Clinch nails are used to fasten two pieces of wood together. The ideal clinch nail should be slightly longer than the combined thickness of the two pieces of wood being joined. This allows the tip of the nail to protrude and be bent back into the wood, creating a strong joint. The length of the nail is crucial, as nails that are too short cannot be clinched, and nails that are too long will result in a circular curl.

What You'll Learn
Clinch nails should be longer than the wood being joined
Clinch nails, or clenching, is a technique used to join two pieces of wood together. It involves driving a nail through both thicknesses of wood, leaving about a 1/4" of the nail sticking out, which is then bent and driven back into the wood. This method of nailing adds remarkable strength to a joint, increasing the holding power of a nail by up to 464%, depending on factors such as the type of wood and its moisture content.
When clinching nails, it is important to use nails that are longer than the wood being joined. This is because the nail needs to pass through both thicknesses of wood and have enough length left over to be bent and driven back into the wood. If the nails are too short, clinching is not possible. On the other hand, if the nails are too long, they will form a circular curl, which is also not ideal. Therefore, the nail length needs to be just right to achieve a strong 180-degree turn and a secure clinch.
The process of clinching nails can be done by hand or with machines. When using a hand clincher, one common technique is to drive the nail through the work and rest a steel plate, anvil, or a second heavy hammerhead on the nail's head. The tip of the nail is then tapped with a hammer, causing it to curl over. The drooping tip is then driven back into the wood. Another technique is similar to the machine process, where the nail is driven through the work and against a "bucking iron," which curls the tip and forces it back into the wood.
When working with softer woods, such as spruce, it is recommended to use nails that are at least 2 cm longer than the thickness of the wood. This ensures that the nails can be countersunk, and any nail holes can be easily filled or hidden with paint. Additionally, when clinching nails, it is important to consider the placement and layout of the nails for optimal strength and aesthetics.
In conclusion, when clinching nails, it is crucial to use nails that are longer than the wood being joined. This ensures that the nails can pass through the wood and have enough length to be bent and driven back in, creating a strong and secure joint. By following this principle and choosing the appropriate nail length, woodworkers can take advantage of the increased holding power and durability that clinching provides.

The nail tip should stick out 1/4
Clinch nails are used to fasten two pieces of wood together. The process of clinching nails involves driving a nail through both thicknesses of wood, leaving about 1/4" of the nail tip exposed. This remaining tip is then bent over and driven into the wood, creating a strong joint.
The length of the nail used for clinching is crucial. If the nail is too short, clinching is not possible. Nails that are too long will result in a circular curl when bent over. The ideal length allows the nail tip to turn 180 degrees and clinch securely. To achieve this, the nail should be slightly longer than the combined thickness of the wood pieces being joined.
When clinching nails, it is essential to consider the direction in which the nail will bend. One method involves driving the nail against a steel plate, causing it to curl and be driven back into the wood. This technique can be challenging to control. Another approach is to use a hand clincher or a bucking iron to curl the nail tip and force it back into the wood.
Clinch nails provide remarkable strength to joints. They are quick to execute, require no glue, and allow for wood expansion and contraction. Clinching nails can increase the holding power of a nail by 45% to 464%, depending on factors such as wood species and moisture content. Additionally, bending the tip across the grain can further enhance the holding power by 20%.
Clinch nails have been used in various applications, including building utilitarian boxes, picket fences, and boats. They are valued for their durability and ability to withstand wet and dry cycles, making them ideal for outdoor structures.

