The proper way to do it?

I don't suppose anyone on here knows the proper placement of a metal washer?

I have a machine screw bolt, a matching steel washer and a hex nut to match the bolt. I'm joining two flat pieces of metal with the bolt through the hole in each piece of metal.The situation will be exposed to vibration. I'm tightening with a hand spanner (wrench) so the torque is not an issue.

Should the washer be under the bolt head? Or should the washer be under the hex nut?

Now Zen, but a +Net residue.

The nut, and preferably a locking washer of somesort if it's being used in a situation where it'll be subject to vibration...

Nut side, especially if one is securing the bolt with pliers while tightening the nut.

Thank you. I was having a white hair moment. I'm using Loctite Flexible to handle the vibration as the kit I'm using has few locking washers.

How about a Nordlock washer?

 

There much better then a Nyloc nut or threadlocking compound.

Re: The proper way to do it?

I'm just cautious about vibrations and bolts myself, my mower had its blade bolt shake loose (probably should have been loctite'd at the factory, but wasn't), and I sorted it out by adding a locking washer between the bolt head & washer that was already there, hasn't come loose since... Smiley

Re: The proper way to do it?

Thanks all. I've now finally finished assembling my planer/thicknesser. The process was made a lot more fiddly than it should have been because of the assembly instructions.  Poor photographs of the parts used and where they go. It was as if they'd been written by someone who's done it a thousand times but doesn't look at it from the view point of someone doing it for a first time.  Some of the assembly processes were not possible as described. A British made unit! The guide should have been better.

SWMBO will be chasing my tail for the woodworking jobs I've been putting off.
