Loctite 262 red medium to strong 50 ml

LOCTITE 262 – Threadlocker

LOCTITE 262 is an anaerobic, reddish threadlocking adhesive based on acrylic technology (dimethacrylate ester). The product is designed to lock and seal threaded connections by curing when confined in the absence of air between close-fitting metal surfaces. LOCTITE 262 fluoresces under UV light, which can be used for quality control, and has a fixture time on steel of approximately 10 minutes.

What it does

The threadlocker prevents loosening and leakage caused by heavy shock and vibration by permanently locking and sealing threads. The product's thixotropic viscosity reduces migration after application, and the anaerobic curing process is activated when the material is confined between metal surfaces.

Application and handling

The description and manufacturer's instructions indicate the following practical steps and recommendations for assembly:

• Clean all surfaces (internal and external) with a suitable cleaner and allow them to dry.
• If the substrate is inactive or the cure speed is too slow, the use of recommended activators on threads before application is advised.
• Shake the product thoroughly before use and avoid the tip touching metal during application to prevent clogging.
• For through-holes: apply several drops to the bolt at the nut engagement area. For blind holes: apply drops to the bottom third of the internal threads or the bottom of the hole.
• For sealing: apply a 360° bead to the leading threads, leaving the first thread free. Press the material into the threads to fill voids, then assemble/tighten.
• For disassembly: local heating of the connection to approx. 250 °C is recommended, after which disassembly should be carried out while the component is hot.

Typical applications

LOCTITE 262 is indicated for permanent locking and sealing of threaded connections and explicitly mentions application on large bolts and studs up to M25, as well as preventing loosening and leakage due to shock and vibration. See manufacturer's datasheet
