Expansion Anchor Bolt Stainless steel Can be used multiple times
Stainless steel expansion screws are generally said that the metal expansion screws, the expansion of the screw is fixed using wedge-shaped slope to promote the expansion of the friction force, to achieve a fixed effect. Stainless steel expansion bolts are divided into: 45,50,60,70,80. Expansion screw by the screw and expansion tube and other components, the screw tail is conical, the inner diameter of the cone is greater than the expansion tube diameter. When the nut is tightened, the screw moves outward and moves the conical portion by the axial movement of the thread, thereby forming a large positive pressure on the outer peripheral surface of the expansion tube, and the angle of the cone is small, so that the wall, And the formation of friction between the cone self-locking, and thus achieve a fixed effect.
