Just joking around. Sort of. I really appreciate the simplicity and quality of the Stihl design. As you know, you can completely strip and overhaul a Stihl with T27, 8mm hex, flat screw driver and a scrench for bar nuts and spark plug. Simple is as simple does...
These could be used: http://www.mcmaster.com/#90074a106/=vjhccn At nearly a dollar/each that's not cheap. But so could a set of metric high-collar lock washers. Or Loc-tite. Did anyone mention Loc-tite yet? David
Husqvarna would do well to "borrow" Stihls whiz-lok style fasteners. (And their muffler-stud design from the clamshells....) I like the Torx drive better than a hex but hey, they want to keep the hex, I'm cool with that. Hell, it ain't like Stihl hasn't taken a few pages from the Husq. Playbook lately.....
That can be applied from everything from pick up trucks to boats to snowmobiles. All major manufactures have at least 1 cool/ handy feature that nobody else has.
They use a lot of screws n bolts serrated on the underside in the manufacture of cars, I screwed down about 10 million of them
A little trick for red loctite on small fasteners. Touch a hot solder iron to the top of the screw for a minute or so. The locking compound thermally degrades at 400F or so. They come right out.
Well this may sound a bit strange to most of you but here goes. On occasion I have several friends that bring fire arms to me to work on. If some of their problems are caused be screws getting loose like on a scope mount or a lever action loading ramp getting loose, I use plain old finger nail polish. Clean the fastener VERY good and apply a small amount to the threads and install. It holds really well and when the part does have to be taken apart again for service and or cleaning it is much more forgiving than a lock tite type product. And no, I don't use FN polish and neither do my wife but I keep a bottle around makin screws stay put.
