Here is a brief video showing how easy it is to fasten a 2×4 to steel using your Hilti, Ramset, Simpson or DeWalt powder actuated tool.  In the video we are using a Ramset Cobra, the Ramset SP178 Power Point pin and a red power load.  A few words of caution: Safety first, make sure you have appropriate safety apparel including safety glasses and hearing protection.  Don’t get to close to the end of your 2×4 or it may split.  Also, keep in mind that the Ramset SP178 pins are not for use in treated lumber.  Check out the video below and watch through the end to see the slow motion side shot, it’s kind of cool.  You can find the pins online at ConstructionFastening.Net
