Trurnit-Ring shank nails
with countersunk head
Ring shank nails, also known as annular shank nails or deformed shank nails, are used in instances where the nails are under serious strain due to pulling out and shearing.
They are inserted with a hammer or nail equipment as any other nail but due to their grooved thread, these nails reach much better extraction values in wood than nails with a smooth shaft.
They are primarily used for fastening steel sheets and steel sheet moldings (wood connectors) with wood in supporting structures.
If you are looking for smaller sizes, take a look at our facade panel nails. They have also a ring thread, but are slim and short.
