Anaerobic threadlocking adhesives are specially developed for securing metal threaded joints against self-loosening. They work on the principle of curing in the absence of air – after being applied to the thread and tightening the parts, the adhesive cures and creates a strong, durable and leak-tight joint. This technology is commonly used in the automotive, mechanical engineering, electrotechnical and maintenance industries, where reliability under long-term load is essential.

Anaerobic adhesives create a permanent barrier between threaded components, preventing their loosening due to vibration, impact or temperature changes. At the same time, they seal threads against leakage of liquids, oils and gases and protect them against corrosion. Once cured, they withstand temperatures up to +150 °C (even higher for special grades) and provide long-term stable mechanical strength.
The range includes low-, medium- and high-strength anaerobic adhesives, which differ according to the required joint strength:
Low strength – for small screws and joints that are frequently disassembled (e.g. electronics, fine mechanics).
Medium strength – universal use for standard screws, nuts and threads in industry and service.
High strength – for permanent joints that are disassembled only with heat or special tools (e.g. bearings, shafts, gear assemblies).
Thanks to this variability, it is easy to choose the right type of adhesive for the specific application – from minor repairs to structural joints subjected to high loads.
The use of anaerobic adhesives is very simple – just apply a few drops into the thread and, after assembly, the joint locks itself. The adhesive does not cure outside the joint (in the presence of air), so there is no contamination of the surrounding area. After curing, the joint remains strong, leak-tight and resistant to vibration and chemicals.
The Anaerobic Adhesives (Threadlocking) category represents a professional, safe and efficient solution for securing screw and threaded joints in all branches of industry. It offers reliability, easy application and long service life, making it an ideal choice for anyone who requires stable and permanently strong joints without the risk of loosening.
