I'm sick of getting saws that people have either lost half the bolts or they've replaced them with an assortment of different bolt heads.

I want to buy a quantity of bolts for predominantly Stihls, so I'm trying to find the ones that need a T27 torx drive. Can someone tell me the correct terminology for these? Are they bolts, set screws, machine screws?

I think they are M6 thread, but what would they be called? cap head torx or what?

Cheers,

Dan

If you ever do find the industrial source, I'd love to know. I looked everywhere, and never found them. They are a Torx head screw, and come in many lengths and in M4, M5 and M6 sizes. Then there are the "plastiform" type (secures into the plastic tanks etc), and then the thread forming type (like on the 025 crank case). Heck, I just go to my local Stihl wrecking yard and buy them as a mixed lot by the pound... every now and then.
 
I used to own a Renault Laguna and that seemed to be held together with these d a m n things too. I must be able to get them somewhere!
 
The closest I came to it was through a specialty aircraft bolt supplier, but he figured they'd cost even more them from Stihl, so I never pursued it. Sure are nice screw though... they never come out and rarely break or spin out the heads. I hate working on the old straight slot screw head saws now.
 
I suppose allen head would be the simplest alternative, ironic as I've just bulk bought a load of T27 driver bits :-(
 
You'll drive a future repair guy insane... and, they won't work (at least not reliably) on mag unless you use spring washers. The Torx screws have special gripers under the heads to bite into the mag casings (it's why they don't undo on their own). Allen head screws were used on Stihl saws for a while, but dumped in favor of the Torx screws

Buy up destroyed Stihls. They have about $30 of screws on them... I keep every screw from all the saws I break down and dump. You can buy a nice screw kit from Stihl - cheaper than buying each screw one at a time.
 
Whilst I'm in complaining mode, why is it that Stihl cylinders have the tightest access to the cylinder bolts.I end up having to open the holes up before I can get my driver in to the bolts. I even bought a Stihl scrench and that wouldn't fit.

A scratch awl (or tiny carb screwdriver) to dig out/ loosen up the packed crud followed by a sharp blast from the air nozzle will clear the screw head so the torx driver will fit without spinning out. I have to use the same procedure on the allen head screws on my Husky saws.

That's not what I mean, I mean that the holes through the cylinder fins are too small. I end up drilling them to open them up enough to get my driver through to the bolt heads.
 
D'ya think this is a little extravagant?

WHat is this kit called? Do you know the part/order number for it?

Thanks
 
America please try to keep up and go metric like the rest of the world
 
I just use the whia T handle it goes through the cyllinder holes just fine althogh you always have to pick out the saw dust before you can stick it in. I bought mine from baileys. Every torx on the saw can be taken off by that one wrench. I have and 031 that has an assortment of different sized allens and flathead screw on it and it drove me absolutly mad.
 
Dan there is a torx head t-bar that stihl makes to fit in fiddly areas like the cylinder head or you could cheat and get a long extension for a 1/4 drive ratchet and then find a socket that will fit the T27 torx bit and feed that down to the cylinder head bolts
 
Item No: WTL 36432

$6.95

This is the item you want from Baileys-online.com It is a T27 Torx that will work on the screws and get down into the holes drilled through the cylinders.
