Removing Carriage Bolts: A Simple Guide

The Setup

Before diving into the process of removing carriage bolts, it’s crucial to ensure that you have the necessary parts and tools at hand. To complete this task, you will need:

  • Hammer
  • Drill
  • Drill bit
  • Piece of wood
  • Carriage bolt
  • Nut
  • Washer

For this example, let’s assume that we have already pre-drilled a hole in a 2×4 piece of wood and secured it to the vice. This will serve as the installation surface for our carriage bolts.

Understanding Carriage Bolts

So, what exactly is a carriage bolt? Well, it’s a bolt with threading all the way up the shank to a small square shoulder, topped off with a domed head. The square shoulder plays a crucial role in preventing the bolt from rotating as it is screwed into the surface of the material. It’s worth noting that this type of bolt is not typically used on very hard materials, as it may not dig in properly, causing the bolt to spin. Once the bolt is passed through the hole, the nut and washer come into play, ensuring that the bolt is tightly secured to the material. Since the half-round head lacks a drive mechanism, this is the only installation method.

Installation Process

Installing carriage bolts is a breeze. First, you’ll need to drill a hole in the wood that matches the size (diameter) of the bolt. Once the hole is ready, slide the bolt into it (you may need a hammer to assist if the fit is snug enough).

Now that the bolt is through the wood, it’s time to attach the nut and washer. Position the washer on the nut, behind the bolt. The washer serves to distribute the force you’re about to apply when tightening the nut, ensuring that the bolt is pulled securely into the wood. Not only does this protect the backside of the wood, but it also prevents the bolt from digging in and causing any jams.

When you tighten the nut, the square shoulder on the bolt will be pulled into the wood. Once the underside of the headrests on the wood, you can consider the carriage bolts officially installed.

Removal Process

Removing carriage bolts is a relatively simple process. Begin by loosening the nut, but don’t completely detach it from the bolt just yet. You’ll need it to help move the bolt along.

Once the nut is retracted to the end of the bolt, give it a gentle tap with a hammer. The force should push the square shoulder out of the wood. As you push the bolt out, the nut will get closer to the wood. At this point, step back from the nut and give it another hit. Repeat this process until the bolt is loose enough to be removed by hand or until the nut can no longer grip the bolt.

If you encounter a stuck bolt where the nut can no longer hold onto it, use the nail remover on a hammer to pry the bolt out of the hole.
