The Raumer Antrax glue in bolt is a small, lightweight glue in bolt. It is very suitable for alpine terrain. Firstly, it is very light. It weighs just 75 grams. Secondly, you only need a 10mm hole if you are working with a injection mortar when working with one. The manufacturer is Raumer Climbing in Italy.

Countersink and glue the carabiner eyelet!
One of the most common mistakes when processing the Raumer glue in bolt Antrax is the following: the carabiner eye of the hook is not countersunk or not glued. Hence our advice. Firstly, drill out a small channel from drilling hole vertically downwards. Clean this. After inserting the hook, spread the adhesive that oozes out properly. This protects the hook much better, especially against radial forces!
Borehole cleaning Raumer glue in bolt Antrax
If you want to bolt a climbing route with a bolt, you should proceed carefully. This is because setting up a climbing route with glue in bolt harbors several potential sources of error.
Firstly, start with a high-quality SDS drill bit to obtain a round drilling hole. For example, the Fischer Quattric or Pointer Plus. This is the only way to achieve an even contact with the injection mortar.
Secondly, the borehole cleaning process is extremely precise. Firstly, the drilling dust with the drilling hole blow out pumb blown out. Secondly, two more cleaning passes with the hole brush or Fischer brush. Thirdly, blow out again and that’s it!
Use of glass mortar cartridge
Installing this glue in bolt with a glass mortar cartridge is not ideal. You can use a 10 mm hole or an RM 10 cartridge. However, this can lead to problems with limestone or porous rock.
This is because many small pores can soak up the liquid adhesive. On the one hand, the mortar then remains extremely dry and makes it difficult to hammer in the hook. On the other hand, the adhesive may not have the correct mixing ratio.
Our tip: Rinse the Bohroch with water after cleaning!
Installation with injection mortar from a cartridge is much better and easier.
A veriable alternative is to use the Fischer FHB II-P 10 x 75mm glass mortar cartridge.
Galvanic corrosion
Galvanic corrosion can also occur with the Raumer Antrax glue in bolt. Therefore, never use a zinc plated screw link – quick link. As this is a “poorer” metal, it will inevitably break down over time. If a quick link is to be permanently installed, it must be made of A4 steel.
Bolting near the sea
The Raumer glue in bolt Antrax cannot be used near the sea. For this we clearly recommend the products from Fixe Climbing. Because the Fixe PLX – Duplex steel products are made of the right steel.
