The fischer Hammerfix N-P with mushroom head consists of a high-quality nylon plug and a nail screw made from zinc-plated steel and stainless steel. These are pre-mounted for a fast installation process. The Hammerfix is inserted through the attachment part in a time-saving push-through installation. When the nail screw is hammered in, the plug sleeve expands and creates a secure anchoring in the building material. The fischer Hammerfix N-P with mushroom head is ideal for the fixing of thin attachment parts and attachment parts with slots, particularly in visible areas.
