LOCTITE® 262 Red High-Strength Threadlocker

Red High-Strength Threadlocker LOCTITE 262 is a general-purpose, red, medium-to-high strength anaerobic threadlocking adhesive designed for the permanent locking and sealing of threaded metal fasteners up to 3/4" (M25) in size. Its thixotropic formula prevents liquid runoff after application, making it ideal for high-vibration applications such as heavy machinery, transmission shaft bolts, ring gears, and engine studs. Key Features & Benefits: Permanent Locking: Prevents loosening and leakage caused by severe shock, stress, and vibration. Thixotropic Formula: Controlled viscosity minimizes liquid migration after applying to metal threads. UV Fluorescent: Glows under UV light for easy application verification and quality control. Chemical & Oil Tolerant: Resists motor oils, fuels, brake fluids, and industrial solvents. Multi-Metal Compatibility: Effective on steel, stainless steel, brass, and plated metal components.
