How to use
LOCTITE® 246 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 7070 to degrease and clean surfaces prior to applying LOCTITE 246 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 7649 (see cure speed vs activator graph in the TDS).
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 7649 (see cure speed vs activator graph in the TDS).
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.
FAQ
Prevent vibration loosening, prevent leaks, protect threaded components from corrosion and increase the reliability of mechanical fasteners by using a LOCTITE® anaerobic threadlocking adhesive.
Once fully cured, LOCTITE® 246 threadlocker can withstand temperaturers from -65°F to 450°F.
Yes, LOCTITE® anaerobic adhesives and sealants become highly resistant thermoset polymers once cured, making them suitable for a vast number of applications. Consult our online product resources or contact our technical teams for further information.
Yes, these products are all anaerobic adhesives that will function in a similar way. Variations in the adhesive characteristics (viscosity, gap-fill, strength etc.) will make them better suited to certain applications. Consult the product technical data sheets and/or LOCTITE® representatives for further information.
