TORX® 6-Lobe Recess, TX and ISR Recess have become extremely popular because of the significant advantages they provide in assembly. TORX® 6-Lobe Recess, TX and ISR Recess Alternative Drive Systems facilitate quick and positive location and engagement of the driver into the recess. The shape and increased contact surface between the driver and screw allows for secure and increased torque transmission during installation and removal of the screws.
The design and function of this drive system eliminates cam out, a condition common during installation or removal of Phillips® or cross recessed screws. Cam out occurs during installation or removal of Phillips® Drive screws when the driver rises in the recess, causing movement of material in the recess and resulting in a deformed recess or cone shaped hole.
TORX® 6-Lobe Recess, TX and ISR Recess Alternative drives are available in many styles of fasteners. The most frequently requested styles are Pan Head and Flat Head Torx® Machine Screws and Button Head Torx® Machine Screws. Torx® Drive Thread Forming Screws for use in metal and plastics are gaining in popularity due the desirable drive characteristics. Recently the I.S.O., International Standards Organization, has adopted and published the TX Drive, TORX® 6-Lobe Recess, TX and ISR Recess Alternative as a viable alternative to Licensed Torx®, resulting in a tremendous increase in the number of manufacturers that can now offer competitively priced products.
