Product Feature

Convenient slot design: The standard cross slot (PH2) perfectly fits the head of the standard electric screwdriver, effectively transmitting torque even under high torque, greatly reducing the probability of slipping and protecting both the screw and the tool.

Concealed and aesthetically pleasing: The black surface is similar to the base color of most gypsum boards, which can maintain visual cleanliness and unity, thereby reducing interference with the decorative effect.

Cost advantage: Carbon steel material provides excellent rust prevention performance while also having better cost advantages, making it an ideal choice for large-scale projects.
