If you work on anything with screws or bolts that tend to vibrate loose, this Loctite Blue threadlocker is essential. This 6-pack gives you plenty for multiple projects. The medium strength formula is perfect for most applications - it keeps fasteners securely in place but still allows you to remove them with regular tools when needed. The stick form is actually really convenient - no messy liquids to drip everywhere, and it's easy to apply precisely where you need it. Each stick is 19 grams, which lasts quite a while since you only need a small amount per fastener. Great for automotive work, machinery, bicycles, or any equipment where vibration is an issue. Unlike the red version which is pretty much permanent, the blue gives you that security while still being serviceable. Having six sticks means you can keep one in your toolbox, one in the garage, and still have plenty left over. Definitely one of those products that solves a common frustration with loose bolts.
