A hose clamp having a self-threading hardened screw extending through outwardly extending tabs on the generally circular clamp, the head end of the screw fitting through a clearance opening in the first tab, and the screw threadably engaged with the second tab, the first tab being reinforced against bending by a deformation dimple at the juncture to the circular band, and the second tab being bendable upon screw tightening to cause the screw angle to change sufficiently for the screw threads to cut slots in the band, forming a worm-type drive engagement. |
