Bolt science.

An interesting site for those inclined towards the engineering stuff. The link in particular is vindication of my long held view that spring lock washers are total rubbish ( click on the video test link) The rest of the site has some really interesting fastener information and worth a study. Yes, I dont have a life:)

I’ve never thought that those sort of washers were much chop but never had any evidence to prove it. I use Schnoores in most applications I feel need it, backed up often with Loctite 243.

I saw something on a special split washer recently.  Here is a test that shows several more locking solutions, including the Nord-Lock.

 

 

This test also shows that nylock bolts do pretty well.

I feel better, already,  being given to caring about these sorts of things.  :luigi:

Nuts to you, too, gentlemen! :rasta:

There is nothing wrong with redundant systems in critical applications.

Cool vid, but if our bikes vibrated like that, we`d be little more than a pile of jello in the saddle with-in seconds.  :o

I wonder how long it took the engineers to find the right frequency to prove their product over others, excellent marketing.

Lockers and lock-tite do just fine, and everyone checks their nuts now and then, right.  ;)

Yeah, those are killer. I use them on the crown wheel of small blocks. Really pricey, though.

 

 

not as bad as I expected Chuck.. ..if you don't need stainless

I'm ordering an assortment of these https://www.mcmaster.com/#standard-washers/=1ct7gj8  It looks like the bevel spring lock washers and schnoors are the same thing.

I had a front motor mounting socket head bolt unscrew itself and fall out recently. Oddly enough it had no affect on alignment. I only noticed it missing when I had to take the motor out last year.

 

all good vid's and info btw. the knowledge "bear" should be poked once in awhile.

 

 

Edit;  I see the links don't get to the place I wanted to show. you'll need a couple more clicks sorry
