whats their real name?

[naughtyboy]

found a couple of what i know as stud hangers in shed.
they are blue screws that go in to walls etc and have an internally threaded nut on top that studding screws into.
we used them at my old place to hang pipework from the ceiling as well as trays to carry the wiring.
cheers

[naughtyboy]

robotstar id love to but used my last couple to fix some battens to wall.
and been kicking myself since that i didnt get pic of them as thought just type stud hangers into search and up they will pop.

sent e-mail to mate that worked with me and this is all he could find but they are designed for use in wood.
identical to what i need but need to be for concrete to hold some studding in a concrete roof.

Tapcon

These are both Tapcon style fixings, drill ahole and screw directly into concrete Brick etc, no plugs, no two pack magic fillers, just direct in.
