off. This paper shows a pullout strength of screw bolt by thickness of C channel. Pullout strength must be sufficient to resist the allowable tension of the fastener used in a tension connection. It depends on the metal alloy being fastened, the allowable shear stress of the metal, the fastener size and number of threads per inch, the internal thread stripping area, and the length of fastener engagement. Accordingly, in this study, the pullout strength is increased for increasing thickness of C channel. The load deformation curve of all examination body is similar.
