SPAX nails and screws for wood connectors
SPAX wood connector screws can be used as a replacement for grooved nails. In many cases, a higher load-bearing capacity can be achieved compared to grooved nails (applies to sheet steel thicknesses t ≥ 2 mm). Only SPAX wood connector screws may be used to attach the wooden connectors to OSB and flat pressed boards (chipboard). Important: Choose screw length so that the screw tip protrudes on the back of the plate. For optimal use, we recommend our SPAX T-STAR Bits.
Grooved nails are used where nails are stressed on pulling out and shearing. They are hammered into the wood like a nail, but hold like a screw. Under the flat head there is a conical attachment, whereby the hole in the connector is always fully filled when the nail is hammered in, thus creating a force-locked, centric attachment. Grooved nails are used for fastening wooden connectors, in timber construction, engineering timber construction, carpentry, construction shops, etc.
