Simple & Cheap Underbonnet Upgrade for GT/GC

[Doctor Houx]

I was fed up with the rusting black steel bolts holding the engine covers in place, so have replaced these with M5 stainless Socket head bolts and washers. Look much better IMO, they don’t rust or seize and cost was less than £10 off eBay for the 25 you need.

Should work with QPV too?

 

[Bladerunner]

Any link to the ones you went with please?

 

[Doctor Houx]

Here you go for the bolts. Washers are just M5 x 15mm Stainless

Not clear to me I'm afraid - can't see 15mm in the list for the bolts, and where are the washers?

It'll be me, I'm as think as a whale omelette sometimes!

 

[Doctor Houx]

Any number of suppliers can provide these. Nothing special. Just search M5 stainless socket headed bolts. Length can vary but the original steel ones are about 15mm. Washers similarly are M5 stainless x 15mm external diam

Maybe I am missing something but on the Ebay link M5x15mm is not listed as an option

 

[Doctor Houx]

Sorry, it’s M5 x 16mm I used. 15mm is the ext diameter of the washers. Sorry for confusion

 

[Wanderer]

Got a link for the washers? We need to be hand-held!!!

Select option M5 x 15mm OD and pack of 25. Just the right number inc the 2 small panels at the back of the bay that need 3 each

I would have thought that these might be better, flanged socket heads means no need for separate washers. Shame they're not black. https://www.ebay.co.uk/itm/221301853865

I like the shiny ones!

I don’t understand the need to surround the engine with a small airfield.

Perfect Bladerunner. I ordered the bag of 50 so happy to supply two others. Will leave them in my car for the next meeting.
I do like shiny, so silver would be great. Have dropped several fasteners into the engine bay so 'built in' washer is a must. The word flange in the description is irrelevant.
company are UK and state "made in house" so keeping my effort to avoid Chinese manufactured tat.

The tie-downs in the boot of a QP rust like **** too, so replacing them similarly would be a good idea.

I've been thinking about something like this. Originals are shouldered and flanged - someone did point out that bike fairing bolts aren't bad - eg these at three quid EACH!
I think I like those black ones though...

the screws i bought are not ideal for the under bonnet cover. The built-in 'washer' is smaller than original fastener. Also the original fastener has a shoulder to prevent the cover ending pinched when tightened.
they are a good fit for the grille though
