Sk Professional Tools Socket Bit, Insert Length 11/16", Replaceable Insert Yes, Torx, Tip Size T20

These Torx Plus socket bits have one end that fits a Torx Plus indentation in the fastener head. These bits are less likely to cam out, where the Torx bit slips out of the indentation on the fastener head once the torque required to turn the fastener exceeds a certain amount. They allow Torx Plus fasteners to be tightened to a higher torque compared to standard Torx fasteners.
