5. Self-drilling and tapping screws are usually described by screw diameter series, screw number per inch length and screw length. There are 10 and 12 screw diameter series, the corresponding screw diameter is 4.87mm and 5.43mm respectively; There are 14, 16 and 24 threads per inch. The more threads per inch, the better the self-drilling capability.
The main uses of stud are:
1, in the main body of large equipment, need to install the accessories, such as sight glasses, mechanical seal, deceleration machine frame, etc., this is just use the stud, end turned into the main body, the other end with nut after installed accessories, because the attachment is often removed, thread will wear or damage, use the stud replacement will be very convenient.
