Construction + Civil Engineering

The fischer Group of Companies has recently launched the latest generation of the Power-Full II full-thread screws. These wood screws are ideal for permanently and securely connecting or reinforcing wooden constructions. They also offer the advantage of easy and efficient installation for challenging fastening requirements in timber construction.

Main and secondary beam connections, false beam edges, shear tension bracings or shear connections – PowerFull II is an ideal choice whenever timber connections or reinforcements are subjected to particularly high requirements. Available in diameters between 6mm – 8mm, the fixing has been further optimised in comparison to its predecessor. For instance, as an alternative to the screw-in depth of the screw thread, this screw-in depth can be applied without considering the length of the screw tip by calculation, but with a significantly increased pull-out parameter. This allows the pull-out load capacity or tensile strength to be increased by up to 60%.

A new feature of the PowerFull II is the screw geometry developed, which improves the pull-out load capacity, while the higher thread pitch reduces the screw-in torque for simple and easy installation. Its unique core-milling geometry enables low edge, axial spacing and high loads without any pre-drilling. The specially designed tip geometry makes it easy to place and insert while reducing the splitting behaviour in the base. Also, the needlepoint allows the screw to be placed and inserted with ease under extreme conditions such as slanted screw connections.

The PowerFull II version with a cylinder head is ideal for wood-on-wood connections. Additional mill pockets allow the head to be neatly countersunk deep into the wood using a long bit. A countersunk head variant is also available, with mill pockets below the head is ideal for fastening steel parts to wood, preventing fixtures from being damaged by reaming.
