Main features
- Low-Migration Thixotropic Application
- Easy Hand-Tool Disassembly
- Small-Fastener Threadlocking Control
Product Description
LOCTITE 222MS is a purple, low-strength thixotropic anaerobic threadlocker for metal fasteners that require easy disassembly with standard hand tools. The one-component liquid cures when confined between close-fitting metal threads and does not require mixing before use. Its thixotropic flow helps reduce migration after application, making it useful for adjustment screws, small-diameter fasteners, and long threaded engagement. LOCTITE 222MS also fluoresces under UV light for application inspection. Torque ranges are specific to steel, cadmium-plated, and zinc-plated fastener configurations, with cure performance dependent on substrate, temperature, and joint conditions.
Key features
- Low-migration flow: Thixotropic behavior helps the liquid remain at the applied thread area.
- Easy disassembly: Low cured strength supports removal with standard hand tools.
- Small-fastener control: The formulation is suited to adjustment screws and long-engagement fasteners.
Applications / Suitable for
- Adjustment and set screws
- Small-diameter metal fasteners
- Long-engagement fasteners requiring hand-tool disassembly
