Hi, I have the below Titan Chainsaw (TTL632CHN) and have lost one of the two nuts that hold the chainsaw bar in place - they seem to work their way loose very easily and frequently. I have searched for spare nuts but have been unsuccessful thus far. Can anyone tell me how I'd go about getting hold of some please?

Most Engineer merchants should be able to sort that, nothing special about them is there. If nothing special, then use spring washer underneath or use a nyloc. Can't see them clearly enough in photo. In this link, they look like plain nuts.
Thanks KIAB, They do look like standard nuts to be fair, just haven't had to source such things before. Can you recommend anyone and advise how I'd know I was ordering the right thing, please?
I've swapped them between chainsaws before. I'm pretty sure they're just M8s. Check ebay for Chinese chainsaw guide bar nuts. Shouldn't be more than a couple of quid. Nearly all the Chinese chainsaws use the same components. Sometimes they're flanged, sometimes not. Yours look like the same style as the Stihl (not flanged). I've never seen nylock nuts used here. I think the nylon would melt. I wouldn't do that. Just tighten them up properly, before long they'll be threadlocked with resin anyway.
Engineer merchant most likely cheaper, flange type might be better as they self lock, so shouldn't vibrate free.
You may want to measure the distance across the flats before ordering (just to be sure). As you'll want them to fit your scrench (the screwdriver/wrench tool you probably received with your chainsaw).
Thanks btiw2 - that is really helpful. I'll get on to that now and let you know how it turns out! Cheers!
I think it's an M8 with an unusual pitch. I have the same problem. I've tried coarse and fine and neither fits but the fella at the garage rummages through a pile of old nuts and bolts and finds one for me when I lose one.
