How a Screw Gun Works

• Like other screw guns, the DeWALT Scrugun resembles a power drill, and it works in a similar manner for inserting drywall screws. There are a few differences, however. Drywall screw guns weigh less than traditional drills, allowing the user to insert screws overhead with less arm fatigue. The most notable advantage of using a drywall screw gun, including a DeWALT Scrugun, is the ability to insert drywall screws without perforating the protective paper face on the drywall panel. The Scrugun features a "shoulder" that stops the head of the screw from going too far. The correct way to insert a drywall screw is so the head is just barely below the surface of the drywall, called "dimpling." A regular drill increases the risk of inserting the screws too deeply.
  
  

Benefits

• Using a screw gun speeds drywall installation, allowing the contractor to attach the panels quickly with one hand while bracing the panel with the other hand, or by leaning against it. Screw guns replace the old hammer-and-nail method of attaching drywall. The deep ribs on the sides of drywall screws secure the panels to the studs better than nails.
  
  

DeWALT

• The DeWALT DW257 Scrugun features sufficient torque to use for other construction purposes. By removing the protective drywall "nosepiece," the builder can use the power tool to insert wood screws into decking. DeWALT claims that their Scrugun is ergonomically designed to provide additional comfort.
  
  

Considerations

• Any drywall screw gun with a protective shoulder and sufficient torque to insert screws into joists will do the same job as the DeWALT Scrugun. When buying a drywall screw gun, compare weight and the manufacturer's warranty, in addition to the cost of the tool. A cordless screw gun offers the user the ability to climb on ladders and scaffolding when installing drywall, but it also requires frequent battery charging.
