Loctite 268 Threadlocker - High Strength
Available
The Loctite 268 High Strength Threadlocker Stick is a red, wax-like semi-solid threadlocker for permanently locking and sealing studs, nuts and bolts against vibration. With 40 N·m breakloose torque on M10 steel, it is intended for fasteners that should stay put. The no-drip stick suits overhead and vertical work, fixtures in about 5 minutes and handles -55°C to +150°C. This is the 19 g stick.
After cleaning the threads with a Loctite solvent, wind out a small amount, remove any skin and fill the threads where the nut will engage, then assemble as normal. Removal needs local heat to about 250°C with the parts taken apart while hot, and it is not normally recommended for plastics, particularly thermoplastics, or for oxygen-rich systems. Consult the Safety Data Sheet before use.
