Bolts and washers ?

[Trevor Booth]

Very true Paul, you may notice that in an earlier post I said that in some instances I used Mild Steel bolts, this is purely so the bolt can be proofed correctly where using a higher tensile bolt and higher torque to proof the bolt results in damage to the components being fastened. I also use them in some areas where it is better for them to bend rather than break (if you hit something !!)

This has been an interesting running discussion. It is always good to know "reasons behind the methods."

I am in the middle of some suspension work right now and would find it helpful it someone could also give a little discussion about marking paints for nuts and bolts to give a visual indication if the fastener has stayed secure. Are there preferred brands of paint for this purpose?

My bad,

I forgot to mention the other two types of lock nuts which unlike nylocs work in high temp areas. .

Split beam. The split-beam locknut has slots in the top, and the thread diameter is undersized in the slotted portion.

Deformed thread. The deformed-thread locknut is a common locknut, particularly in the aerospace industry. The upper locking area is oval shaped.
