- Product description
Features and benefits:
Loctite 221 is low-strength - it secures the thread, but can be removed manually at any time after curing. Loctite 221 low-strength threadlocker is therefore suitable for threads that are handled frequently, e.g. due to revisions of machine parts and the like. After application, Loctite 221 hardens in the joint without access to air. Use Loctite 221 to secure grub screws, rather small threads, etc. The temperature resistance up to 150 °C is an advantage.
