The spacing screw with inner TX drive and parallel thread
Advantages

• The coordinated threads with the same pitch allow for the pin-point positioning and alignment of the fixture, which can even be mounted at an angle to the screw. This allows for an exact and flexible fixing.
• During the installation, the fixture is not pulled onto the substrate, instead it is brought directly to the desired distance and position. This allows for a simple and exact installation.
• When combined with SX Plus 8 and UX 8 plugs, it can be used in almost all wall materials, guaranteeing a secure fixing.

The fischer spacing screw ASL is a special screw made of zinc-plated steel with two coordinated threads at the same pitch, allowing for precise and time-saving stand-off installation. The special screw is used in through-type installation. When driving in the screw, the external thread cuts into the pre-drilled fixture, and fixes it. If the screw is driven in at an angle of 15 - 30° then higher shear loads can be carried. The fischer spacing screw ASL is ideal for fixing timber window and door frames, cladding, and sub-constructions without plugs in wood and wood materials.

Functionality

• The ASL is suitable for push-through installation.
• Pre-drill the fixture at the desired angle in order to achieve the correct positioning and alignment.
• When screwing in the screw, the external thread cuts into the pre-drilled fixture, and fixes it into the stipulated position.
• The angled position of the screws (15° - 30°) allows high shear loads to be supported.
