Fully threaded structural and reinforcement wood screws with cylinder head and Torx socket Size: (6x160 mm), Packaging: (100 pcs) Model: WKFC Screws designed for structural connections and reinforcement of wooden elements. Full thread ensures optimal connection of the connected elements "without pulling". The cylinder head allows for quick and invisible countersinking of the screw into the fastened element. Key parameters Model : WKFC-06160-B-(100)OP Size: 6 x 160 mm Packaging: 100 pcs. Socket: TX-30 Material: electro-galvanized carbon steel Original Product from a Reputable Company KLIMAS Wkręt-Met ® Features and benefits 1. Cylindrical head with TX socket Allows for quick and invisible countersinkion of the screw in the fastened element. The TX socket guarantees optimal torque transfer. 2. Full thread Ensures optimal connection of the connected elements "without pulling" 3. Reaming cutter Reduces the torque required for screwdriving by widening the hole in the fastened element. 4. Wax coating Thanks to a special wax coating applied during the manufacturing process, the screwdriving torque is significantly reduced. 5. Double thread Additional threads on the tip facilitate screwdriving - they allow for faster "grip" of wood with less pressure. 6. Milling tip/ cutting notches Special milling tip shape, up to 20% less resistance when screwdriving, which extends the life of the battery and the tools themselves. Cutting notches on the thread cut the fibers of the wood structure during screwdriving. 7. High torque Enables screwdriving screws without pre-drilling in hard types of wood. Substrates Solid timber, Solid glued timber (CLT, KVH, BSH/GLT) Glued laminated timber (LVL) Examples of applications Reinforcement with screws in the ridge zone, protection against cracking of a beam with a notch, reinforcement at the support point, reinforcement by adding a second beam, strengthening a beam in a spot weakened by a hole, connecting two girders, connecting two beams that pass each other. These are only example applications. WKFC screws are used for structural connections and reinforcing wooden elements.

Certificate European Certificate ETA-18/0817 07/06/2023 - a guarantee of the highest quality. This European Standard specifies requirements and test methods for materials, geometry, strength, stiffness, and durability (i.e. corrosion protection) of fasteners used in load-bearing timber structures. The screws we offer are characterized by the highest quality and can be safely used in construction. We make every effort to ensure that the products supplied to our contractors are safe and adapted to specific tasks. Installation method The screws do not require pre-drilling. However, in the case of long screws, it is worth pre-drilling. This makes it easier to insert the screw when screwing in, reduces stress in the wood, allows you to screw closer to the edge of the beam, places less strain on the tool. Pre-drill using a smaller diameter screw; for 8 mm diameter screws, we recommend using a 5 mm diameter drill bit.
