LOCTITE® 243 is suitable for use on most "as-received" fasteners with light coatings of corrosion prevention oils without cleaning. However, for heavily oiled or contaminated fasteners, it is recommended to use LOCTITE® SF 7063, SF 7064, or SF 7070 to degrease and clean surfaces prior to applying LOCTITE 243 threadlocker.
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).
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.
Insert bolt and apply threadlocker to the exposed thread. Assemble nut and tighten to the correct/specified torque.
Apply several drops of liquid threadlocker down the sides of the blind hole filling the lower third. Apply several drops to the bolt.
Assemble and tighten. If several bolts are being assembled, torque them down to the correct value within the fixture.
Disassemble with standard hand tools.
For the disassembly of corroded or seized parts use LOCTITE® LB 8040 Freeze and Release.
