ProTek R/C Blue Thread Locker is a medium thickness, medium strength formula that provides great resistance towards shocks and vibrations, yet still allows hardware to be removed and disassembled with hand tools. It is a must-have item for 1/8 scale use, 1/10 scale use and especially any vehicle or aircraft with a nitro engine. ProTek R/C Blue Thread Lock also helps to prevent rusting of threads. 

For use, simply apply the fluid to the threads of your non-plastic fastener or nut, and tighten. In the absence of air, the fluid will start to cure in about 10 minutes, with a finished full cure in about 24 hours.

Strength: Blue - Medium
Removable: Yes
Permanent Lock: No
Cure Time: Sets in 10 minutes; full cure in 24 hours

ProTek RC Blue Thread Lock (Medium) (0.34oz)
Great thread lock for all RC applications! The bottle is also really easy to use, and the cap has a nice grip to it, so you do not have to close it with both hands when working on a car. At a decent price too!

ProTek RC Blue Thread Lock (Medium) (0.34oz)
It’s a translucent blue gel/liquid that creates a very strong hold, more than enough to endure 1/8 nitro applications. Works great, great price!
