# Category: Technical chemicals - [An even more powerful bond with INDEX® chemical anchors](https://menet-trend.hu/en/nonox-world/an-even-more-powerful-bond-with-index-chemical-anchors.md) — With a chemical anchor the resin bonds the base material and the fixing element along the entire hole: no expansion force, no cracking, and an even load distribution that works close to edges too. The polyester MO-PU Universal covers general fixings, while the MO-V Vinyl Ester takes on structural loads. - [Lock your screw joints with LOCTITE threadlockers!](https://menet-trend.hu/en/nonox-world/lock-your-screw-joints-with-loctite-threadlockers.md) — Two outstanding threadlockers that keep screw joints in place under the toughest conditions: LOCTITE 270 for high-strength, vibration-proof locking, and LOCTITE 243 as the versatile, medium-strength choice. Both cure on passive surfaces such as stainless steel and aluminium, and tolerate lightly contaminated surfaces. Suitable for NONOX screws too. - [Concrete adhesives](https://menet-trend.hu/en/nonox-world/concrete-adhesives.md) — P-NEX is polyester-based, V-NEX is vinyl ester-based, and both bond into solid building materials with no wall plug at all. The six-step method, plus a comparison table covering cracked and wet concrete, hollow brick, underwater use and seismic compliance. - [OKS-250 anti-galling paste](https://menet-trend.hu/en/nonox-world/oks-250-anti-galling-paste.md) — Galling is not a material defect and not corrosion – but with stainless threads it can happen on the very first tightening. What causes it, how to prevent it with heterogeneous A2/A4 pairings, slower tightening and clean threads, and what OKS 250 anti-galling paste does. Plus our anti-galling warranty. --- HTML:
