Available sizes:
LOCTITE 243 is a medium strength blue threadlocking adhesive that seals and secures metal nuts and bolts to prevent loosening due to shock and vibration.
LOCTITE® 243 is a general purpose threadlocker that provides a medium strength bond. LOCTITE 243 works on all metals, including passive substrates such as stainless steel, aluminum and plated surfaces. It is proven to be tolerant of minor contamination due to industrial oils, e.g., motor oils, corrosion prevention oils and cutting fluid.
- Prevents loosening on vibrating assemblies, e.g. pumps, gear boxes or presses
- Works on all metals, including passive substrates (e.g. stainless steel, aluminum, plated surfaces)
- Proven to tolerate minor contamination by industrial oils, e.g. motor oils, corrosion prevention oils and cutting fluids
- Permits disassembly with ordinary hand tools for easy service and maintenance
- P1 NSF Reg. No.: 123000

How to
Step by Step Guide
1. Preparation - Cleaning
It is recommended to use LOCTITE® SF 7063, SF 7064, or SF 7070 to degrease and clean surfaces prior to applying threadlocker adhesive.
2. Preparation - Activation
If cure speed is too slow due to passive metals (stainless steel, aluminum and plated metals) or low temperature (below 5°C), use activator LOCTITE® SF 7240 or LOCTITE® SF 7649 (see cure speed vs activator graph in the TDS).
3. Application
Apply liquid threadlocker to the engagement area. For manual dispensing, the use of a peristaltic handgun or the LOCTITE® Pro Pump is recommended to ensure a consistent application volume.
4. Application - Through Hole
Insert bolt and apply threadlocker to the exposed thread. Assemble nut and tighten to the correct/specified torque.
5. Application - Blind Hole
6. Assembly
Assemble and tighten. If several bolts are being assembled, torque them down to the correct value within the fixture.
7. Disassembly - Hand Tools
Disassemble with standard hand tools.
Hint
For the disassembly of corroded or seized parts use LOCTITE® LB 8040 Freeze and Release.