Clinch nails don't require glue
Clinch nails are an effective and durable fastening method, offering remarkable strength without the need for glue. The process of clinching involves driving a nail through two pieces of wood, leaving around a quarter of an inch of the nail exposed. This protruding tip is then bent and driven back into the wood, creating a strong joint.
The length of clinch nails is crucial to achieving a secure hold. Nails that are too short will not provide enough material to clinch, while excessively long nails will result in a circular curl rather than the desired 180-degree turn. The ideal length for a clinch nail is slightly longer than the combined thickness of the wood being joined, allowing for a strong clinch that holds the wood firmly together.
The versatility of clinch nails is evident in their ability to accommodate different types of wood and moisture content. A 1948 study by the U.S. Forest Products Laboratory found that clinching increased nail holding power by 45% to 464%, with a 20% improvement when bending the tip across the grain. This adaptability makes clinch nails a reliable choice for various projects, ensuring a strong hold regardless of the specific wood characteristics.
Clinch nails offer several advantages over other fastening methods. Firstly, they do not require glue, eliminating the need for drying time and simplifying the overall process. Secondly, clinch nails provide remarkable strength, as evidenced by personal testimonies and the aforementioned study. This added strength is particularly beneficial for projects that undergo stress or expansion and contraction, such as gates, fences, or boat construction.
The technique for clinching nails can vary, but it typically involves using a hammer or a clinching iron to bend the nail tip back into the wood. The process may include driving the nail against a steel plate, anvil, or bucking iron, causing the tip to curl and secure the joint. While clinching nails may take some practice to perfect, it is a valuable skill that adds durability and strength to woodworking projects, ensuring a tight and long-lasting hold.

Use a steel plate to bend the nail
Clinch nails should be long enough to pass through both thicknesses of wood being fastened, with about a 1/4" of the nail's tip sticking out to be bent over and driven into the wood.
Using a Steel Plate to Bend the Nail
Using a steel plate to bend a nail is a common technique in clinching. This method involves driving the nail through the workpiece and resting a steel plate, anvil, or a second heavy hammerhead on the nail's head. Then, the tip of the nail is tapped with a hammer, causing it to curl over. Finally, the drooping tip is driven back into the wood.
- Drive the nail through the workpiece until it just pokes through the other side.
- Place a steel plate behind the nail head.
- Tap the tip of the nail with a hammer to curl it over.
- Remove the steel plate.
- Hammer the nail flat against the wood, bending it in the direction you want the clinching to go.
- Drive the nail fully through the wood.
- Hammer the nail over into the wood, either along or across the grain, depending on your preference.
This technique can also be done using a pneumatic nail gun, where the nail is fired into the wood at an angle and a steel plate is placed behind the nail to catch the tip and bend it into the wood.
While this method is effective, it may take some practice to control the direction of the bend. Additionally, the use of a cast iron table saw wing can provide a large area to support your work and facilitate the clinching process.

Drill pilot holes for furniture
Clinch nails are used to fasten two thicknesses of wood together. The nail is driven through both pieces of wood, leaving about a 1/4-inch tip that sticks out and is then bent and driven back into the wood. This method of nailing adds strength to the joint.
When creating furniture, it is often necessary to drill pilot holes for nails and screws. Pilot holes can prevent the wood from cracking, splitting, or blowing out. They can also help to reduce the risk of screws breaking from force and can keep the screw head from stripping. Pilot holes also make it easier to drill in the screw and can help ensure that the screw enters the wood in the precise location that you want.
To drill pilot holes for furniture, follow these steps:
- Choose the appropriate drill bit for your material and fasteners. For screws, select a bit that matches the inner diameter of the threaded part, not the diameter of the threads. For nails, use a bit that is slightly smaller in diameter than the shank.
- Know the chuck size of your drill and purchase bits with the correct shank size.
- Mark the location where the fastener will go. Measure across the workpiece from one edge to the other and from one end to the other, making short lines at the intersection point. This intersection is the center point for the pilot hole.
- Place the bit fully seated in the chuck and tighten it completely, ensuring the bit is centered.
- Turn the drill/driver’s setting to drill (look for an icon that looks like a drill bit).
- Drill the hole to a depth that is appropriate for your fastener. For nails, the pilot hole should be significantly smaller in diameter than the nail, so there is a tight fit. For screws, the pilot hole size should be approximately the same diameter as the screw’s shank minus the threads.
Pilot holes are not always necessary, especially for softwoods like spruce or pine. However, they can save time and money by reducing the risk of damage to your materials.
