Abstract
This specification covers swaged welded, cast, or forged turnbuckles with and without jam nuts. A turnbuckle is an internally threaded loop or sleeve intended for assembly with a threaded
stud, eye, hook, or jaw at each end, used for applying tension to rods, wire rope, and so forth. Turnbuckles shall be of the following types and grades: Type I (forged, spread, resistance
welded and arc or gas welded); Type II; and Type III. Turnbuckles shall be of the following classes; Class A; Class B; Class C; Class D; Class E; Class F; Class G; and Class H. The following
tests shall be performed: proof test; breaking strength test; bending test; and galvanizing test.
