The formula to calculate the screw length is:
\[ SL = MT + PD \]
Where:
Screw length is the total length of a screw that is required to fasten two materials together. It includes the thickness of the material being fastened and the depth the screw must penetrate into the second material to achieve a secure fit. The correct screw length is crucial for the integrity of the connection and to ensure that the screw does not protrude unnecessarily or fail to provide sufficient grip.
Let's assume the following values:
Using the formula to calculate the screw length:
\[ SL = 10 + 5 = 15 \text{ mm} \]
The screw length is 15 mm.
