The possibility of transmission of axial forces between self-tapping screws fastened in the opposite faces of a timber element and loaded contrariwise is analysed. The screws are intended to be placed sufficiently close one to another and the threaded shanks overlapped by a suitable length. Experimental tests are conducted, varying type, penetration depth and overlapping length of the screws, to evaluate the actual strength and the type of failure of this fastening technique.

Abstract
The possibility of transmission of axial forces between self-tapping screws fastened in the opposite faces of a timber element and loaded contrariwise is analysed. The screws are intended to be placed sufficiently close one to another and the threaded shanks overlapped by a suitable length. Experimental tests are conducted, varying type, penetration depth and overlapping length of the screws, to evaluate the actual strength and the type of failure of this fastening technique.File in questo prodotto:
