Guys, some advise please, currently looking at some 3 point harnesse where the top mounting is the clip type.
The bottom 2 mounting holes are bolt in and my question is will they pass SVA with a clip type top mounting,
cheers, Chris

They will pass with either provide that there are no sharp edges and the bolts/eyes are marked 8.8 grade or above.

What Nitram said - min 11mm bolts

^^^^ or imperial equivalent of 9/16 (UNF usually)

On the same subject as harnesses, I need to fix mine to a horizontal member that I have welded on to my roll bar. The question is can I just weld a nut to the bar or have I got to weld a threaded tube into the bar?

Regards Steve

ISTR it has to be the threaded bush due to possible bending moments distorting the tube.
They are available from MK and probably others. I used these with no problems (except drilling 22mm holes in my roll bar - had to bring to work!!)

Thanks for that Marcus.

Will try their web site.

Regards Steve
