Abstract
Tests were carried out on domestic wood samples to modify the formula which had previously been developed to predict the withdrawal strength of screw on the face of lumber. Screw sizes were No. 6, 8 and 10 used in this study. Predicted equations were fitted to the results of different length of No. 8 wood screw. The withdrawal strength of screws was enabled to predicted as a function of screw diameter, depth of penetration, and specific gravity of wood. Predicted equation was under-predicted the withdrawal strength of 25 and 30 mm length of screw within 5% and over-predicted withdrawal strength of 18 and 38 mm length of screw.
