Our glue in bolt stainless steel is a high-quality product from Climbing Technology. The hook is made of highly corrosion-resistant AISI 316L (A4) stainless steel. It is also known as a “stainless steel composite hook”.
This hook has some great features. Firstly, its high steel quality. Secondly, it has the EN 959 standard. This means that it can be used by all climbing crag holders. For example, for climbing area rebolting. Thirdly, the glue in bolt stainless steel is available with two shaft lengths. On the one hand with 7.5cm. And the other with 10cm. This allows you to react perfectly to different rock qualities.
Fourthly, this glue in bolt has NO load-bearing weld seam. Fifthly, the stainless steel composite hook has a perfectly sized carabiner eye. It fits two carabiners as well as one carabiner and one rope.
In short. If you’re looking for a high-quality glue in bolt with EN 959 standard for public climbing areas, you’ve come to the right place!

Stainless steel = AISI 316L
This glue in bolt stainless steel is made of high-quality AISI 316L steel. The German standard refers to this steel quality as A4 steel. This means that it has a high chromium content, which ensures the formation of a corrosion protection layer.
Not familiar with all this? Then read our article“Steel quality at expansion bolt and glue in bolt“. We explain all this in great detail there. You will then be able to judge the quality of this stainless steel composite hook much better!
No load-bearing weld seam!
This stainless steel composite hook has no load-bearing weld seam.
In other words, it is one of the strongest and safest on the market. This is because the 8 mm steel wire of this glue in bolt stainless steel is actually bent “twice”. It is fixed to the shaft with a mini welding spot. But only so that the two ends do not diverge.
By “pressing” the shaft, the final result is its 12mm diameter.
glue in bolt Stainless steel – Installation
As with all glue in bolt, installation is a complex process. Only those who work conscientiously and accurately will obtain reliable fixed points. But what does this mean in practice?
We explain this in detail in our article “Settingglue in bolt “.
A short version looks like this. Firstly, you have to drill deep enough. Secondly, clean the drilling hole extremely clean. Thirdly, attach the channel for the carabiner eyelet on the side of the rock. And fourthly, glue the stainless steel composite hook cleanly in place.

By the way, we recommend doing this only with injection mortar to do this.
Glass mortar cartridges are only suitable for individual fixed points or for very experienced developers.

These glue in bolt consist of an austenitic steel with a chromium content (mass fraction) of at least 10.5%. This is why this steel is also referred to as “chromium steel” or “stainless steel”. Depending on the amount of chromium, these steels are divided into categories such as A2 steel or A4 steel.
This type of hook is best installed with injection mortar. This requires a suitably sized hole and extremely clean hole cleaning. A channel must also be drilled for the hook eye on the side of the rock. Fill the hole with sufficient mortar and then insert the glue in bolt while turning. The excess adhesive is neatly spread around the hook eye.
Anyone setting up a public climbing area should only use glue in bolt with the EN 959 – UIAA 123 standard!
