The fischer Hammerfix N-S with countersunk head consists of a high-quality nylon plug and a zinc-plated nail screw. These are already pre-fitted for quick assembly. The Hammerfix is led through the component in the time-saving through-type installation. When driving in the nail screw, the fixing sleeve expands and anchors itself securely in the building material. The fischer Hammerfix N-S with countersunk head is ideal for fixing timber constructions in all building materials in internal areas. Features: The rapid hammerset installation reduces the amount of time required and allows for an economic series installation. The integrated hammer-in stop prevents the plug from expanding prematurely (jamming), thus enabling a problem-free installation.
