Mushroom head screws

If the strips are going to be varnished before fitting a screw a separate washer of some kind would be needed to prevent damage to the varnish with the head of the screw when tightening.
 
Our boat was built with mushroom headed Philips drive screws. Thousands of 'em. Hard to find in the UK. I have never found a UK supplier. Try the States or (:devilish: China). Sorry, you can't have the little box in which our redundant screws are hoarded for future use!
 
Pondering covering the grp overlap on the bulkheads, I have produced some hardwood strips from free material milled to leave a small overlap on one edge using a spindle moulder.

I need to fix them to the bulkhead and some, at least, have to be removable as they support the headlining panels.

I am a fan of concealed fixings but, in this case, I am going for screws. Following the maxim, make a defect a feature, I am looking for mushroom head wood screws, stainless of course. So far, looking in vain.

Anyone help please?
Westfield Fasteners are a good source. Bapp Fasteners have most and will will get almost anything in for you if you phone or email them.
 
Bapp needs a phone/email contact.

Or use this:
Insert Nuts Type D M6 x 20mm 50 Pack

Now that is an idea.

And this:
Slotted Mushroom Head Screws M6 in A2 Stainless Steel - Westfield Fasteners Ltd

As in photo.

Or, if your wood is very good, just tap into it.

Probably will- The fixings will be in shear.

Or drill, fill with filled epoxy and drill and tap.

Edit

Well, well, well! Look what I found one my desk! Accepts the screws I have to hand.
Waiting to be put on ebay as surplus to requirements. Not now!
Many thanks - problem solved.
