Corrugated fixing

Metal fixings designed for jointing timber. They consist of a metal corrugated section which is sharpened along one edge. They are simply hammered into two adjacent sections of timber forming a bridge between them. Large versions frequently used on roof truss assemblies, and very small ones often used to reinforce mitre joints on picture frames. The corrugation adds stiffness to the fixing such that it does not bend or fold while being hammered.
