Concealed fastener systems use self-countersinking screws and special bits that drive the screws to a specific depth.
A cylindrical plug made from the
same trim material is then tapped into the hole.
Nails should have a thin shank, a blunt point, and large head. Pneumatic
nails, should have a full round head (instead of clipped-head or finish nails).
Set the gun pressure so that the nails are driven just below the surface of the
board.
Use plastic collated nails: wire
collation doesn’t always break off cleanly and any remaining pieces of wire can
rust.
