Drive flange bolt spring washer

The rear drive flange bolts have thread lock rather than a spring washer, any reason I shouldn't fit a spring washer?

I wouldn’t think it would be a problem, but why not just use threadlock ??

New bolts will have "nylock" nuts with them.

I haven't got new bolts and I am not confident I will get the holes clean and dry enough to rely just on the thread lock.
The earlier vehicles had spring washers I do believe.
Spring washers only cost pence from the local nut & bolt shop.

drive flanges are surely into the hub and do not have nuts on?

I would still use threadlock. I use both on mine, there is nothing to lose by still putting threadlock on it. I am also not sure how clean the hole needs to be for threadlock to work properly, i just give the bolt a quick wire brush and has worked well enough up to now.

You could run a tap through the hole and then give them a blast with brake cleaner or similar. Spring washers wouldn’t go amiss if you wanted to use them though.

Ah yes, my bad, thinking of prop flange bolts I was.

Thanks for the replies, will get some washers on the way home from work, already have some thread lock.

Blimey they were expensive, £1 for 30 of them!
Got home and while looking for something else I found a bag of them I must of previously bought!

If you can get quality spring washers go for it most of the ones about nowadays seem to pop out the side as you tighten the boat up!

funny I was complaining about just that on the m16 spring washers i bought to fit wheel weights to my fordson. seemed to be a quality control issue though as about every 1 in 4 would actually work correctly so I got there I the end it just took the whole bag!

I bought some different sized stainless ones a while back from Toolstation. They are nice and thick and are good quality believe it or not. I have a nut and bolt supplier not far from me who has been going since Jesus was a boy. The difference in quality of his stuff is very noticeable though compared to some of the Chinese sh*te on the go. They just don’t seem to rust the way the chinesium stuff does.

Just need to make sure they go on the right way now

2 out of 5 failed so a pretty high failure rate.

I think I have been a bit unfair on the spring washers, I came to realise my torque wrench was over tightening everything. Its now been thrown in the bin.
Did the other side with a known good torque wrench and had 100% success rate with the washers.
