372xp muffler bolts HELP!!!

[komatsuvarna]

Lookin to remove muffler on 372 and cant find a allen wrench to fit! Best i cant tell it looks like a allen head bolt with a pin in the middle of the head. Any suggestions? Baileys sell a wrench? Thanks

Hmmmm. Must be a tamper-proof allen head. Might be tough to find a suitable tool for that. Your Husqvarna dealer might be the best bet.

Should be 5mm, unless they changed them on later 372's.
If you don't have a long one, use can use a 3/16"

I've never seen tamper proof bolts on a muffler. The only place I've seen them is on the transfer covers of a 359.

Thanks metals406. Thats exactly what i need. Holy cow, 22.00 for a set of 6 metric bits. OUCH!!!
Brad, I know youve seen way more saws than me, so i dont feel so bad now. The 4 screws on the outside is regular allen head bolts, but the 2 that hold the muffler to the jug is definitely tamper resistant allen head bolts. Beats me

You're welcome. . . As far a sticker shock, Wiha tools are top of the line. Ask Brad Snelling about investing in saw tools. :jawdrop:

I am reviving this old thread because I've run into the same type tamper proof bolt on this 2017 372XP X-torq. The two screws set deep in the muffler are tamper proof hex heads. I've searched high and low for either a set or a single, 4-6" long, hex, tamper proof bit (or L shaped key). Does anyone know the size used on these saws? I'm assuming its pretty close to the T-27 torx screws that are also on the saw.
Thanks in advance.

The two bolts going to the cylinder have a larger head than the rest of the screws. They are either 3/16 or 5MM, I can’t remember which. Or the later ones use T27.

The 372 X-Torque saws use a standard T27 torx screw. Been that way for several years. Never seen one that used a legitimate tamper resistant fastener. Not saying they never did though it’s certainly possible.

Might be time to order a security bolt bit set. Pretty cheap these days.

HORUSDY 32-Piece 1/4" Shan Extra Long Security Power Bit Set, 6" Long Tamper Proof Security Bits, S2 Steel. https://a.co/d/0manOLA

I bought these last week. https://www.amazon.ca/dp/B078M6KHRH The recent flooding in the area has delayed delivery. It ill be interesting to learn how well they hold up, "S2 Steel construction".

Got some long torx bits for my inpact off of Amazon a couple of years ago and they came with the hole in the center and have lasted for a long time, don't know where they are made but really good tool steel- worked on a lot of 372 and 390's and have never seen a tamper proof mufler bolt, must be something new, I would change them to regular allan myself when you get them out..

They should be M6 screws and they take a 5 mm bit, never seen insex security bolts, torx are more common(?) and you can usually find a torxbit that fits in a allenhead screw. Maybe a t40 security bit?
