Here are some key advantages and potential limitations of using 34 degree clipped head nails:
Advantages:
Increased holding power
The angled clips provide greater resistance to pull-out compared to smooth shank nails.
Reduced splitting
The clips displace and compress wood fibers, helping reduce the chance of splitting in softer woods.
Easier driving
Can be driven directly into lumber without pre-drilling in many applications.
Top-down only driving
The clips make these only suitable for driving from the top down into lumber.
No surface marring
The recessed clip avoids marring finished wood surfaces like flooring.
Potential Limitations:
Not for hardwoods
The clips are more likely to split hardwoods like oak. Smooth or spiral nails recommended.
Unsuitable for metal connections
The clips do not grip or provide pull-out resistance in metal framing or connections.
Hand driving difficult
Not easy to hand drive compared to smooth shank. A nail gun is recommended.
Not for thin materials
The clip angle means these won’t work for very thin wood under 3/4″ thick.
No clinching
The head shape does not allow clinching or bending over the nails.
So in summary, the holding power can be useful but the nails have some specific applications where they would not be suitable due to the clipped head design.
