New Zealand-made silicon bronze flat-head nails, 30mm in length, with an annular (ringed) grooved shaft ensuring a tight grip.
Otherwise known as "gripfast" or ring barb nails. Ideal for boat building and applications such as decking and securing roofing tiles, shingles, etc.
This nails are great to use. They are well suited to my lightweight sailing/rowing punt.
Perfect for the project that required non magnetic fasteners.
