CNA-S

Connector Nail Stainless

CNA-S nails are annular ring shank connector nails with a conical shape under the head. These are identical to standard CNA nails but are made from A4 marine grade stainless steel. These nails are recommended for structural assemblies and installation of Simpson Strong-Tie connectors to timber, in order to obtain the published load bearing capacities. All tests were performed with this type of nail. CNA-S nails are stamped ≠ "no equal". Suitable for use with stainless steel connectors and in severe weather environments.
