Fields of application

They are made of high quality and high strength carbon steel C1022, thus they are ideal for fastening hardware directly on PVC.

The countersunk head is slightly radiused. Three finishes are available in the catalogue: zinc Cr3 8µm (with salt spray resistance of 120 hr), zinc Cr3 3µm (with salt spray resistance of 24 hr) and, on request, zinc Cr3 8µm (with salt spray resistance of 400 hr).

Laying and fixing operations

Fixing and tightening the full thread TSPG PH PVC screws is extremely easy, thanks to the diameter and the shape of the head, which allow the alignment on hardware countersink, also in case of irregular screwing.

An electric screwdriver with a PH2 tip (bit is not included in the package) is required. The PH recess is deeper than the standard one, allowing a greater and more effective tightening torque.

The screw is threaded up to the tip , for faster tightening and easier grip on PVC.
