These wood screws are in addition to chipboard screws and carriage bolts the most important fastening elements in the wood construction, dowel technology and wood fasteners of all kind used.
SPAX-screws is a German brand item, which is produced from proved materials in Germany. All important kinds of SPAX-screws are licensed and frequently internal and external examined. Only screws in green packaging and with the SPAX symbol on the bold head are original SPAX screws. Screws imported from Far Eastern countries are sometimes also wrongly as SPAX screws identified. The reason for that is that the brand name itself is used for the name of the item and also similar items. SPAX- wood building screws, with countersunk head and also wafer head are high quality wood screws with building control certification. SPAX- wood screws as well as Fischer wood screws guarantee best fastening figures and maximum hold in any case. You can differentiate screws by screws with cylindrical head, countersunk head or wafer head. For example, if you want to double woods to strengthen additional rafters, you should use a SPAX screw with cylindrical head. It's important to comply with the static values, which have to be calculated before hand. For general fastenings in the wood construction sector the SPAX with countersunk head or hexagon head is the right choice. For static fastenings, where a pull through of the head is possible, it's the best to use the SPAX screw with wafer head. Because of the bigger contact area of the head a maximum hold can be reached.
