I've been in search of stainless steel staples to wrap up a boat
restoration. The staples will be used to apply upholstery to the various
wood pieces (seats, side pockets, side rails, etc.). I have access to a
Craftsman pneumatic staple gun, model 351 (184080). The manual for this gun
says it accepts staples with a model of 18330, 18331, and 18332. These are
likely Craftsman part numbers, but I'm not sure.

The gun shoots 20 Gauge 1/2" crown staples. I would guess I'm looking for
1/2" length staples, but would probably settle for anything close.

It appears most stainless steel staples out there are for outdoor
construction, being 1" + in length. I imagine there's a company out there
furnishing staples to the marine market... where it is I have no idea.

Thanks in advance for any suggestions.
