Self-tapping screws for panels

Self-tapping screws for panels are special fasteners for mounting multilayer facing-and-structural panels to a metal frame.

This type of self-tapping screw has a complex design and exceeds other fastener models in length.

The shank is divided into 4 sections. Near the head there is a wide-pitch thread — it allows the screw to enter the facing layer of the sandwich panel freely. Next comes a smooth section equal in length to the thickness of the panel. This is followed by a fine thread with a chip-removal groove, adjoining the drill point.

The head is hexagonal, with a flat washer located beneath it. The washer provides tight clamping of the fastener to the panel without denting the surface, dampens vibration loads and ensures a tight seal of the joint.

Self-tapping screws for panels are made of high-strength steel with corrosion protection. FLOK supplies the full range of sizes and versions of this fastener with delivery across Russia.
