Loctite 271 Red Threadlocker, 36 ml bottle, part number 492142, is a high-strength adhesive designed to permanently lock and seal fasteners against loosening from vibration and shock. As a trusted Loctite product, this heavy-duty threadlocker delivers reliable retention for critical automotive assemblies, offering a durable bond that resists tampering and coolant exposure. Suitable for OE and aftermarket applications, it provides a robust solution where disassembly is only achievable with heat.

Use cases: securing studs, bolts, and flanged connections in engines, transmissions, and suspensions where movement would otherwise loosen fittings. Common failure symptoms include recurring loosened fasteners, increased clunking, or leaks around joints; replace when you notice repeated thread movement or after servicing moving parts. This product is ideal for select European vehicles.
