Cylindrical screw with imprint TX DIN-912 ISO-14579

Cylindrical screw with Torx TX recess DIN 912 = ISO 14579

Torx head screws have better tightening than other Allen, Phillips or heads with flat slots.
  Due to their design, they have a higher torque than the rest of the heads, minimizing or eliminating the risk that we have in the other heads of damaging them, even to the tools.

Its design also adds greater security for possible manipulation since the tightening tools are more exclusive, in addition to being able to have variants that make them almost tamper-proof in practice.

Stainless steel grades A, A-2, A-4 and others upon request.
