Lag Screws For Wood Vs Structural Screws

Lag screws are used when you need a strong joint that can withstand significant stress. They are longer and thicker than other types of screws, and they have a hexagonal head that provides extra strength. This makes them ideal for holding heavy items and structures together. Lag screws are often used in applications like pole line utilities, retaining walls, deck frames, and outdoor play equipment where there are heavier load requirements than your typical wood screw can handle.

Unlike standard wood screws, which use coarse threading that doesn’t usually extend to the head, lag bolts have threads that extend all the way up to the head. They also require pre-drilling to prevent the heads from snapping off under too much torque. However, new innovations in self-tapping wood screws are beginning to replace lag bolts in many of the same heavy-duty applications that were traditionally reserved for lag screws.

Structural screws, for instance, are easy to install and can withstand much more weight than conventional lag bolts. They also have a wider bearing surface and are easier to drive in with your drill. As a result, they can cut labor costs for builders by allowing them to use fewer tools and save time.

So, which type of fastener should you choose for your next project? The answer depends on the specifications of your specific job. If you need a screw that can withstand high loads and is easy to drive in, then go with a lag screw. On the other hand, if you need a screw that can be driven in without using a socket attachment and does not require any pre-drilling, then a structural screw is a better option. lag screws for wood
