Product Information

The fasteners involved have heads that are hardened and tempered to withstand the driving torque without destroying the star points. They're known by the Americans as "Triple Square" or VAG as ZXN and are used as they can handle higher torque before camming out. The issue with the Halfords type is that they are not an impact bit the the star bit is inset into a socket which makes is very weak. German vehicles like Volkswagen, Porsche, Mercedes, BMW, and Audi in particular all use triple Square.

The design is similar to that of the double-square—in both cases, the idea being that it resembles a square (Robertson) but can be engaged at more frequent angles by the driver bit. For automotive needs, that means things like drive train components and cylinder head bolts which can be tougher to remove than other components.The hex bolt I wasn't too worried about since it is not a stretch bolt and some loctite will work just fine. I am about to do this same job - waiting on parts and triple-square bits to be shipped - and this will make me a lot more prepared. German manufacturers Audi, Mercedes, BMW, Volkswagen, and Porsche all favor the triple square design. Another major reason that Torx screws are so popular is that they allow for a higher torque transmission than most other screws. Despite the similar naming scheme to metric fasteners, there is no correlation between the name of the size and the dimensions of the tool.

The reason for the implementation of triple square bits is due to the high torque applications that vehicles can require. Some users have ran into trouble when their automatic chargers switched off once it thought full charge was reached.

Initially, Torx screws were highly tamper-resistant because there were not screwdrivers or drive systems widely available. The 12-pointed internal star shape superficially resembles the "double hex" fastener head, but differs subtly in that the points are shaped to an internal angle of 90° (derived from a square), rather than the 120° internal angle of a hexagon. Recommend you use a breaker bar that has as little play as possible and "soak" the bolts with some sort of penetrating oil for about 10-15 mins before you start trying to loosen them.

If you have a German vehicle and plan to do your own work, pick up a set of triple square bits first because they will come in handy at some point. Though there are other vehicles that make use of the triple square head, most European vehicles feature them prominently. Some cheap bits will not fit well and with any spline type tool it is vital to completely clean out the splines in the bolt head.Triple square fasteners are commonly found on German vehicles such as Audi, BMW, Mercedes, Porsche, and Volkswagen. And for that reason, Torx is the superior choice for just about any application that requires a little bit of extra force and torque. Triple-square drive fasteners have been used in high-torque applications, such as cylinder head bolts and drive train components. They are built to hold up against repeated use in those high-torque situations, meaning that a set of bits will last a good, long time. They are commonly found on German vehicles such as BMW, Opel, Mercedes, Porsche and those from the Volkswagen Group ( Audi, Seat, Skoda, and Volkswagen).

This is as good a time as any to admit that the one time I replaced the rear brake pads I didn't do anything to the rotors - just left them on there.When it comes to drive train components and cylinder head bolts, the triple square bit offers a higher allowable torque to remove even the toughest or most seized components. The simple fact of the matter, however, is that there are so many different options that it can become confusing. Because of the improved fit and its ability to take on larger torque capacity, Torx bits tend to make removal easier. While it is important that the bit be able to stand up to the extra torque, it is not the only important component.
