Trivial question - Nylocs vs spring washers

I worked in a garage in Ireland once (briefly) and asked the boss where the torque wrench was..... he just laughed and said 'this is ireland, do them up tight then a bit ****ing tighter'!
Very sound logic. Anyone who's nuts keep coming loose should not be allowed to own spanners.

There are plenty of YouTube videos comparing the use of lock washers and or nylocs and vibration.
This video may not be the best example since their company is trying to sell their washer but jump to 2m29seconds...

I used Nordlocks on a job in Aberdeen this year (and subsequently one in Liverpool). The engineering and safety guy specked them. They tested spring washers and nylocks. They are astonishing but we had about 4 thousand nuts to tighten (all torqued to the correct value) and it was a difficult working environment. Being able to spin the nut down the thread quickly was a godsend it must have taken a couple of weeks off the job. Down side the local stockist only had mertric and as they are Scandinavian I doubt they do imperial and cost about 30 pence each, generally speaking we had two one on the nut and one on the bolt head. So yes nearly 2 and a half thousand pounds for washers. For this job worth the money for a Land Rover rebuild I'm not so sure. But If I was campaigning a Land Rover in off road events I'd have them for sure to be able to make that quick fix when needed.

Difficult working environment and for f@cks sake drop nothing

Split washers are designed to "dig in" when unscrewing, but if you have them torqued down flat, the edge has gone anyway. So in theory they don't protect so well initially.
I thought nylocs could be used more than once, but it makes sense they just won't be as good second time around. I regretted using some small nylocs on fiddly job recently as I had to ratchet them all the way down and it took twice as long as it should have done.

Absolutely hate flow forge. Happier walking across an RSJ a few hundred foot up than Flow forge more than 10ft of the deck.
