NettetLag bolts are especially suited for heavy timber construction as they have much larger tensile strength than wood screws, making them better for holding heavy objects in place. On the other hand, wood screws are designed to join two pieces of wood together. Nettet2. jun. 2006 · I believe that the lag bolts could add enough additional holding power to compensate for the distance of 5/8" and the fact that drywall has no load bearing capability. The compression afforded by the lag bolts and the fact that they would have much more bearing capacity than 16p nails could help.
