Adrian Saunders Posted May 10, 2020 Report Share Posted May 10, 2020 I have just bolted my brake discs to some new, aluminium hubs and some of the spring washers have deformed as per the attached picture. I’m considering swapping to Schnorr washers as we use these at work, they cannot deform in this way and they still bite into the fastener head and part. Has anyone else experienced this deformation and changed the washer type? Link to comment Share on other sites More sharing options...
rogerguzzi Posted May 10, 2020 Report Share Posted May 10, 2020 Hello Adrian They are cheap and nasty spring washers made down to a price I have had the same rubbish probably better to use the old ones ? I have even put the set back on them by a gentle twist(still better than those!) Roger Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 11, 2020 Report Share Posted May 11, 2020 after many trials on truck assy we dumped all spring washers as useless back in the 80s plain washer and plain nut and torque control on every fixing won the day i would use a good plain washer and a firm loctite apply the torqure and forget the silly spring things , Pete Link to comment Share on other sites More sharing options...

They’re quite similar to a Belleville but they have serrations both sides. 1 Link to comment Share on other sites More sharing options...

All the old ones that I’ve removed from the car looked fine but as they’re so cheap one tends to replace anyway. Link to comment Share on other sites More sharing options...

Tony. Tony, we use them extensively at work. Our CEO swears by them and absolutely detests spring washers or a bolted joint without washers. The Schnorr washers are very effective. I’m in work tomorrow so I shall grab a few of each size to try out. 1 Link to comment Share on other sites More sharing options...

JohnD Posted May 12, 2020 Report Share Posted May 12, 2020 Learnt of Schnorrs during my Motorsport degree (chatting with instructor - not in a lecture, of course!). Teams will use only those, or an alternative, Heico, Nord-lock. Never, ever the split, spring washer. It's what I use now, on anything rotating.

I'm assuming they're metric, of course. Link to comment Share on other sites More sharing options...
