Loctite 243 is long recognised as the industry's leading medium strength threadlocker. The product capabilities of Loctite 243 have been enhanced to offer improved high temperature performance and to cure through light oil contaminations, while maintaining a very reliable cure on passive metal surfaces. Replaces Loctite 242 and the current Loctite 243 formulations.

How To Use
Step 1: Safety Precautions
- Keep out of reach of children.
Step 2: Preparation
- Protect work area. Parts to be sealed must be clean and dry. Shake the product thoroughly before use. Note: To prevent the product from clogging in the nozzle, avoid touching the bottle tip to the metal surface.
Step 3: Application
- For Thru Holes: Apply several drops of the product onto the bolt at the nut engagement area.
- For Blind Holes: Apply several drops of the product down the internal threads to the bottom of the hole.
- For Sealing Applications: Apply a 360°bead of product to the leading threads of the male fitting, leaving the first thread free. Force the material into the threads to thoroughly fill the voids. For bigger threads and voids, adjust product amount accordingly and apply a 360°bead of product on the female threads also. Assemble parts and tighten as required. Sets in approximately 10 minutes and fully cures in 24 hours.
Step 4: Cleanup
- Clean adhesive residue immediately with a damp cloth. Cured product can be removed with a combination of soaking in methylene chloride and mechanical abrasion such as a wire brush.
- For disassembly, shear with standard hand tools and remove with methylene chloride. In rare instances where hand tools do not work because of excessive engagement length, apply localized heat to nut or bolt to approximately 250°C. Disassemble while hot.
