What is a Rigging Screw?

A turnbuckle (also called a bottle screw or stretching screw) is a mechanical device used to adjust the tension or length of ropes, cables, tie rods, and other tensioning systems. It consists of two threaded eye bolts (or hooks/jaws) connected by a metal frame, typically with left-hand and right-hand threads. When you rotate the central body, the fittings move closer together (to increase tension) or further apart (to loosen).
