There are lots of variety's of Loctite from low strength to high strength. I would NOT recommend High Strength Loctite for your use case. Loctite is like Kleenex and within in the brand it goes like the following: Low Strength PURPLE 222 Removable BLUE 242 High Strength RED 271 Other brands of thread locker may have different colors. Use Cases: I use Purple at work, typically in very light duty steel to plastic joints that are regularly serviced. I use Blue in several locations on my car/motorcycle/bike including rear suspension bolts (when I had a FS). These were all Stainless Steel bolts into Stainless Steel Nuts or Aluminum Castings. I don't have experience using it on composites unless it was into a metal threaded sleeve. I use red on things I don't ever plan on taking apart. The label on Red says "Must be heated to 500°F to separate parts"
