Anchor support with metric thread AM
Application area
Anchor support with metric thread type AM is designed for fixing the roof, sides and soil of mine workings and mines. Anchoring of the anchor in the hole is carried out using ampoules based on polyester resins and / or mineral compositions. The use of metric threads on the anchor allows you to increase the bearing capacity of the anchor support by increasing the bearing capacity of the threaded connection.
Completeness
- a rod made of reinforcing steel of a periodic profile (AMP anchor) or a metal rod of circular cross-section (anchor K) with a metric thread applied to one end;
- the nut is spherical;
- support washer;
