Dewalt first fix nail gun / Galvanised nails bending

[Gerhardt]

We are busy with an oak framed outdoor kitchen, we have green oak rafters and I am trying to nail 20mm air dried oak boarding onto the rafters. I bought 63mm galvanised wire collared nails from screwfix, but only 1 in 10 of the nails I shoot actually goes through all the way, the rest of them bends or the head breaks off. When I change the nails to no paper collated standard nails it nails it perfect. So my guess is it is the nails? Has anyone had this problem? What other brand of nails have you used in a similar situation. Will stainless steel nails at double the cost work better?

 

The attached photo shows the golden nails driving in perfectly but the galvanised nails almost all bent or broken.

Stainless steel nails with oak is a must. You can get good quality 34 degree full head stainless steel nails from nailers.co.uk (Alpha Pneumatic Supplies). But also check your nail gun settings.

 

Your other alternative is to use lost head stainless steel screws like these: https://www.tite-fix.co.uk/products/tongue-tite-plus/

Thanks for the reply, as I needed nailer on the day to make the most of the hour of no rain, I bought a paslode which is shooting the nails in with no problem.
