Fixings & Fastenings
Bolt Screw Anchor MMS-PR
Group: 1405
Application
Suitable for quick and safe installing of channel 27 to concrete ceilings or walls and masonry constructions (of calcareous sandstone, solid bricks, clinker bricks, natural stone). To be applied in closed rooms - not suitable for damp locations.
The nail head diameter is adapted exactly to the hole and hole pattern of the channels 27.
- Easy drilling (6 mm only), no special drill required.
- Small distances due to low expansion pressure.
- Excellent transmission of the torque due to Torx connection.
Assembly
An impact screwdriver is best suitable for mounting, using a T30 Torx bit. For subsequently adjusting the component to be connected, unscrew the Bolt Screw Anchor a few millimetres and tighten it again afterwards.
