Structural Connection Design for the Home Inspector

The allowable withdrawal design strength of a lag screw is greater when the screw is installed in the side rather than the end grain of a member. However unlike the treatment of nails the withdrawal strength of lag screws installed in the end grain may be calculated by using the Ceg adjustment factor with the equation above.

Investigation on withdrawal resistance of various screws in .

Withdrawal resistances of screw and nailed joints of WPC have been evaluated by Chaharmahali et al.. They observed that withdrawal resistances of such joints are dependent on fiber content of WPCs containing waste fibers of MDF and particleboard. As filler content increased withdrawal resistance was lower than that of MDF panels.
