Torx CSK Self Tapping Screw SS-304

Product Description

The hexalobular socket screw drive, known as Torx or star drive, uses a star-shaped recess in the fastener with six rounded points. It was designed to permit increased torque transfer from the driver to the bit compared to other drive systems. This system features a 15-degree drive angle which provides high torque transfer. Radial forces are drastically reduced resulting in longer tool life. It has vertical sidewalls which increases tool engagement CAMOUT is defined as the force upward on a screwdriver as the torsional force is increased to tighten the screw. Torx Screws do not have cam out problems as no cam out forces are created to push the driver up and out of the fastener recess. Due to this, the pressure required to keep the screw driver in the socket reduces significantly and therefore reduces operator muscular stress and fatigue.

Because of these advantages, Torx drive screws are very popular in the automotive and electronics industries.

The countersunk head facilitates flush fixing.
