Are newer Huskies still assembled with 4mm allen cap screws?

    I have a 6"-long T27 torx bit that I use with a rechargeable drill for working on Stihl saws, which is great because almost every fastener on Stihls use that size and type of driver. I'd like to procure a equivalent bit for working on Husqvarnas. My experience so far says that means I need a 4mm bit, but I haven't worked on any Huskies newer than the 359. Are they still built with the same sort of fasteners? The only source I've found for such a bit sells them in packs of 10 and ships direct from China, so I'm hoping they'll be useful on a lot of different models.

    Just buy a regular allen wrench and cut the short leg off. Instant drill bit.

    Yeah, that's an option but I'd rather have the purpose-made driver. I already have one metric set, and buying another would cost about as much as 10 driver bits anyhow.

    If you find a cheap source? Can you post a link? They use 2 different sizes. But the 4 mm is the most popular. I believe 3 mm is the other one. To take off many of the mufflers, the muffler bolts are one size and the muffler bracket is a smaller size. (Either 4 mm and 5 mm or 4 mm and 3 mm).

    To lazy to go outside and look. Eating dinner, getting a strange look from the wife o_O (I was just thinking really hard in which two it was, and she seen smoke coming from my ears ;)) :confused:

    I'm partial to a set of good t-handles. Less risk of stripped screws, cross threading and breaking cases by grabbing the wrong screw and over driving it:whistle:

    4 and 5 are the sizes. 3/16" on cylinder bolts on 288 and 394/5 if I remember right.

    I've dealt with that by using very low torque settings on my little 9.6v rechargeable.

    The first source I found was through a sketchy-looking site, but then I found the exact same item sold through Amazon by a third-party seller for about the same price. I was only looking for 4mm drivers. The 100mm length is a little over $10 for 10 pieces, and the 150mm length is just under $15 for 10 pieces. I was thinking of buying a batch and putting the extras up in the classifieds here.

    This is why I don't like using cordless drills as powered screwdrivers. Waaaaay too much power available, heavy, and just a bit awkward unless it's a very compact drill/driver unit.

    Many have made fun of my little Snap-On CTS561 but it is perfect for what it gets used for. Still have to be careful not to cross-thread, strip, or poke holes in crankcases with a too-long screw :)emb:). I don't mind T-handles one bit, for machine thread screws. Once we get into the self-threading screws in plastic housings like the ones Stihl likes to use for handle bars or especially to hold backpack blower housings together, it's a different game. 12 of those bad boys per housing (at least!) and do half a dozen blowers a day,....... Don't forget you get to run them out AND back in. Still want to use a t-handle? ;)

    I will say this about the bits, get the best quality ones you can find. They last far longer and do a lot less damage to the fastener. Cheap bits, even Torx bits, either fit poorly from the get-go or wear quickly causing a poor fit and when the bit doesn't fit like it should, the fastener head strips very easily.

    I have a couple of Ryobi 1/4" impact guns I like to use. Light, great for dis-assembly & to snug things up. Then I hand "torque".

    I have occasionally wished for a tool like my little Snap-On with an impact mechanism in it. That part would preferably be switched "off" however for re-assembly. I haven't shopped in a few years now but I know the little screwdrivers have come a little ways even since I bought my little guy.
