Hi,

This weekend I'm starting a bit of drywalling for the new tank and airing
cupboard. Got a load of 100x50mm PAR ready and a plan on Sketchup...

I've already got a load of GoldscrewPlus screws, but having tested some, I
wonder if there's a preferred screw for knocking studwork together.

The GoldscrewPlus have good grip and self-starting ability, but fail to pull
the timber together well.

OK, drilling a pilot is one option, but I just wondered what pro's would
use?

No idea what pro's use, but the options a
- drill a pilot hole
- clamp the pieces together
- don't worry about it (does it actually matter if the pieces aren't
clamped together?)
- Depending on the screw size and the wood involved, if you just keep
screwing the screw may eventually cut a clearance hole. (The
alternative is that the screw head just sinks through the top piece).


If I had to pick one, these look promising:

Hi Martin,

My default option and probably the best bet. I was quietl waiting for a
chorus of "you want these" but that looks like it's not going to happen ;-

- clamp the pieces together

- don't worry about it (does it actually matter if the pieces aren't
clamped together?)

Extra strength? One part will form a load bearing "shelf" (it's a stepped
design as it's going into the inset where some stairs do a 90 degree bend).

Also, there'll be cross members over the tank carrying pipes and pumps so I
want these rigid.

- Depending on the screw size and the wood involved, if you just keep
screwing the screw may eventually cut a clearance hole. (The
alternative is that the screw head just sinks through the top piece).

I found that the head sunk but nothing moved...

Cheers
