has an ergonomic handle that improves grip and makes pumping the hydraulic pressure easier. Jaw pads protect the surface of the workpiece from damage. A hydraulic clamping tool of this type is essential where exceptional holding force is needed in metalworking or woodworking.
Intended use:
- Gluing and clamping: Excellent for demanding woodworking gluing projects, such as assembling solid wood tops or furniture. The high 8000 N clamping force ensures tight glue joints along the whole length of the joint.
- Metalworking and clamping: Can be used to clamp metal pieces firmly during welding, drilling or grinding. The hydraulic force stops the pieces moving during work, which improves safety and accuracy.

Urko hydraulic screw clamp instructions for use:
Before use, make sure the clamp is clean and the bar moves freely. Place the clamp around the workpiece and move the sliding jaw close to the surface. Pump the hydraulic handle until the clamp touches the surface and the required clamping pressure is reached. Do not exceed the stated maximum force. After use, release the pressure by pressing the release valve or lever (depending on the model) and pull the jaw open. Keep the bar clean of dust and glue residue to ensure smooth operation. Lubricate moving parts lightly with oil if necessary.
Warnings:
- Do not use the clamp if it is faulty or shows signs of hydraulic leaks.
- Always wear safety glasses when working on clamped pieces.
- Make sure the clamping is secure before starting work.
- Do not leave hydraulic pressure on unnecessarily for long periods.
- Keep out of the reach of children.
- Use only for the intended purpose, not for lifting or pulling.
Frequently asked questions (FAQ):
- What is the advantage of a hydraulic screw clamp?: The biggest advantage is the ability to produce a very high clamping force (8000 N in this model) with considerably less hand force than a traditional clamp with a mechanical threaded spindle.
- Can this clamp metal?: Yes, the 8000 N force is excellent for clamping metal pieces, for example during welding or machining.
- Does the clamp need maintenance?: The main maintenance is keeping the bar clean. The hydraulic system is usually sealed, but it is a good idea to keep an eye on its tightness. Moving mechanical parts can be lubricated lightly if necessary.
- Does the high force damage wood surfaces?: The clamp has jaw pads, but 8000 N is a very high force. It is advisable to also use scrap pieces to spread the clamping force over a wider area when clamping soft woods.
Recycling instructions:
The cardboard parts of the packaging should be recycled in cardboard collection and any plastic parts in plastic collection. The clamp itself is metal with mechanical/hydraulic parts. A product taken out of use should be taken to metal recycling. If hydraulic oil leaks from the clamp, it must be handled as hazardous waste according to local regulations.
