Cylindrical Head Inner Hexagon Self Drilling Screw

This Cylindrical Head Inner Hexagon Self Drilling Screw features a specification of ST4.2-18*32 and is manufactured from SUS410 stainless steel, with a single weight of 2.27g. The SUS410 material undergoes heat treatment to achieve high hardness, enabling the drill point to penetrate metal substrates rapidly for simultaneous drilling and tapping. The cylindrical head with an inner hexagon drive allows for the application of high tightening torque, making it suitable for installations with limited space. The surface is treated with brightening to improve smoothness and corrosion resistance. This fastener is widely used in curtain walls, metal furring, and mechanical equipment installation, eliminating the need for pre-drilling and enhancing assembly efficiency.
