A lag screw is used to bond two or more pieces of lumber and enhance the structural strength of log cabins and other similar structures. A typical lag screw has thick shaft with large threads designed to provide strong hold on the wood. Lag screws vary in sizes and lengths so if you want to use lag screws for your construction, you should get screws that are long enough to hold your logs together. To determine the length of the lag screws for your construction needs, here is what you should do.

Step 1 – Measure the Thickness of Your Lumber Materials

You need to check the thickness of your lumber materials in order to get an idea as to the size and length of the lag screws that you need to connect the logs together. To do this, use a ruler to measure the thickness of the log then record the figures on paper. If your logs vary in sizes, get the average thickness of the logs and use this figure as your guide in selecting the right lag screws.

Step 2 – Buy Your Lag Screws

After taking the measurements of your lumber materials, you may now buy your lag screws.
