Stripped Hole in Mag. Case

[Duane(Pa)]

I have a stripped hole in a non-critical Recoil Cover/Brake Pivot combo fastener. I was thinking Locktite or JB Weld. What would you do? This is something that is taken off, but not real often. It's a Stihl, with metric threads and t27 torx spline drive bolt. Thanks, DW

Heli coil?

I had the same thing , I filled the hole w/ JB and coated the bolt w/ grease and put her together. I have not taken it apart yet probably I will not be able too ?

JB weld, once it sets, drill it and tap it.. done

Timesert, a bit pricey at first but much better fix in mag than a heli coil. I have them in 3 or 4 different saws.

Timesert, in this application you don't need the whole kit. Just drill oversize and epoxy one in the hole. Very inexpensive.

heli coil or a timesert is the only way to fix threads. JB weld is as redneck as it gets and way easier to strip then the already easy to strip magnesium. heli coil is quicker then JB weld and is a permanant fix.

Helicoil if you have enought meat left on the case and if not they make a beefy steel threaded insert. If you work on saws enought this is a very commmon problem so haveing the taps and tools on hand is priceless. The Jb weld thing, may or may not last, depeding on how clean and texured the surface is for the epoxy to bond too.

Just tap it for an M6. A Timesert or Helicoil will require a hole larger than what you will need for the M6 bolt.
