Polo Rad self tappers
I have yet to find the correct self tapers for the Polo Rad fixing points. The ID of the hole is 4.8mm and about 12mm deep. All the self tappers I
have looked at so far are to small.
I have in mind that I need some hex head self tappers that don't have point but are more like the screws used on PC cases (but bigger).. No idea
of were to get them or what they are called.
I only need 4, if any one has some spare form fitting a polo rad I am happy to pay postage/beer money for them..

I used big fat pan head self tappers cut to length with the end rounded off - have a look in B&Q or Homebase for one of the little packs of 10.

I tapped the hole to about 5mm and then fitted normal m5 hex head bolts.

The best screws I found were M6 cap head machine screws, these go into the plastic very nicely and are very firm. I have also removed these on several
occasions without problems. Length I used was 20mm

I didn't tap them. The M6 screw went in without doing so.

I got some from the local motor factors... I measured the dept of the hole several times, and cut off the ends of the screws before tightening them up

i used some m6x20 , straight in with out any tap - no real need to tap it.
i supported my rad from below, so the top two bolts only stop it flapping about.

I wound M6 bolts in without tapping, had them on and off a couple of times and they still hold nice and firm.

M6 Tapped and 12mm long stainless steel machine screws for me.
Are you all sure 20mm is not too long?????????? The holes in my rad were DEFO not that deep.
If it looks wrong it probably is wrong.

I may have some Cortina wing fitting screws at work although IIRC they have a point that may do the job if you want them.
