Step 1: Measure your carriage bolt

At the very first, you need to measure the carriage bolt you have chosen.

For that, get a measurement tape and determine the diameter and length of the bolt you are using.

Step 2: Get the bolt sized drill bit

Getting the same sized drill bit as the carriage bolt is very important. If the size does not match, then you might not be able to install the bolt properly.

If you choose a larger bit for the drilling, then it will result in a loose bolt.

And if you choose a small bit, then you will not be able to put the carriage bolt inside the hole to fix. So, fix the accurate size of the bit to drill up the hole.

If you are making a hole in the metal surface, then you should coat the drill bit with cutting fluid. The coating will help to make the hole a lot easier way.

Step 3: Dig a hole with a drill machine

Next, you need to dig a hole into the material you want your carriage bolt to be installed. It is recommended to run the drill at a slower RPM.

The slower RPM helps to dig the hole smoothly in the harder surfaces. Besides, slowing up the drill will help you to get control over the drilling.

Step 4: Set the bolt into the hole using a hammer

You can slide down the carriage bolt into your drilled hole. The hole you have made by drilling can be slightly congested.

So, to avoid the problem of sliding the bolt into the hole, you can use a hammer to force the bolt in.

Just slightly tap the bolt with the hammer, and that will do the rest of the work.

Step 5: Put the washer and tighten up the bolt

After you have put the bolt into the hole, now it is time to complete the installation of the carriage bolt.

A washer needs to be placed on the opposite side of the bolt and the material. The bolt dome and the washer must be placed on the different sides of the material.

As you have installed the washer successfully, it is time to put the nut on it. Roll over a nut on the bolt and tighten that up using a wrench.

The square shoulder on the bolt will prevent it from spinning on the material.

The shoulder helps to make the carriage bolt stay strong on the elements and draw a strong bond.

The installation guide needs to be followed accurately to install the carriage bolt to any surface and to get the stronger bond between the different parts of the element.

Besides, the carriage bolts placement should be determined before drilling the hole out.

This way, you can ensure the perfect hole and also make the perfect joint in between the woods or metal parts.
