peter I have some hex blanking screws that I used for the rear and fore sight holes on my PH 1100.
you just need to file down the underside to correct depth. still leaves a hole that you can fill with black wax if you want
I have some spare and will dig them out, you are welcome to them if you want to pop round
Oh dear .......... Cheese head screws are the normal slotted one flat on top with a counter sink head to sit flush. That's what they called them when we were doing wood work at school................................ ahhhhhhhhhhhhhhhhhh let's just say some time ago .
That is a countersunk screw, cheesehead looks like a 'cheese' no countersink top and bottom parallel.
Thank you Joe it's been a long time and some times we all have brain farts.
of course your correct. For some reason i was thinking wedge of cheese.
I don't even LIKE cheese!
what, not even Wensleydale?!
