Description
Overview:
LOCTITE 243 Blue Medium Strength Threadlocker 24ml is a professional-grade, medium-strength anaerobic adhesive for securing and sealing metal threaded fasteners. Supplied in a 24 ml bottle, it is based on methacrylate chemistry that cures in the absence of air between close-fitting metal surfaces. It helps prevent loosening from vibration and shock, while sealing threads against fluid leaks and moisture ingress to reduce corrosion. Ideal for bolts, screws, studs, and threaded plugs on construction equipment, garden machinery, vehicles, power tools, and general industrial assemblies. The blue colour helps identification during maintenance, and the strength level allows later disassembly with standard hand tools when required. Manufacturer Part Number (MPN): 865 605. Trusted for routine servicing, repairs, and new builds where reliable, clean, and consistent thread locking is needed.
Key Features:
- Medium-strength hold for security in service yet removable with normal hand tools
- Resists vibration and shock to keep fasteners tight over time
- Seals threads to help prevent fluid seepage and air leaks
- Helps protect against corrosion by excluding moisture and contaminants
- Oil-tolerant formulation for reliable performance on as-assembled components
- Suitable for most metal fasteners including steel, stainless steel, and plated parts
- Thixotropic consistency helps prevent run-off and migration after application
- Working temperature range suited to typical machinery and automotive environments
- Supports clean, precise application; 24 ml pack is convenient for workshop or site use
- Reduces the need for lock washers and split pins in many assemblies
Typical Applications:
Used on cover screws, pump and motor housings, pulleys, engine casings, gearbox and PTO fixings, guards, brackets, handle and frame bolts, threaded plugs and sensors. Suitable for construction plant, agricultural and garden machinery, automotive repair, power tools, compressors, and general MRO tasks where fasteners are exposed to vibration, thermal cycling, or fluids.
