Lag bolts and tips on installing them properly

A lag screw also known as lag bolt can be considered an inexpensive concrete anchor which can be used in various materials for creating structural integrity where ever it is required most. When this lag bolt is applied it is known to take the brunt of the weight lessening the burden on the structure. They are often used on patios, porch swings, entertainment centres, etc. These screws are massive in comparison to other normal screws and come with typical hexagonal heads.

These bolts have been in use since several years mainly for joining large pieces of lumber. They work differently from other screws; they burrow in with coarse threads and create a sort of friction joint. Working with the right drill bit for the shank size and a different bit for the thread is what leads to a strong and permanent lag bolt joint.

Lag Bolts

What are lag bolts used for?

Lag screws are in some ways similar to other screws and are used to hold things together. These bolts are monstrous when compared to screws such as wood or sheet metal screws and the starting size is usually 1 inch in length and ΒΌ inch in thickness.

Lag Bolts are typically used when heavy loads are to be borne. They mainly are sued for connecting timber used in the house and are also used for building decks, fixing TV screens on the walls, and any other things that need heavy support.

Tips for proper application of a lag bolt

Never use lag bolts that are not proportionate to the material you wish to work with; example do not use a lag screw 8 inches long with material that is 7 inches thick.

Measure the materials you wish to join and ensure the length of the screws are not more than half of the total thickness of the materials you are working on.

Also ensure that the lag screws are not too thick since they can splinter the material.

Always use a pilot hole that is to be drilled into the material for serving as a guide for the screw to avoid it going off course or splintering the material.

See that the hole drilled is smaller than the diameter of the lag bolt for making it more effective.

Use the appropriate tools such as a drill with proper attachment and an electric screwdriver. For the hex head you need a hexagonal bit for installing, tightening or removing; though a pliers or a wrench can do the job it will not be as secure.

It is always better to install the lag bolt in one quick burst to prevent it from wobbling or splintering the wood.

And for installing a lag bolt align the materials you wish to join and clamp them. Drill a hole through the materials you want to send the screw through. Put a nut on the other end of the screw for evenly spreading the weight it bears along the shaft. Finish tightening the screw using a right driver bit.

Once the lag bolt is secure you can remove the clamps; job well done!
