The fischer Hammerfix N-P K with mushroom head consists of a plug and a nail screw made of high-quality nylon. 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 N-P K is ideal for fixing of thin components and in the viewing area. The N-P K is completely made of plastic, conducts no electricity and thus is ideal for electrical installations.
