The flat head self tapping screw is a self threading fastener that installs without pre threading or a nut. Screw diameter typically ranges from 2.2 to 6.3 mm, with lengths from 9 to 75 mm. The flat head is designed at an 82 to 90 degree angle and sits flush with the surface after installation. It is made from hardened carbon steel or stainless steel with surface hardness of 450 to 700 HV. Galvanized or phosphate coating improves corrosion and wear resistance. Sharp precision threads enable fast penetration into thin metal, plastic, and wood.
Structurally, the screw features a drill point or sharp tip for thread formation during installation. Standard thread pitch ensures uniform stress distribution and higher joint strength. Shear load capacity up to 800 N and high tensile resistance provide reliable mechanical performance. The flat head design distributes pressure evenly and reduces surface stress concentration. This screw is widely used in electronics, metal equipment, automotive industries, and light structures.You can order and buy Window Screw from Iran by contacting us through whatsaap and email.

Material of Flat Head Self-Tapping Screws in iran
Flat head self-tapping screws are typically made from carbon steel or alloy steel with high surface hardness to ensure adequate shear and tensile strength. For industrial or corrosion-resistant applications, zinc, nickel, or galvanized coatings are applied. Stainless steel screws A2 or A4 are used in humid or acidic environments for high oxidation and rust resistance. Heat treatment and tip hardening improve penetration ability and screw performance in the base metal. Selecting the appropriate material based on substrate type and applied load ensures connection safety and screw service life.
