What Is Direct Fastening Anyway?
Direct fastening is the process of forcing a stud or nail into concrete and steel. It is direct in that it eliminates any pre-drilling or tightening to expand an anchor. The most common form of direct fastening still has to be forcing a pin into concrete to fasten 2x material or metal studs for drywall.
The original form of direct fastening was powder actuated tools like a Ramset or Hilti tool that uses gun powder charges to drive the pin in. Following that, gas technology came along. Most gas powered tools are actually internal combustion engines in which the piston drives the pin. All have a fuel cell and either a battery or other ignition source. Originally designed for drywall track with a magazine, single shot tools have also been developed that offer a little more versatility. Lastly we have battery nailers. Only a handful of manufactures handle them, we handle the DeWalt version. So here is a brief rundown of pros & cons
