Thread Locker: Anaerobic adhesive with medium resistance to disassembly. Ideal for locking and sealing threaded pins and nuts that are disassembled quite frequently. Suitable for screws up to M- 46. How to use: make sure that the parts to be locked are clean, dry and free of grease. Apply a small amount of the product, just at the beginning of the thread and then proceed to lock the part.
