Herald / Vitesse bootlid screws

[Colin Lindsay]

One of mine has snapped off in behind due to rust and the other needs removed to repair a slightly rusty bit on the 1200 bootlid, so will probably have to be ground off too. These are not shown in any of the parts manual diagrams but the parts list gives part number KX4504, which according to data I've found online is a setscrew, flat, countersunk, 80 degree head in No10 UNF and 1/2 inch long. Can anyone confirm No10 UNF in Imperial fractions? I'm not too worried about matching anything as if I get close I'll just replace all four, but would like to get it as close to original as I can; after all they're quite visible on the bootlid.

No. 10 is 3/16" - you'll sometimes find them listed as both but some places insist that there's no such thing as 3/16" UNF (but are quite happy to sell you a No. 10 UNF)

Thanks Rob - located and ordered online.

on mine the screws had been loose for years and the holes were awful  tried a stainless plate but it was a tensile fuel tank strap and you could not cut it so

repainted a shallow domed coach bolt , this covered the messed holes and didnt look to out of place hardly original but solved a fix.  know one ever noticed  Ha

Hi Colin!  ref these screws, have you thought about cup washers assuming there holes are small enough?

[Colin Lindsay]

Once the bolts arrive I'll see what fits, Martyn - the actual bootlid itself is cupped where the bolts go through; I had to grind all four off earlier and it actually did occur to me to look for washers on the outside as well as the inside, but never found any. I think washers will be a good reinforcement once I get the rusted-through section repaired; I seem to have a few lying about so hope they fit the new bolts.

I have seen them at a "Fastners" and if I recall a "Caravan Shop"  Ebay have "Landrover Damper convex washers", and "Apica Euro style Motocross convex washers"

I nipped out there for a quick photo (absolute downpour going on at present!)

The corroded side was behind the boot stay bracket; it has cleaned up very well and needs just a little tack / fill in to restore it. The other side, with no stay, is mint. It may be an idea to have a cup washer welded into place and the surrounding metal built around it; must go rummage and see what sizes I have.
