### Torx® Fasteners

Torx® fasteners have a star shaped head of either an internal or an external design.

These fasteners come in three different types. The most common being internal, these fasteners require a star shaped driver and are frequently found on headlight retainers and adjusters. The second type is external, these fasteners require a star shaped socket and may be found in odd locations such as the wheel cylinder retaining bolts. The third type is tamper resistant, which are used in places that manufacturer's are very serious about avoiding a Do-It-Yourselfer (DIYer) from touching. These look similar to the internal type however, they have a pin in the center of the fastener preventing the use of the standard Torx® driver. They may be found on components that are meant to be serviced only by authorized repair centers.
