What is the difference between Torx and Star Bits? The term Torx stands for the trademark name, while the term “star” describes the tool generically. The two can be used interchangeably, since the tools are identical. The Star Plus design was introduced to make a better Torx Bit, and Torx Plus screws cannot be used with the old Star Bits. The classic Star Bit can be used on the newer design, but it will be loose.
