Comb nails / groove nails are used in applications where nails are subjected to pull-out and shear forces. They are driven into the wood like a nail but hold like a screw. Beneath the flat head, there is a conical section, which ensures that the hole in the connector is always completely filled when the nail is driven in, resulting in a force-locking, concentric fastening. Application: Specifically designed for fastening wood connectors. The conical section of the shaft beneath the nail head and the grooves ensure precise force transmission in stainless steel sheet-wood nail connections.
