Side Curtains ....fixings

[David.H]

Very helpful Thanks to all.
Looks like a 5/8" rsd csk screw or possibly 3/4 When I get to that stage I can experiment & see which actually bears on the peg.

WOW....that size would hold the side curtains onto the space shuttle for take off and landing!!!  

The ones Ruairidh shows are RAISED COUNTERSUNK (oval & instrument) 3/16" (ish).  Length 5/8" and with a 32 tpi (threads per inch) which would equate to a BSF. 

For the rubber washer inside....possibility is.....that black silicone (or similar) squeeze-out-of-the-tube stuff.  Grease screw, put screw into washer and fill with the silicone.  Put a bit of clingfilm on upholstery with hole over hole and screw the screw into retainer till a bit short of fully in against peg and wipe of surplus that has squashed out.  Allow to fully set and there you have a perfect fit rubber washer.  The grease should prevent the silicone from sticking to the screw so it can be twisted.
My Nippy screens have pegs that fit into the top of the door.  There are brass tubes with a head that sits on the door top with the tube going into the wood of the door frame.......nothing to hold them in place.......they don't fall out even at 80+mph.......the tops just flap outwards but a bit of string looped round the windscreen butterfly bolts controls that.

I did in fact say in my original post that the thread is 1/4BSF.....I have located some & will modify them so they don't fall out.
