Flugel Self-Drilling Screw
FLOK supplies Flugel self-drilling screws with wings for joining wood, plywood and chipboard to metal up to 4 mm. Certified fasteners in stock.
The Flugel self-drilling screw (German Flügel — “wing”) takes its name from a design feature: the drilling tip has two wing-shaped projections. When joining a wooden part to a metal part, the screw first drills a clearance hole, and when it reaches the metal, the wings break off.
The screw shank has ribs that act as cutters and perform countersinking (machining the pilot hole). In a single pass, the screw drills through the parts being joined, countersinks the hole and draws the parts together.
It is used in furniture manufacturing and anywhere a seat needs to be prepared for installing fastening bolts, rivets or screws. It is used to join plywood, wood and chipboard to metal bases up to 4 mm thick.
It is made of carbon steel with a coating — electrogalvanizing, yellow passivation and other methods. The coating extends the service life of the fastener and preserves the initial clamping force of the joined surfaces. The screws are resistant to moisture and aggressive operating conditions.
The Flugel screw is in stock at FLOK. The fasteners are certified, and customers receive the relevant documentation upon purchase.
