Bolt Anchor AN BZ plus A4

Application

Anchor for push-through and mounting in M&E services and plant construction in concrete tensile zones. This anchor combines high admissible loads with little edge and centre distances.
Suitable for attaching pipelines, channels, brackets, etc. in closed room and outside section.

  • No special drill required. Bore dia. = thread size
  • Simple and quick mounting due to its push-through concept
  • Drive-in hammer zone for preventing any thread damage

Scope of delivery

Supplied with washer and hexagon nut.

Installation

1.
Drill bore hole according to the minimum bore hole depth perpendicularly to the surface.
2.
Remove dirt from the hole.
3.
Drive the anchor into concrete up to its embedment mark.
4.
Immediately resilient after tightening with the torque wrench Tinst indicated in the table below. Advices of the mounting instruction are to be respected!
