Arexons 52A43: The Safety of Locking, the Freedom of Maintenance
In mechanics, vibration is the silent enemy. Whether it's a motorcycle engine or an industrial component, accidental unscrewing can cause structural damage or safety hazards. Arexons System 52A43 Medium Threadlocker (code 4704) is the "smart" solution: it offers a strong hold against mechanical shock, yet is formulated to be removed with common workshop tools without the risk of breaking the screw or having to resort to extreme heat.
Why buy Arexons Medium Threadlocker instead of a Strong Threadlocker?
Choosing the "Medium" grade (identified by the product's blue color) is essential for all components requiring periodic inspection or replacement. Compared to permanent retainers, the 52A43 offers:
- Easy Disassembly: All you need is a wrench or screwdriver to overcome the breaking torque, ideal for oil caps, crankcase bolts and adjusting screws.
- Chemical Sealing: In addition to locking, it acts as a sealant preventing fluid leaks through the threads.
- Thermal Resistance: Maintains performance from -55°C to +150°C, covering the vast majority of automotive and domestic applications.
- Time Saving: Prevents the need to continually re-tighten vibration-prone bolts.
Technical Specifications
The product is a blue anaerobic adhesive. Its medium viscosity makes it easy to apply without excessive runoff. The maximum allowable diametrical play is 0.25 mm, making it suitable even for imperfect threads.
How to use
- Thoroughly clean and degrease the metal parts (screw and threaded hole) to remove any oil or grease residue.
- Apply a few drops of Arexons 52A43 to the tip of the screw or along the thread.
- Assemble and tighten the components to the required torque.
- The product hardens in a few minutes (functional fixing in 1-3 hours), while total catalyzation occurs in 24 hours.
Frequently Asked Questions
How do I distinguish medium threadlocker from strong threadlocker?
The Arexons System range uses a standard color code: the MEDIUM threadlocker (52A43) is blue, while the STRONG threadlocker (52A70) is green. Blue indicates that it can be unscrewed with normal hand tools.
Can I use it on plastic bolts?
No, anaerobic threadlockers only react with metal surfaces. For plastics, polymer-specific adhesives or threadlockers are required, as anaerobic products may cause stress cracking in some plastics.
What happens if I put too much product?
The threadlocker only hardens inside the thread (where there is no air). Any excess product that leaks out will remain liquid and can be easily removed with a clean cloth.
