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 fingerprint, the perfect coupling between screw and insert allows for high safety during screwing and longer insertion life, this also allows the use of pulse screwdrivers Technical specifications: References: EAN: 4048962321517; Fischer code: 545248
