Preparation Steps

1. Choose the Right Carriage Bolt:

   Size	Application
   1/4 inch	Light projects such as attaching a small bracket
   5/16 inch	Medium projects like furniture assembly
   3/8 inch	Heavy-duty applications such as deck building

2. Gather Necessary Tools and Materials: Be sure to have the following on hand:
   • Carriage bolts
   • Washers and nuts
   • Drill with appropriate drill bits
   • Wrench or socket set
   • Pencil for marking
   • Measuring tape
   • Wood glue (optional)
3. Measure and Mark: Accurately measure where you want to install the carriage bolt. Influencers like Matt Risinger emphasize the importance of making precise marks to ensure fit and alignment.

Drilling the Holes

1. Select the Right Drill Bit: Use a drill bit that matches the diameter of the carriage bolt's shaft. For example, a 1/4 inch bolt requires a 1/4 inch drill bit.
2. Drill Pilot Holes: Always start with a pilot hole to prevent the wood from splitting and to make inserting the bolt easier.
3. Drilling Technique: Use a steady hand and moderate pressure while drilling to ensure a clean hole. Deepen the hole to accommodate the bolt length. Influencer and carpenter April Wilkerson suggests checking the depth frequently.

Installing the Carriage Bolt

1. Insert the Carriage Bolt: Place the square section of the bolt into the hole first. This should sit flush against the wood surface.
2. Add Washers and Nuts: From the opposite side of the wood, add a washer and then screw on the nut. The washer helps distribute the load and prevents the nut from digging into the wood.
3. Tighten with a Wrench: Use a wrench to tighten the nut securely, but be careful not to overtighten, which could lead to potential wood damage.

Finishing Touches

1. Cutting Excess Bolt: If the bolt protrudes too much, use a hacksaw to cut off the excess length, ensuring the installation is flush.
2. Sanding Smooth: Sand down any rough edges around the hole to ensure that there are no splinters or sharp edges.
3. Sealing (Optional): To further protect your wood and fastener, apply a wood sealer or finish to match the surrounding wood.
