Details

Application

These self drilling screws are designed to securely attach a variety of GTEC plasterboards to metal studs exceeding 0.7mm thickness.

Correct screw placement—at least 10mm from bound edges, 13mm from cut plasterboard edges, and a minimum 3mm from stud edges—ensures structural integrity. The screw must penetrate at least 10mm into the metal stud for a firm hold.
