Step 91 6-Lobe Screw Drives

[[br]]After the expiration of the Torx® design patent in 1988, many non-licensed fastener manufacturers started producing screws with what has become known as the 6-Lobe recess. Today only those companies who are licensed by CAMCAR-Textron can market this design as a Torx® Recess because even though the patent has expired the trademark is still active. Those who are not licensed by CAMCAR-Textron but use the Torx® name are in violation of international trademark laws.
