Turnbuckles, also known as stretching screws or bottle screws, are devices used to adjust the tension or length of ropes, cables, tie rods, and other tensioning systems. Turnbuckles in this selection consist only of the open frame or body of the turnbuckle; no end fittings included.
Turnbuckles should only be applied in a straight, in-line manner only. Keep in mind that the larger the thread diameter of the end fitting, the more load capacity the turnbuckle will have. The longer the length of the turnbuckle body, the more slack it can take when tightening or loosening the turnbuckle.
Sizes listed as: Diameter - Thread Pitch x Take-Up Length
