Production takes place in certified factories in Asia in compliance with European production standards.
All production batches are also subjected to AV24 quality control in Austria.
Each package of TENZ® wood building screws is marked with the AV24 quality seal (label on the bottom of the screw box). The AV24 quality seal guarantees tested quality. Only screws that meet the 24 strict quality criteria receive the AV24 quality seal.
The specified quality requirements for TENZ® wood building screws go far beyond the legal and market standards. The wood building screws are tested in an extensive test procedure – from the screw head to the screw tip.
