What to do if fasteners jam in my DeWalt Nail Gun?
- A
  Alejandra BlackAug 19, 2025
  If fasteners are jamming in your DeWalt Nail Gun, it could be due to a few reasons. The driver channel in the nose piece might be worn, requiring a nosepiece replacement. Ensure you're using the correct size and angle fasteners. A loose magazine can also cause jams, so check that the magazine latch is holding firmly. Lastly, a worn driver blade can lead to jamming, so consider replacing the Driver Blade Kit (Cat. # D512565 for 16 GA., D512752 for 15 GA.).

Why is my DeWalt D51256 Nail Gun skipping nails?

  Thomas ScottAug 25, 2025
  If your DeWalt Nail Gun is skipping nails, the issue could stem from several causes. First, ensure the air supply and couplers are not restricted. Lack of lubrication can also cause this, so lubricate the tool with approved pneumatic tool oil. Check if the nose piece screws are loose and tighten them with the appropriate Allen wrench. Make sure you are using the recommended size and angle fasteners. A dirty magazine can also cause this issue, so clean the magazine track and nosepiece. If the magazine is worn, consider replacing it. Finally, a broken or damaged driver blade can also be the culprit, so replace the Driver Blade Kit (Cat. # D512565 for 16 GA., D512752 for 15 GA.).

  If your DeWalt Nail Gun is showing a lack of power or is sluggish, several factors could be the cause. Begin by checking the air supply to ensure it's not low.
