" Convenient, Portable & Effective LOCTITE® 271™ is a red, low viscosity, methacrylate-based threadlocking adhesive with high strength. With steel fixture time of 10 min, brass 5 min and stainless steel 15 min. Can tolerate slight contaminations of industrial oils. Suitable for all metal fasteners. Breakaway torque on M10 bolts of 26 Nm. Fluoresces under UV light. Perfect for temperatures between -65°F - 360°F (-54°C - 182°C).

## Questions & Answers

**Q: Would this be 2 heavy for gun sight installation or just what i need?**
A: It might be to much for 271. It was designed for larger treads 3/8 + hold, and might make it impossible to remove at a latter time because of inability to apply enough heat and torque to remove from small treads like a scope mount. use Blue which is for small threads

**Q: Does this product require a primer?  The fourth picture on Amazon suggests it does but the instructions do not mention a primer.  Stainless + aluminum**
A: I didn't need to. I used it on steel threads. Didn't even clean them. Applied this product and assembled. Hardened in minutes. I waiyed 24hrs  before use just in case. Excellent product. I've used in the automobile repair industry for 30yrs.

**Q: Would this be appropriate for the locking nut on a sink faucet, that is always coming loose and making the faucet wobble?**
A: Oh god no! This is for applications of extreme vibration and areas that's could be extremely dangerous if a bolt or nut came loose. All you should need for you faucet is the blue loctite. After using the red, you would need some serious heat and a breaker bar to free that nut if you needed to replace that faucet in the future.

**Q: if it is opened/used, how long will it stay fresh/usable?**
A: Unopened/opened shelf life of Loctite 271 is two years from date of manufacture. Since exposure to oxygen is what keeps the liquid product stable, and it is packaged in a "breathable" plastic bottle, there is no change in shelf life once the product has been opened.
