167552-29TS- Penta-Star Key Wrench Set

There has been a lot of confusion over the naming conventions of these two screwdriver head types, so hopefully this article helps clear things up! Torx is the trademark name for these screwdriver bits, while star refers to their generic classification. While they can be used interchangeably, it is important to note that “Star Plus” is an improvement on the design of the star bit and is not compatible with old screws. The classic star bit can be used in place of Star Plus bits and some bolts — but it will only be a loose fit.

Star Plus Drive is a revolutionary drive system used in a range of industrial equipment that delivers optimized transmission of torque to the fastener. With its unique 0-degree angle drive, which is vastly different from conventional systems that have a 15-degree or 20-degree angle, the Star Plus Drive virtually eliminates radial forces that cause fastener recesses to stretch and stress. This innovative system has made a significant impact on assembly lines, improving performance and increasing efficiency.
