1.   Coated, threaded and ringed nails hold better than smooth shanks.

2.   If the fasteners are galvanized nails, the job is tough, because galvanized nails hold better than any nail.

3.   The adhesive might not stick to the paricleboard, and nails will not hold in it.

4.   The galvanizing process makes the nails hold well, and there are little barbs on the shafts that help hold even better.
