Straining Screws

Straining screws (also known as riggingscrews) are a simple piece of equipment used to adjust the tension of wires or to secure loads.

How do straining screws work?

To use a straining screw, you attach the wires than need to be tensioned to the fittings at either end. Rotating the body of the straining screw pulls the ends towards one another, causing the wire to tighten, or away from each other, causing it to loosen. This piece of equipment can have different ends depending on your needs – hooks, eyes or jaws, or a combination of two of these. Jaws usually have pins to keep them securely in place.

What are straining screws used for?
