Two different types of concrete screw - which one should I use?

[AVR2]

I need to fix wooden battens to concrete fence posts. Screwfix has two different types of concrete screw - ones with Torx heads with a thread pitch that looks like regular wood screw, and screwbolts that have a *much* wider thread pitch.

The screwbolts are significantly more expensive. Is there any good reason for me to choose those over the Torx-head ones? There's nothing particularly special about the job, I'm just adding some wire mesh panels between the battens to make the fence higher as fox-proofing.

I have used the torx ones and find them very good

Thanks - that's what I wanted to hear

If your only fixing battens screwfix sell a lighter duty one that requires a slightly smaller hole ,from around 40 to to i think 130mm

Agree with above. The hex head screws are for structural load bearing situations. The torx screws will be plenty - either one. Beware though that they are dependant on the pilot drill and the material being drilled. Fence posts should be fine because the concrete is a good density, but in some other materials 0.5mm either way on the pilot drill can make the difference between a good fixing and not.
