Product Description
Product Overview
This product is a hexagon head with washer cross recessed self-tapping screw, manufactured from carbon steel and subjected to zinc plated surface treatment. It integrates a hexagon head, an integral flat washer and cross recessed self-tapping threads into one. The hexagon head design facilitates applying high torque with a wrench, the washer can increase the bearing area and protect the workpiece surface, the cross recess is compatible with common screwdrivers, and the self-tapping threads can form a reliable connection on thin plates and other materials without pre-drilling.
Core Advantages
-
Multifunctional Integrated Design: Integrates hexagon head high-torque installation, washer anti-loosening protection, cross recess convenient driving and self-tapping function into one, simplifying inventory and assembly.
-
Convenient and Efficient Installation: The self-tapping thread design reduces the pre-drilling process, and the cross recess and hexagon head provide flexible selection of installation tools.
-
Reliable and Anti-Loosening Connection: The integral washer disperses the pressing force, protects the workpiece surface, and helps prevent connection loosening.
-
Corrosion Protection: The zinc plated layer provides effective rust and corrosion protection for the carbon steel base material.
