What are the differences between a lag screw and a lag bolt, and how do these differences impact their respective uses in construction projects?

A lag screw has a pointed tip and is threaded along its entire length, while a lag bolt has a flat tip and is partially threaded. Lag screws are typically used for wood-to-wood connections, while lag bolts are more suitable for attaching metal hardware to wood. The differences in their design impact their holding power and the types of materials they can effectively fasten in construction projects.
