Screwing ply?

What I've found when people have used ring shank is they sometimes work their way up and the heads become visible.

 

That sounds like they have missed the subfloor, Ive not seen that problem either. I find 20mm screws dont bite into 6mm ply enough, had to use 25mm and yes I was waiting for the burst pipe all day!!

 

20 mm every time !! By the time they have countersunk a little , they are just about right .

old floorboards are ok as long as they've not been sanded a couple of times before someone decides to cover it up...lol

 

Structural subfloor should be 22mm + really but we all know what builders are like

 

Why??

 

Cause the heads snap off really easy

 

Did some last year borrowed my builder mates driver with collated dry wall screws had to go through 2 x 9mm sheets to save time. worked a treet, no snapping.

 

We have a new piece of kit on the way screw fed on a plastic strip used from a standing position no loading screw one at a time, tried it in the unit it brill.

 

is thaqt the walking sticking looking thing?
Seen it in action at harrogate.
Great idea in practice
But a good bit slower in reality,

Yes i use mine like a machine gun lol

 

Because the threads are to open and they dont bite aswell as spax,

 

something similar to this.... http://www.makitauk.com/product/fastening/autofeed-screwdrivers/6843-auto-feed-screwdriver.html

 

correct, but now with a longer shaft and proper wood screws too

 

trying to find proper wood screws for those things is a right proper pita.
I know, had my auto feed for last 7+yrs

 

get you a price then shall I?

 

i only use two sizes
20mm & 25mm
let me know prices mate cheers
