● Patented: Taiwan, Japan, Europe


KTX-Convex Head

● Special convex head with balanced force transfer

l       ● No hex corner, no wear out

l       ● Customized nut setter, no cam-out

l       ● Higher torque transfer

● Longer nut setter lifespan



Easy installation

● The front ball point helps to direct the whole screw drilling into concrete vertically

● Cambered high threads increase the loading capacity and decrease the splinter of concrete. When vibration, dynamic loads, settlement and relaxation, it will keep the fixed tension

● Different head types available, tamper-resistant with KTX-Convex Head

● Reusable



● Double low threads and the point easily control the screwing directions and minimize the friction during installation

● Force-saving during installation, high pull-out value, avoid driving obliquely


Material control 

● Grade 10.9 steel and Grade 10.9 high tensile stainless steel available

● Innovative stainless steel material provides higher strength and long life corrosion resistance with adequate toughness


CE Marking

● Cooperation of ETA application or authorization



● Patented: Taiwan, Japan, USA, Europe
