I needed this because the screws on my computer had a nasty habit of getting loose and falling out. So far it has been incredibly useful in many other loose-screw related situation around the house, so I'd totally recommend this.

Hay aplicaciones que requieren, o al menos es muy recomendable, utilizar un fijador de rosca. Para eso está toda la línea de estos productos Loctite que resaltan por su calidad. Este producto lo utilizo al ensamblar piezas en mi moto, y va a ser igual de útil en el carro. Esto es dónde la vibración puede hacer que se afloje algo.

Affordable, and happy it came in a small size as I didn't need a lot. Seems to hold well, easy to use, and with the cap you can seal it right back up and use it for later. Will be buying more. Hope this helps!

Anything with the Loctite brand is going to be of quality. The threadlock works fine on steel and titanium bits and creates a strong bond to the pieces.

I started using Loctite products over 45 years ago and I learned how well it performed while assembling aluminum parts for instrumentation. I now use it on my guns as I assemble them to prevent parts from coming loose from shock and vibration. I just put together a new AR15 build and I used it all over the gun for the accessory parts. I installed a new Magpul MIAD pistol grip, a Magpul vertical rail grip, a tactical flashlight, a Magpul front and rear MBUS set of sights, a Vortex 3X flip up scope and a Daniels Defense Omega Free floating hand guard quad rail. All of the screws and Allen head screws had Loctite applied as I did the assembly. I even applied it to the mounting screws on the Aimpoint Pro red dot sight. I like the blue Loctite as it helps to hold the screws more securely in place and helps to prevent corrosion which is important on a rifle or gun. The blue formulation locks the parts in place but you can still take the gun apart when you need to. I recommend that you not use the red Loctite on gun assembly and it is very difficult to take apart as it has a much stronger holding power. This is a great product with a proven history of working in difficult applications. I rated it at 5 stars and I recommend it to you.
