How to
Step by Step Guide
1. Preparation - Cleaning
LOCTITE 268 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 268 threadlocker.
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 LOCTITE® SF 7649 activator. Allow to dry.
3a. Application - Through Hole
Apply a 360 degree band of threadlocker to the male fastener at the area of engagement and completely fill the thread roots - generally the width of 2-3 threads. Assemble nut and tighten to proper torque.
3b. Application - Blind Hole
Apply threadlocker to entire diameter of thread engagement area on male fastener, install fastener into blind hole, and tighten to proper torque.
4. Assembly
Assemble and tighten to proper torque requirement. If several bolts are being assembled, torque them down to the correct value within the fixture time window.
5. Disassembly
Disassemble with standard hand tools. If not possible, apply localized heat to approximately 500°F/260°C and disassemble while hot.
