Countersink Depth Calculator
Result
Countersink Depth Calculator Calculate the countersink hole depth needed for a flat-head screw based on head angle and diameter. — free online calculator.
Formula
- Countersink Depth Calculator calculates its result from Screw Head Diameter, Shank Diameter, Head Angle. It uses the formula Depth = (head diam − shank diam) / 2 / tan(half angle). Change any input to recalculate the result instantly.
- The main inputs are Screw Head Diameter, Shank Diameter, Head Angle. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Countersink Depth
- Screw Head Diameter: 0.375
- Shank Diameter: 0.164
- Head Angle: 82
Using Screw Head Diameter = 0.375, Shank Diameter = 0.164, Head Angle = 82, the calculated result is 0.3198652319.
