The round head strip nails 21° are designed for indoor use within service class 1 (DIN EN 1995-1-1). The nails are galvanized for corrosion protection. A resin coating also allows the nails to be pressed into the material more easily, ensuring better hold. The 21° connection angle and the ribbed shank shape provide a durable and secure connection in wooden constructions, for roofs, boxes, and pallets, as well as on door, window, and furniture frames. All nails are manufactured in Europe, ensuring high and consistent quality. They are compatible with Bosch pneumatic nailers.
