Getting the Most Out of Lag Bolt Sizes


There are a lot of different types of bolts and screws out there, but knowing the right one for each project is crucial. For instance, a carriage bolt might be great for hanging your flat screen TV in the bedroom, but it’s not going to cut it when it comes time to put up a deck or build a fence. That’s where lag bolts come in—they’re designed to hold up against some serious pressure, so they’re the ones you want to use for projects that require more strength.

Lag bolts are similar to regular wood screws in that they’re thread-forming and do not need nuts to be tightened. Instead, they work by burrowing into the wood with their coarse threads and creating a type of friction joint. This is what makes them so strong. In fact, a well-made lag bolt can support up to 200 pounds or more depending on the diameter and length of the bolt.

In order to get the most out of your lag bolt, you’ll need to properly predrill and install it. It’s also essential to choose the correct size of lag bolt. This can be a tricky task as there are a variety of head shapes, lengths and diameters.

The most common types of lag bolts are hex head and square head. Hex head lag bolts are more commonly used because they’re easy to grip with a wrench. They have six-sided heads and are ideal for wood materials, as they feature thick spillways that keep them from slipping or loosening over time. They’re also a great choice for many home renovation projects, such as hanging a new flat screen TV.

While hex head lag bolts are an excellent option for most applications, there are other styles of lag bolts that can be used in certain situations. For example, some lag bolts are designed to be used in concrete or masonry structures. These types of lag bolts are called lag screws and are a little bit more expensive, but they’re perfect for heavy-duty projects like building a shed or attaching wood to steel.

Another great type of lag bolt is the fully-threaded hex lag screw. These are designed to be used in glulam beams and are often several feet long. They’re typically a little more expensive than hex head or square head lag bolts, but they provide extra strength and help prevent the laminations of a glued laminated beam from separating over time.

When it comes to choosing the right lag bolt size, you should start by measuring the combined width of the two pieces that need to be joined together. Then, select a lag bolt that’s about 1/4 inch shorter than the combined width. This will ensure that the lag bolt creates a proper connection without adding unnecessary strain to your project. Also, be sure to take into account any other construction tools or fasteners that may need to be installed along with the lag bolt.  Lag Bolt sizes
