About this part

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.

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!

Low cost and good quality. Holds bolts from slipping out while driving, releases them when you turn a wrench

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!

All eleven reviews are five-star ratings from verified owners of the medium-strength 0.5 fl.oz bottle.

Price and bottle size are frequently praised, and reviewers mention easy-to-use packaging with a grippy cap. No recurring problems or negative experiences are reported, though several reviews are brief and general, and long-term durability is not addressed.
