Camlock vs dzus

I have a panel that I am trying to ident. It is a section of cowl with holes for panel fasteners on two sides and rivets on a further edge

It was concertina'd - so now unbent and one of the holes has the remains of a fastener in it.

Looking at design it appears to be a Camloc rather than a Dzus or Airloc.

As the panel was painted RAF green - question is which RAF aircraft had Camloc fasteners - British manufactured or were they only used on US built aircraft?

It also looks a bit like the click-washer of an Amal fastener.

I can't tell the size from the picture, but it looks to me like the remains of a Fairey fastener, minus its flange.  Which could also explain the RAF green paint.

Thank you chaps - I have a Spitfire Mk1 cowl that has the hole for a fastener and a Fairey stamp and 30028 part number - so I assume it came with a Fairey fastener and it is too large diameter.

This one has a diameter of 16.5 mm at the main barrel. It has a steel slotted internal barrel that is attached through a steel shaft to the parallel steel bar.  Which sits in the stepped slots in the base- like the bottom of the camlock fastener. My assumption is that there is a spring inside and pushing down on the steel barrel and rotating it - moves the parallel steel bar.

It is not for moving but there is a void under the lip of the steel slot and the upper edge of the outer barrel has teeth around the diameter.

If anything it looks like a camlock but with the bottom housing included...

It was from a fairing  that was supposed to be from a Hawker Typhoon. I just cant see its shape on the Typhoon so was double checking via the fastener to see what it may be . I attach some further pics

There are no rivets on the edges of the holes in the fairing that would have held a fastener structure.

short update - after soaking over night it separated into two of three parts.

The shaft - with a collar that is still attached. The collar went around the hole in the fairing - the shaft moved down against a spring.

Second part is a tapered alloy tube with stepped base.

So from the diagrams - looks like a Camloc with flanges that went into the two parts.

So were these used on Typhoon fairings ?

Thanks for  your interest.

Good that you got them separated. I suggest that a look in the appropriate Vol 3 spares manual would be your best way forward to a likely I.D.
