Various roofing nails (shown full size).
Drywall Nails
As the name implies, these are for fastening drywall (Sheetrock).
The shank of the nail is partially barbed and the head countersunk
so that if the nail bites into the stud, it takes a good bite.
Drywall
nails
come in a variety of lengths for use with different thicknesses
of Sheetrock (see Figure 1-10).
Masonry Nails
Masonry nails
are cut (that is, stamped) out of a sheet of metal
rather than drawn and cut the way wire nails are (see Figure 1-10).
A masonry nail is made of very hard steel and is case hardened. It has
a variety of uses but the most common is probably for securing studs
or furring to block walls. Safety is important when doing any kind of
nailing, but, when using masonry nails, it is particularly important
to wear protective goggles to guard the eyes against flying chips.
