These roles of Hex Flange Self Drilling Screw products



Hex Flange Self Drilling Screw products are mostly used for joining between thin metal sheets. Its thread is an ordinary thread with an arc-shaped triangular section, and the thread surface also has a high hardness. Therefore, when connecting, the screw can also tap an internal thread in the threaded bottom hole of the connected piece to form a connection. This kind of screw is characterized by small tightening torque and high locking performance. It has better working performance than ordinary self-tapping screws and can be used instead of machine screws.

Self-tapping screws for wallboard are used for the connection between gypsum wallboard and metal joists. Its thread is a double-ended thread, and the thread surface also has a high hardness (≥HRC53), which can be quickly screwed into the keel without drilling a prefabricated hole to form a connection.

The difference between Hex Flange Self Drilling Screw products and ordinary self-tapping screws is that when connecting ordinary self-tapping screws, two processes are required: drilling (drilling threaded bottom holes) and tapping (including fastening connections); self-drilling and self-tapping In screw connection, the two processes of drilling and tapping are combined at one time. It first drills holes with the drill bit in front of the screw, and then taps the screw (including the fastening connection), which saves the construction time and improves the construction efficiency.
