Framing nail guns are essential tools for carpenters, framers, and construction workers. When used properly, they can greatly increase productivity and efficiency on the job site. However, even the best nail guns can run into issues – like a framing nail not sinking all the way into the wood. This can be frustrating and costly if you have to go back and manually sink hundreds of stubborn nails. So what causes this problem, and how can you fix it?

Incorrect depth settings

Most framing nail guns allow you to adjust the drive depth via a dial or selector switch. This controls how deep the nail will countersink into the wood with each shot. If the depth isn't set properly for the material you're nailing into, the nails won't sink all the way. Make sure the depth setting matches the thickness and hardness of the wood material for complete fastening. The right nail depth for OSB won't be the same as for framing lumber or other products. Take a test shot first, and adjust the setting as needed.

Incorrect Nail Size

Number two on our list, the use of incorrect nail size. Every framing nailer has different specifications for the size of nail they can drive. Using nails that are not the recommended diameter or length can cause the tool to malfunction. It is important to check the owner's manual for your specific framing nailer to see what gauge and length of nail it requires.

The length of the nail from top to bottom and the diameter of its shank can vary by the type of framing nail gun and manufacturer. Using the wrong diameter or length fastener can lead to nails not being fully driven, or not being driven period - as the nailer is likely to jam.

Low Air Pressure

Air framing nailer require sufficient air pressure to drive the nail into the wood with enough force. Most framing nailers need 70-120 PSI to function properly. If your compressor isn't supplying adequate pressure to the nail gun, the nails will not have enough power behind them to penetrate the wood. This can happen if there is a leak in the hose or a problem with the compressor itself. Make sure the air hose is tightly connected to the nail gun and compressor. Check that there are no leaks, kinks, or cuts in the hose that could cause pressure loss. Test the air pressure coming out of the compressor - if it's low, service the compressor to get the pressure back up to spec.

Hard Material

Framing nailers are designed to work with certain types of wood, and if the material being used is too hard or dense, it can cause the nails to not sink properly - or at all. Some hard materials such as exotic hardwoods, engineered lumber, or laminated veneer lumber (LVL) can be challenging for the framing nailer to drive with enough force to leave the nail head flush with the surface.

It's important to be aware of the material being used, making adjustments accordingly to ensure the framing nailer performs to its fullest potential.. Not all nailers have a driver that is powerful enough to sink properly in LVL.

Grease and Cleaning

Less common, but still relevant, you may find the presence of built-up grease inside the tool. Several new guns come packed with grease, so it's important to take the nailer apart and clean it properly before use. Once cleaned, add pneumatic tool oil and try again.

Worn-Out O-Rings

Worn-out O-rings can also cause a framing nailer not to sink nails properly. O-rings are responsible for sealing the tool and keeping the compressed air inside, and if they become worn or damaged, the tool can lose pressure and malfunction. Make sure to check the O-rings on your framing nailer regularly and replace them as needed.

Broken Drive Pin

Another issue that framers face is a broken or chipped drive pin, which can cause the nails to be driven at the wrong angle or left sitting proud. To check if this is the case, pull the nose off the gun so you can see the end of the pin.

This can happen due to wear and tear of the tool, or due to improper usage of nails. If the nails are too long or too short, it can cause the drive pin to break or chip. If you notice the drive pin is flawed, it is important to replace it as soon as possible to prevent any further damage to the framing nailer.

Dirty or Blocked Air Filter

The air filter is responsible for keeping debris and dust out of the tool. If it becomes clogged, it can restrict the flow of air, causing the framing nailer to malfunction. Make sure to check and clean the air filter regularly to ensure proper performance.

Not Holding Nailer Properly

Consistent nail driving requires firmly pressing the nail gun tip against the wood before firing. This ensures the safety catches are disengaged and drive blade makes solid contact. If you fire the nailer without holding it flush and stable, the result can be underdriven nails. Always keep the nail tip oriented 90 degrees to the wood, and don't fire until adequate pressure is applied.
