FISCHER 59050 Spacer screw ASL 4.5 x 60 electrolytically galvanised steel

With the Fischer 59050 asl spacing screw, you align wooden battens, framing, and window or door frames with pinpoint precision and zero tension against uneven walls. Thanks to the synchronized twin threads with identical pitch, your fixture stays securely at the exact required distance without being pulled tight against the base, completely eliminating the need for shims or wedges. To carry higher shear loads, simply drive the screw at an angle between 15° and 30°. The T25 drive ensures positive torque transfer without slipping during push-through installation into solid timber or into masonry with suitable plugs.

Product description

The spacing screw for flexible positioning and alignment of wooden fixtures

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.

• Exact mounting even with attachments mounted at an angle
• Simple stand-off installation with two threads with the same pitch
• Fixing in solid building materials with fischer expansion plug SX Plus and in hollow building materials with fischer universal plug UX
• Flexible usage in wooden materials and wooden panels, as well as in solid mineral building materials and hollow mineral building materials
• 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

Suitable for

• 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

Building materials

• Without plug: suitable for wooden materials and wooden panels
• With SX Plus or UX pluall concrete and masonry materials

Application
