Undertray fixings

[brappage]

Hi guys, just wanted some opinions on what you have used when refixing the undertrays at the engine section / diffuser. The front and cabin section are well secured with rivets after being revealed previously. The self tappers at the rear had totally corroded over time and I have had to drill nearly half of them out. Thinking bout putting back with tek screws, the fixings used for metal sheet cladding to steel purlins, as below. Anyone used something similar or better? Want easy access to remove them in future for servicing / checks etc. I know there are cut outs but. There not ideal for everything. Cheers

Weld lugs on the chassis and use Zues fasteners, it's been done before

That is what I used in the stainless version 3/4" long to replace my screws and they work great.
I will use them if I ever need to replace the rivets.

I changed them for hex head 8mm 3/4" self tappers. Dont need self drilling.

I got a about 200 of them for less than a fiver in a local shop.

Happy to get some more and send them to you.

Just ordered some stainless ones got 200 for £9 but thanks for the offer mate.

Ordered.a rake of bolts and washers aswell for rebuilding all the arch panels etc. no more self tappers hopefully! Think self tappers and cable ties were on special offer the week mine was built

When you fit them put a little copper-slip grease on each one
