What is ... the clamp thickness? h1>
What is clamp thickness and how is it calculated for self-drilling screws?In short, the clamp thickness is the area of a self-drilling screw which can be used to connect two components. It is thus the area of a screw which can absorb and carry load.
How is the clamp thickness calculated?If you approach the subject a little bit unsuspiciously, you could come to the conclusion that the clamping thickness of a self-drilling screw is quite easy to determine from the length of the screw. Hence, the clamp thickness is the threaded part of a screw minus the length of the drill point, right?
Wrong! Especially with regard to the clamp thickness of self-drilling screws, there are some important points to note:
