Things You’ll Need

There are few things we should consider before starting the process of how to attach wood to metal with screws:

Screws:

Screws are very important to connect and fasten the wood pieces to each other and other things. They are especially important in learning how to attach wood to metal. There are some special screws that fasten the wood with metal structures. These screws tightly hold the wood and metal pieces together even under pressure.

Sheet Metal Screws:

Screw metal sheets to wood and other items. Use a socket hex head screwdriver to fasten wood pieces to metal. Drill the sheet metal screw into wood and metal by using the socket bit on a drill. Use slightly longer screws than width or thickness of the material and run the drill at maximum speed.

Lag Screws

Lag screws fasten metal to wood pieces together. Drill a pilot hole in wood and metal before placing a washer on the top part of the hole and a lag screw through the metal, wood and washer. The washer reduces the pressure on wood to prevent breaking and cracking.

Screwdriver (Socket Hex Head)

How To Attach Wood To Metal Without Screws

The answer to the question of how do you attach wood to metal without screws is using rivets. The process of attaching needs a drill, perfect size rivets, a rivet gun, and a washer for each rivet.

• Pre-drilling holes is important to prevent splitting or damaging the materials. So, mark rivets location on wood and metal. Drill holes of the same diameter as rivet shank.
• Place the washer on the shank of the rivet before inserting it into the hole. The washer helps in distributing load and preventing rivet head from pulling through the metal.
• After inserting the rivet into the hole, set the rivet by using a rivet gun. The gun pulls mandrel out of rivet, thus expanding the head of the rivet and creating strong bond.
• Remember, attaching wood to thin metal, like sheet metal, needs backup plate to prevent metal from deforming when the rivet is set.

In the end you will get a strong and durable bond like one in Post and beam construction by using structural rivets.

How To Attach Wood To Metal By Welding

The answer to the question of how to attach metal to wood without screws or glue is welding. Attaching wood to metal by welding is a strong and durable method but needs expert handling. The welding process involves high heat generation which can ignite wood and cause big damage. Let’s see how to attach wood to metal by welding safely:

• Welding rods are different for different metals welding. Carefully choose the welding rod which is compatible with both wood and metal like nickel-based rods named AWS 5.8/ERNi-Cu7.
• Prepare wood and metal surfaces by removing dirt, rust, or paint with brush and remove oils or grease with a de-greaser.
• Take clamps, magnets, or tack welds and secure wood and metal in place before welding. Securing prevents wood from moving or warping during welding.
• Select low heat settings and start welding the perimeter of joint. After perimeter welding, you can fill in the center of the joint.
• After the welding process, let it cool down before moving the joint, otherwise, the weld will crack.
