This is a must have to secure bolts in place. It may seem like small quantity for the price, but it goes a long way. Just use a little, don’t put too much. Dry time is fast. I use it on my motorcycles, most recently on a sprocket bolt. Ride with confidence. Highly recommend.

’ve used Loctite Blue 242 on everything from motorcycle parts to furniture, and it works exactly as advertised. It keeps screws and bolts from vibrating loose, especially on items that see a lot of movement or stress. What I really appreciate is that it’s strong enough to hold, but not so permanent that you can’t remove the fastener later if needed.
The application is easy — just a drop on clean threads before tightening, and you’re good to go. It sets up nicely and doesn’t make a mess. I’ve had zero issues with rust or corrosion after use, and the bottle has lasted me a long time.
Definitely recommend this for anyone who works on machines, tools, or even around the house. Just be sure you’re using it on parts you might want to remove later — this isn’t the red (permanent) stuff!

I purchased this Loctite primarily to secure the optic on my home defense firearm, and it has performed flawlessly. After multiple range sessions and hundreds of rounds fired, my optic hasn’t shown even the slightest bit of movement – exactly what I needed for a critical application where reliability is paramount.
The product proved so effective that I started using it for household repairs too. Those annoying, constantly-loosening ceiling fan screws that created a shaky noise? Completely silenced after application. The medium-strength formula seems perfect – strong enough to keep things secure, but still allows for disassembly when needed with standard tools.
Application was simple with the precise nozzle, and a little goes a long way. I appreciate that it dries clear and doesn’t leave messy residue. For anyone needing to secure screws in firearms, machinery, or household items, this Loctite delivers professional-grade results.
For those using it for firearm related screws: Always follow manufacturer instructions for firearm applications and allow proper cure time before use.

This threadlocker works exactly as it should. I’ve used it on everything from tools to automotive parts, and once it cures, bolts stay secure with no loosening from vibration or use.
It’s easy to apply, sets up quickly, and gives peace of mind that everything will stay tight over time. Whether for small screws or larger fasteners, it performs great every time.
Reliable, strong, and a must-have in any toolbox. Highly recommend!

Strong hold, yet removable when needed
I’ve used Loctite Threadlocker Blue 242 on everything from automotive bolts to small machine screws, and it’s one of those products you end up reaching for more often than expected. It provides a nice middle ground: strong enough to keep fasteners from loosening due to vibration or everyday use, but still removable with standard hand tools when you need to take something apart later. I recently used it on a set of bolts for an outdoor project, and even after weeks of exposure, they stayed tight with no signs of backing out.
The consistency is easy to work with—just a drop on the threads goes a long way. The small 6 ml tube is convenient for keeping in a toolbox or glove compartment, and it dispenses cleanly without making a mess. It also helps prevent rust and corrosion on the threads, which is a nice bonus if you’re working on vehicles or equipment exposed to the elements.
A couple of things to keep in mind: this is a medium-strength formula, so it’s not for heavy-duty applications where you need a permanent lock (for that, you’d want Loctite Red). Also, it takes a little time to fully cure, so give it that window before putting things under full load.
Bottom line: A reliable, easy-to-use threadlocker that’s perfect for everyday maintenance and repairs, offering strong but removable security for nuts, bolts, and screws.

Gotta love threadlocker! This is a great product that I’ve used extensively (in conjunction with locking nuts) when mounting d panel jacks in audio racks. I can break the screws loose easily enough if I need to replace the jack, but it keeps the screws perfectly in place otherwise.
