Turnbuckles

Turnbuckles are used in rigging to join wire-rope or cable to an anchor point or other length of wire. They have a screw thread for precise length and tension adjustment. Most turnbuckles are forged or cast from stainless steel or low carbon steel. They are machined to product specifications and then quenched, tempered, plated with zinc, or hot-galvanized. Products with self-colored finishes and yellow chromate coatings are also available. Stainless steel turnbuckles are designed for applications which require high strength-to-weight ratios and minimum turnbuckle diameters. They combine very high tensile strengths with ductility and corrosion resistance. Some cable turnbuckles are made of 304 or 316 stainless steel. Others use 1030 carbon steel. For all types of turnbuckles, there are several basic configurations: stub end, eye and eye, hook and hook, jaw and jaw, and jaw and eye. Stub end turnbuckles feature a steel rod that protrudes at both ends. Eye and eye turnbuckles have two circular or oval-shaped eyes. Hook and hook turnbuckles and jaw and jaw turnbuckles have either two hooks or two jaws, respectively. Jaw and eye turnbuckles are designed for specialized applications.
