STAVI SCREW
The STAVI SCREW is a screw-type earth clamp rated at 600A. Instead of relying on spring pressure, the screw spindle is tightened onto the workpiece, which gives a fixed, high-pressure contact that will not shake loose during heavy or long-duration welding.
Product details
Key Features and Benefits of STAVI Screw Earth Clamp
- Screw-Down Clamping: Spindle pressure gives a fixed contact that will not vibrate loose.
- 600A Rating: Rated at 600A with 3/0 (95mm²) cable capacity.
- Jaw Opening to 63mm: Clamps sections up to 63mm (2.5in).
- Brass Construction: Brass body combines conductivity with resistance to wear and corrosion.
- Set-and-Forget Earth: Suited to long jobs where the earth point stays in one place.

Frequently Asked Questions
What is the STAVI SCREW earth clamp used for?
The STAVI SCREW is a 600A screw-type welding earth clamp designed to provide a fixed, high-pressure electrical connection to the workpiece. It is suitable for manual arc, MIG and TIG welding, fabrication, structural steel, pipe work, maintenance and repair applications.
What is a screw-type welding earth clamp?
A screw-type welding earth clamp uses a threaded spindle to tighten the clamp directly against the workpiece instead of relying solely on spring pressure. This provides a firm, fixed connection for welding applications where the earth point needs to remain securely in position.
What are the benefits of using a screw-down earth clamp?
Screw-down clamping provides high contact pressure and helps prevent the earth connection from loosening due to vibration or movement. This makes the STAVI SCREW particularly suitable for heavy-duty and long-duration welding where a fixed earth point is preferred.
What is the amperage and cable capacity of the STAVI SCREW?
The STAVI SCREW is rated at 600A and supports 3/0 (95mm²) cable capacity, making it suitable for high-current welding applications.
What is the maximum jaw opening of the STAVI SCREW?
The STAVI SCREW has a maximum jaw opening of up to 63mm (2.5in), allowing it to clamp onto relatively thick sections and workpieces.
Is the STAVI SCREW suitable for long-duration welding?
Yes. Its screw-down spindle provides a fixed, high-pressure contact designed to remain secure during vibration and extended welding operations. The brass construction also provides conductivity and resistance to wear and corrosion.
