LOCTITE - "Heat Resistant" for cylinder head?

#1 PostAuthor: Pigford » Mon Apr 27, 2015 12:14 pm

I'm after some hi-temp LOCTITE (or similar) to lock the M10 grub screws in the cylinder head on me Z1000. I've drilled & tapped the air emission passages and want to fix them in place - air tight & secure :!:

Any previous experience on summink that works, gents :?: Ta.

Loctite 641 would be adequate.

If you never want them to budge again I have a spare small tube of 648 that you can have if you PM me your address. 648 is good to 180DegC which might be enough?

Loctite 272 will do 200 - 230c

I have an equivalent, around £8.00 for a 50ml to a fellow forumite :)

Be about a week though :??

I use it for securing bearings in cylinder heads, gearboxes and axles, also for retaining bushes in power valves and valve guides - never had an issue - have to heat them with a naked flame to remove them.
You can go up to 638 or 648 180°C or 278 +200°C.
