Identifying a 110mm x 6mm frame fixing

Can anyone identify the manufacturer and range please? I'd like to replace some corroded ones with exact replacements if I can. Compatible accessories would be handy too (i.e. decorative caps).

110mm 6mm Frame Fixing

They are 110mm long Pozidrive CSK head with a 6mm dia thread/shank. The shank is 45mm.

This does not appear to be a common length/thread combination, but i hope to be told otherwise

As a supplementary question - why would the side fixings (in a uPVC door) have the rawlplug installed through the uPVC frame and therefore just showing, but the floor fixings do not? The lower fixing clearance holes are big enough for the shank, with the rawlplug not visible at all.

Use stainless for no rust.

As for floor fixings ,probably just knocked them a little deeper.

Thanks Foxy! I will get SS, but a couple of queries, if I may...

Does the wood screws thing imply these were not originally frame fixings, i.e. with a supplied full-length rawlplug. Or is that reading too much into it?

As for floor fixings ,probably just knocked them a little deeper.

That's my point. The floor holes in the door frame are only large enough for the screws, not for a disappeared rawlplug. I think there's a rawlplug down there somewhere, but that must have been fitted before the frame somehow. Hmmm - tricky!

This is in clear contrast to the sides which have been drilled with a clearance hole for the rawlplug diameter.

Frame fixings are poor in timber frames and even worse in uvpc , they probably failed to hold so we’re replaced with wood screws.
Doubt the holes are different sizes the walls in frame fixing are very thin and uvpc tend to flex a little so frame fixings don’t go fully home .
Concrete screws are far more secure , no plug involved .
