I own commercial buildings. Inevitably, you get sucked into doing repairs to a lot of stuff.

I think the best answer to your first question is just to post a catalog of video links. Look at how many jobs start with a torx driver.

Sure, there's plenty of torx fasteners on the newer cars, but I dont recall ever seeing tamperproof or security ones. I mean, you could certainly USE a security driver to remove them.

I thought that the majority of restroom fasteners were shear bolts. Go figure.

Shear bolts would make no sense. Anyway, no. The first time I discovered the tamper proof screws in the restroom dividers, I had to use the tamper bit from the Hazet "Porsche" tools that I happened to buy and store in the trunk of my Cayman. It's strange, I know.....

I'm just asking if Porsche is now using security torx on this stuff. most of the time, the trim screws and whatnot are T25. Was wondering if i have to go buy a new set of security bits for this stuff.

Coincidentally, removing these and others is why I want a good cordless driver.

I was looking recently at Torx bit sets. It's harder to NOT find a set of tamper proof bits now.

On the posted videos above I noticed the techs using a cordless tool to remove and install the under belly pans. I understand that it saves time and they are handy for a speedy oil change but it is one of the reasons I hate taking my car to a dealership (and most indys).

When I purchased my 2013 CPO BMW 128i, it had a history of dealership service for all regular maintenance items. For its first oil change under my care I removed the plastic under belly pan (15 fasteners) to get to the drain plug - more than half of the plastic female inserts for the screws were stripped. The techs just hurriedly drive in the fasteners without thinking of the proper torque.

Was glad I had a set of e-torx in the box.

I know what the issue was, HD has "impact driver" and "impact wrench". I'd looked up drivers, which use the 1/4" hex vs square wrench. When I look up impact wrench, I find what I was expecting.

I think I'm going to go with the current iteration of the kit above. 18V 1/2" drive wrench, charger, 4ah battery kit and then a similar kit for the leaf blower, that way I'll have two 4ah batteries. Then I'm going to go with an electric, corded pressure washer. I think that'll be more effective than a battery powered model, especially since those are 40V which would mean buying stuff to support the 40V gear, probably to only have a single 40V item.

^ Yup. That's what I was clumsily trying to describe in Post #81. The impact driver is what you use for the torx tamperproof thingies. It's important to go slowly at first so you don't rip the threads right off, and then you just bump the trigger rather than go full squeeze.

Thought I'd circle back and show the impacts that I bought because of this thread. I'm going to try them out. I also have a 3/4" Makita corded impact wrench not shown here.

The 1/2" has a very nice feature, a wheel adjustment for speed/ torque so you don't overdrive the tool.

The 3/8" wrench has a 5.0 Ah battery, but the 1/2" has a 4. Go figure that one. Both batteries charge in about 20 mins. Impact sockets are by Snap-On and Wright Tool.
