Question

shooting treated sill 2x4s into concrete


when i shoot 3-in coated nails w/out a washer to fasten pressure-treated sill 2x4s into concrete, is it normal to have the nail head stick above the 2x4 for about 0.25 in, i.e. the length of the orange fletching ? i.e. what sticks above is the nail head + the fletching.

thanks,

I agree with PKHI. I've had the same thing happen to me. I've shot the nails in the concrete in my basement and it did fine. I went to help a friend out and had to go to a stronger blank.

Yes.
What you want to use is: Gun Cleaner, and gun Oil.

I suggest that you simply use the combined solutions (cleaner and lubricant). Walmart sells small bottles of different solutions.

Clean the fastener after every use.

The reason being that you are using powder actuated caps that produce carbon powder residue (like in firearms). That powder, if not cleaned, will damage and jamb up the operating function of the tool.
We keep a small sprizter bottle and rags in each fastener's case.

Hammer won't work, you can't hit the nail hard enough and straight enough to make it sink into the concrete once it's already in there 90% of the way. I had the same problem, the max load yellow caps wouldn't quite drive the long nails fully into the hard slab. Mostly I lived with it, we're talking sole plates and the mostly driven nail had them tightly pinned to the floor, with studs on top the wall isn't going anywhere . After a while I got some shorter nails, 2.5 inchers will go in all the way in a hard slab.

Or move the the .25 caliber gun

Agree with the 2 1/2" nails and also the addition of construction adhesive.

What kind of gun are you using?

I first used many years ago a Remington from the infamous retailer, it was a P.O.S. Spent some really money on a Simpson PT27, gun actually is quiter, less shot issues.

It can all be in the quality of the tool

That's a .27 cal. uses auto feed fastener strips. We have one.

Make sure that you clean it up good and use the correct power loads for the gun.

If you leave a nail up, you can cycle the gun and place it over the nail and give it a second shot....sometimes concrete is just a bear to shoot fasteners into....I use Ramsets, and they usually hit it the first time, except on steel. The double tap is not really recommended as being good for the gun. Take care with anything you do when using a power actuated fastener.
