Spacing screw ASL

The fischer spacing screw ASL is a special screw made from zinc-plated steel with two threads with perfectly tailored pitches. The spacing screw is ideal for positioning and adjusting components without plugs in wood and wooden materials, door and window frames, claddings and substructures made of wood and for securing components without pulling them against the substrate. The special screw is used in a push-through installation process. When the screw is screwed in, the outer thread cuts into the pre-drilled fixture, securing it into position. In conjunction with the fischer expansion plug SX Plus, the ASL is used in concrete and, together with the fischer universal plug UX, in masonry.
