Tek Screws Or Not?

[udon]

Can anyone give me a trade name or technical name for the screws below.

I was told they were Tek screws but they don't look like the Tek screws available in Aus.

Thanks

The nuts are called "wing nuts".

The washers are called "fender washers".

The studs could be called different things..."threaded wood insert studs" should do.

These are American terms.

chownah has summed it up.

a tek screw is used for a direct fixing into steel without having to drill a pilot hole it is a self drilling screw.

what you have here is for wood fixing.

They are called fender washers in the states and mudguard washers in the UK

Glorified coach bolts.

Looks like they are for attaching something flat to wood.

I know the studs as 'wood anchors' (UK term).

Thanks to all.

I couldn't delete the washers which seemed to confuse someone.
