Hex Flange Self Drilling Screw is a widely used fastener, and has the advantages of high strength, single-body, single-side assembly connection, disassembly and reuse, etc. With the development of world industrial technology and social progress, Hex Flange Self Drilling Screw is bound to have greater development and wider use.
Hex Flange Self Drilling Screw screw-in test: screw the self-tapping self-drilling screw into a steel plate with a reserved test hole, the Hex Flange Self Drilling Screw should form a matching thread in the test plate, and the thread of the screw itself No deformation or damage occurs until the end taper thread completely passes the test plate. The screw-in test is only applicable to AB, B, BP and other types of self-tapping and self-drilling screws.
The Hex Flange Self Drilling Screw is mostly used for connecting thin metal sheets. The thread is an ordinary thread with an arc-shaped triangular section, and the thread surface also has high hardness, so when connecting, the screw can also tap the inner thread in the threaded bottom hole of the connected piece to form a connection.
