Also known as a coach screw in the United Kingdom, a lag screw is a large metal screw — typically featuring a hexagonal head — that's designed for high-stress applications. While they are available in different sizes, most measure about 1 to 3 inches long and at least 0.25 inches thick. Of course, other screws have significantly smaller.

Lag screw tips must penetrate the house rim joist - that's at least ½ in. Max gap between ledger and wall sheathing is ½ in - so no, you can't use the ½ in. bolt with spacer option over the siding unless it's T 1-11. Bolts and screws must be located 2 in. down from top and up from bottom of ledger and staggered up-down.

11.4.1 Lag Screws and Wood Screws When a lag screw or wood screw is subjected to combined lateral and withdrawal loading, as when the fastener is inserted perpendicular to the fiber and the load acts at an angle, α, to the wood surface (see Figure 11F), the adjusted design value shall be determined as follows (see Appendix J): 22 (Wp)Z Z

In the case of a lag bolt, the threaded portion ends in a point. Moreover, comparatively, this part of the bolt is wider. And they have a hexagonal head and a round neck. They are also referred to as lag screws. Because they look more like a screw than a bolt. Carriage Bolts They are also known as plow bolts.

Lag screws require a pilot hole since they're not self-tapping or self-drilling. This is a two-step pilot hole: step one prepares for installing the shaft's threaded portion, while step 2 makes room for the unthreaded portion. As mentioned in a previous article, hexagonal heads are used when the application requires a high torque value.

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.
