The impressive performance of the WF partial threaded fasteners
WFD, WFO, WFR: timber construction screws for timber to timber and timber to steel connections
The WFD timber construction screw with dual drive
n Combined internal and external drives T30/H12 – T40/H15n internal drive for countersinkingn no danger of skidding with the external hexagon driven washers available to increase pull- through capacity of the head
Advantages:n knurl reduces the insertion torque, making the fasteners particularly easy to use.
n European Technical Approval ETA-12/0373
The WFO timber construction screw with internal drive
n T40 – T50 internal drives n rapid insertion thanks to the coarse threadn flat head increases pull-through capacity of the head
The double-start threaded WFR for rapid installation
n T20 – T30 internal driven 50% faster insertion thanks to the double-start threadn countersunk head n bites with minimal pressure n milling recess prevents splitting of the wood
tions such as fitting rafters, roofing and timber house construction. Smaller WFR’s are useful for fixing wood-based panels to sub-frames; e.g. shear walls. Various applications can be realised
The self-tapping timber screws WFD, WFO and WFR can be used to fix tim-ber members, wood-pased panels and steel parts to timber. WFD and WFO are primarily used in timber construc-
with the comprehensive range of WF system. The European Technical Ap-proval enables a reliable design.
