The mechanical behaviours on turnbuckle sets of stainless steel(SUS304) was made clear by structural tests. Bolts, Six types of turnbuckles (Frame type A,B,C, Pipe type D,E, Slit type F), hagoita-bolts and turnbuckle body-bolt sets are tested. As the results of test, the following things was made clear. M10, M12 bolts are inferior in deformation ability because of the process hardening. The Pipe type bodies(D,E) had the residual deformation after allowable stress for temporary loading. The breaking points of slit type bodies(F) show tendency to be at the shoulder, because the effective section area at the part of the shoulder is less than that of lane. The rate of the deformation of the bolt frame on the level of the maximum strength of the bolt screw, to the maximum deformation is 10-20% on M10, M12, and 35〜55% on M16, M20, M24.
