Countersink Depth Calculator

This calculator computes the required countersink depth based on the screw diameter and head angle.

1. Enter Screw Diameter: Enter the diameter of the screw.
2. Select Head Angle: Choose the angle of the screw head (e.g., 60°, 82°, 90°, 100°, 120°).
3. Calculate: Click the "Calculate" button to compute the countersink depth.
4. View Result: The calculated countersink depth will be displayed.

A countersink is a conical hole cut into a manufactured object, often used to allow the head of a countersunk screw, bolt, or rivet to sit flush with or below the surface of the surrounding material. This calculator helps determine the precise depth required for the countersink, ensuring a perfect fit for your fasteners.

The countersink depth is calculated using basic trigonometry. The formula takes into account the diameter of the screw and the angle of the screw head. By dividing the screw diameter by two and then dividing that result by the tangent of half the head angle, we can determine the depth at which the screw head will sit perfectly flush with the surface.

The calculator provides the 'Countersink Depth', which represents the precise depth you need to drill the conical hole. This ensures that when you insert the screw, its head will sit perfectly flush with the surface of the material. A correct countersink depth is critical for both the aesthetics and the structural integrity of the finished product.

This calculator is essential for anyone involved in woodworking, metalworking, or any other manufacturing process that involves using countersunk screws. Whether you're a professional craftsman or a DIY enthusiast, ensuring the correct countersink depth is crucial for achieving a professional finish and maintaining the structural integrity of your project. This tool eliminates the guesswork, providing accurate results and saving you time and potential errors.

Disclaimer: Always double-check your calculations and consider the specific materials and screws you are using. This calculator provides a theoretical depth, and practical adjustments may be necessary based on your specific application.
