Roof tile screw "Long screw"

Prevents head flying and bending! Solves the problems of long screws!

The "Long Screw" is a roofing tile screw that prevents head snapping and screw bending. In recent years, the diversification of residential design has led to an increased demand for long screws. However, as the overall length increases, strong loads are applied during fastening, raising concerns about head snapping and screw bending, which can reduce fastening capability. Our product prevents head snapping and screw bending by applying a knurling process to the body of the screw, which allows for expected cold working hardening (the material heats up and hardens due to instantaneous pressure applied to the solid). 【Features】 - The knurling process on the body prevents head snapping and screw bending. - The split end processing at the tip improves grip and enhances workability. - The undercut below the neck ensures tight contact with the sealing packing, preventing water leakage. - Split end processing can be applied to long screws up to 115 millimeters. *For more details, please refer to the PDF document or feel free to contact us.
