Polydrive, also known as RIBE or RIBE CV, is a fastener specification. It is used primarily in the automotive industry.
A polydrive bit has 6 teeth at equal spacing and with flat tips to the teeth. Size is determined by diameter at the star points.
Functionally, it is similar to torx and spline drive, all of which are systems using internal bit-socket drivers along with specially-designed bolts, screws, and other fasteners. Its primary advantage over older fastener driver standards, such as the common Phillips head (and its sibling Pozidriv), is that it resists cam-out, and is thus used in higher-torque applications such as brakes and driveshafts..
