WebThe pull-out strength of a wood screw is going to be more dependent on the wood into which it is installed than on the material of the screw. The geometry of the screw thread also plays a role. "Cheap" screws therefore aren't what you need to worry about, instead, focus on the screw size. Pull-out happens when you have a shear failure of the wood. WebA lag screw can have as much as a nine times greater bonding factor to wood than a regular nail. If a lag screw with a 5/16-inch shaft is installed correctly, it can withstand pull-out, or …
