Loxeal 83-55 high-strength anaerobic threadlocker 50 ml, medium-size metal thread locking adhesive for maximum load and corrosion protection

Loxeal 83-55 high-strength anaerobic threadlocker 50 ml is a single-component compound designed to secure medium-size metal threads against self-loosening, unscrewing, leakage and corrosion. It cures in the absence of air within the gap between two metal surfaces, forming an elastic, leak-tight bond resistant to vibration and load. It can also be used on less active, slightly oily metal surfaces. :contentReference[oaicite:6]{index=6}

Advantages and unique features

• High-strength anaerobic threadlocker for medium-size threads – reliable retention in highly loaded joints.
• Replaces mechanical locking devices such as spring washers, tab washers and locknuts.
• Resistant to gas, air, water, oils, alkalis and many other process chemicals.
• High resistance to shock and vibration – maintains maximum stress in the threaded joint.
• Provides 100% protection against corrosion and excellent sealing of threaded connections.
• Fluorescent additive allows easy inspection of adhesive presence in the thread under UV light.
• Can be used on less active, slightly oily metal surfaces.

Properties and applications

• Securing medium-size threads: bolts, studs and nuts in drive systems, structural components and industrial machinery.
• Maximum thread loading: particularly recommended for stud bolts in flange connections and other highly stressed joints.
• Sealing of threaded joints: complete filling of the threads ensures leak-tight connections carrying liquids or gases.
• Resistance to vibration and temperature changes: maintains mechanical properties over a wide service temperature range from -55 to +150 °C.
• Replacement of additional hardware: eliminates the need for spring washers, lock washers and other mechanical locking elements.
• Limitations of use: not recommended for equipment with pure oxygen or chlorine, or in contact with thermoplastic materials where stress cracking may occur. :contentReference[oaicite:7]{index=7}

After use, clean the bottle neck and close it immediately. Keep away from foodstuffs and out of the reach of children. :contentReference[oaicite:8]{index=8}

FAQ

What is Loxeal 83-55 used for?
Loxeal 83-55 is a high-strength anaerobic threadlocker for securing medium-size metal threads in metal-to-metal joints against loosening, unscrewing, leakage and corrosion, especially in drive systems, structural components and flange connections.

Can Loxeal 83-55 be used on slightly oily surfaces?
Yes, it can be applied to less active, slightly oily metal surfaces, although for maximum strength thorough cleaning and degreasing of the threads is recommended.

How fast does the adhesive cure?
Typical fixture time is 10–20 minutes, functional strength is reached after 1–3 hours and full cure after approximately 3–10 hours at room temperature.

What thread sizes can be locked?
The product is suitable for threads up to about M20 and gaps up to 0.15 mm.

Can joints bonded with Loxeal 83-55 be disassembled?
Yes, but due to the high strength of the adhesive, disassembly is more difficult and usually requires appropriate tools and, if necessary, heating of the parts while observing safety procedures.
