The video “What is a Confirmat Screw – When & Why to use them” is by Jeff from Today’s Craftsman. Jeff explains confirmat screws, highlighting their unique properties and applications, especially for melamine and plywood.
What is a Confirmat Screw?
A confirmat screw is designed specifically for joining melamine or particle board, making it an essential tool for assembling flat-pack furniture. Jeff points out its resemblance to a dowel, showcasing its robust 5mm shank and wide threads that provide exceptional holding power. This makes it particularly effective for butt joints, which are common in cabinet construction.
Why Use Confirmat Screws?
One of the standout features of confirmat screws is their strength. They offer a much sturdier connection than traditional wood screws, especially in melamine. Jeff explains that while confirmat screws may be associated with less expensive furniture, their effectiveness cannot be overlooked. He notes that while traditional screws can sometimes fail in these materials, confirmat screws excel.
Specifications and Tools Needed
For those interested in using confirmat screws, Jeff provides some specifications. A typical confirmat screw is about 50mm long (approximately 2 inches) with a 5mm shank and 6.8mm threads. To work with these screws, you will need a specific drill bit designed for confirmat screws, which includes a counter sink for the head. Jeff uses a “Make It Snappy” bit that accommodates the screw’s dimensions perfectly.
Installation Process
During the installation, Jeff emphasizes the importance of proper alignment. He suggests using biscuits for alignment along with clamps to keep everything steady. This ensures that the holes drilled for the confirmat screws are aligned accurately, which is crucial for a strong joint. He demonstrates how to drill the holes with a Brad Point bit, emphasizing the necessity to clear chips to maintain precision.
Strength Test: Confirmat vs. Traditional Screws
To showcase the strength of confirmat screws, Jeff conducts a live test. He compares a joint made with confirmat screws to one made with standard wood screws. The results are striking. The traditional wood screws fail under stress, breaking off easily, while the confirmat screws hold strong, demonstrating their superior shear strength.
Performance in Different Materials
Jeff notes that while confirmat screws perform exceptionally well in melamine, they may not hold quite as strongly in plywood. However, they still outperform traditional screws, making them a reliable choice for various woodworking projects. He encourages viewers to consider using confirmat screws for their next project, especially when working with melamine.
Final Thoughts
In conclusion, Jeff’s exploration of confirmat screws highlights their unique benefits for woodworking, especially for melamine and plywood projects. Their strength and ease of use make them an invaluable addition to any woodworker’s toolkit. For anyone looking to enhance their furniture assembly skills, trying out confirmat screws is certainly worth a shot!
