Review on 🔒 Loctite 271 Threadlocker for Automotive: High-Strength, High-Temperature, Fluorescent, Anaerobic Red - 36mL Bottle (Part Number: 37479-492142) by Sean Ceo

Make sure you know the color code. I needed something more durable than blue Loctite, even when exposed to oil and solvents, red Loctite will not slip. Red Screw Lock 271 (only for the automotive aftermarket) is a high-strength, hard-wearing screw lock. Particularly suitable for permanently fixing bolts and press fits. Adds 3000 psi holding power in slide and press fit assemblies. *If you ever want to unscrew something you used red on, use blue.
