The Diamond self-tapping screw features a sharp needle-shaped tip with an 18-degree angle. Three diamond-shaped wings are positioned around the screw tip for precise cutting action. These wings create micro-cuts that guide the first thread pitch into the material. The threads are designed with a step-like pattern and variable pitch ranging from 1.5 to 2.2 millimeters. The first pitch enables easy penetration into metal sheets with 0.5 to 1.5 millimeters thickness. The second pitch with deeper profile ensures secure engagement within the metal substrate. The thread angle measures 35 degrees with sharp cutting edges for efficient material displacement. This unique geometry reduces the driving force into metal by up to 40 percent. The threaded section covers at least 65 percent of the total shank length.

The Diamond self-tapping screw is manufactured from 10B21 alloy steel with 0.18 to 0.23 percent carbon content. Surface carburizing heat treatment produces a hardness range of 550 to 700 Vickers. The case hardening depth measures between 0.1 to 0.25 millimeters from the outer surface. A three-layer zinc, nickel, and chromium coating system with total thickness of 12 microns is applied. The inner zinc layer with 5 microns thickness ensures adhesion to the steel substrate. The middle nickel layer at 4 microns enhances corrosion resistance performance. The outer hard chromium layer at 3 microns provides surface brightness and wear resistance. The driving torque for these screws ranges from 3.5 to 6 Newton meters. Applications include galvanized sheets, aluminum panels, and reinforced plastic components.You can order and buy -پیچ خودکار دیاموند from Iran by contacting us through whatsaap and email.
