Power-Fast FPF-ST ZPP; fPF-ST ZPP; support material: steel; coating: white galvanised; fingerprint: TORX TX star imprint; thread: partial thread; head shape: countersunk head; advantages: Special tip geometry: The special thread up to the tip ensures an extremely fast grip and avoids the swings of the screw already in its placement; thread with Sharp milling: The sharp mills in the first third of the thread in combination with the high-performance lubricant of the Power-Fast screw effectively reduce friction allowing for quick screwing; double thread: the front double thread inhibits the formation of cracks in the wood; simultaneously the double central thread allows the screw to feed without resistance so you can perform the installation near the edges without a pre-hole; milling ribs on the stem: The double slope cone with reinforced connection function between the stem and the head prevents the detachment of the screw head - especially with hard woods or in the application of steel elements. Anti-underhead allow easy sinking of the head and at the same time a perfect thread attachment; extra deep imprint: The extra deep impression allows a secure grip of the screwdriver on the Torx imprint; the perfect coupling between screw and insert allows for high safety while screwing and a longer life of the insert; this also allows the use of pulse screwdrivers Technical specifications: References: EAN: 4048962321388; Fischer code: 545235
