*Posted on behalf of a Hilti customer:

Can you recommend a powder actuated fastener for attaching a 2x4 or 2x6 wood framing to a concrete slab?

Hi Andy,
 
The depth of penetration into the concrete for the X-CF and X-CP fasteners will be the shank length, 2-7/8”, minus the thickness of the wood that is being attached. Please reference Section 3.2.10 of Hilti’s Direct Fastening Product Technical Guide for further information.
 
Regards,
Ashley

Hi Customer,

well this is a good question. The 2-7/8" Hilti X-CF and X-CP fasteners are specifically designed for attaching wood sill plates to concrete substrates. Hilti offers a suitable fastener for most sill plate application conditions. The carbon steel thick coated X-CP 72 P8 S23 fastener complements the Hilti powder-actuated fastener portfolio specifically for sill plate applications where pressure treated lumber is being used. Here is the link to the technical data for the X-CF and X-CP fasteners.

The X-CP fasteners are suitable for use with pressure treated lumber sill plates. Reference General Guidelines on top of following page for fastener recommendation dependent on environment conditions and lumber type used. The X-CP fastener has a pre-mounted 0.905" (23 mm) 16 gauge washer for fast and reliable installation. The X-CP fastener has an additional plastic washer that minimizes coating damage by the washer during installation. I hope I have answered your question. If there is anything else, please let me know.

Cheers
Justin

How far into the concrete do these fasteners go? PT can be as close as 3/4" from the surface of a typical PT slab. Wondering how much cover I should specify for new designs.
