Topic: Oil pump face plate screws

[paul_D]

Could someone please tell me what the screws are on the face plate of the oil pump (circled in red in attached image). They are Flat or Oval head, but what is the dimesion of the screw and type ?  Mine are stripped and need replacing.

Best regards,
Paul

N.B.  bike is a '72 CB500 if it matters

Honda should still have those screws available.  Replace oring while you're at it

Thanks, but I'd need the part number to go to honda though.

The 46x2 oring is already on my list of parts I am ordering

 M6 x 20, oval. I just replaced mine.

counter sunk screws

Dave it's odd but they are called oval now instead of countersunk. I was so confused when I couldn't find countersunk fasteners when looking through the bins at the auto store. I finally found them labeled as oval, and it was the same at the  hardware shop. When did this change?

[dave500]

it changed when someone decided oval was easier to spell than counter sunk?

Flat head and oval head are both for countersunk holes, but oval has a convex face. I think the screws are probably really flat heads, Honda used oval head for decorative stuff but the oil filter is not really a decorated unit.
