THREAD LOCKER, TO STRENGTHEN AND SEAL YOUR THREADS
 

Thread locker is an adhesive product used to hold and seal all types of threads: screws, nuts, studs, etc. It greatly reduces the risk of accidental unscrewing of connected elements. Professionals every day are discovering the sealing power of Würth’s thread locker
 

AN ANAEROBIC GLUE WHICH IS USED TO FIX AND SEAL THE BOLTS

 Also known under the name "thread stop" or "screw lock", our thread lock belongs to the family of anaerobic adhesives, which harden in the absence of air, on contact with metal. It can be used on all existing threads (screws, nuts, studs, threaded sockets ...) and works to:

• prevent a threaded system from loosening unintentionally, under the effect of shock or vibration
• seal said threaded system, to protect it from corrosion. 

APPROVED, RESISTANT, ECOLOGICAL AND PRACTICAL THREAD BRAKES
 

Some of our thread lockers are NSF-approved in accordance with the ANSI61 standard. Würth screw adhesives can be used in fields as varied as automobile and naval construction, the manufacture of metals and tools, machines and engine maintenance, electronics and food production areas. Our thread locker products for professionals are proven to:

• resist thermal variations as well as many alkalis, gases, solvents, oils and fuels
• not harm the user and the environment (they contain no silicone, oil or solvent)
• be very easy to use, even with one-handed, thanks to their patented dosing cap. The cap allows you to pour only the quantity of product you need, and leaves no residue in the distribution neck.
  
 

DIFFERENCES BETWEEN NORMAL THREAD STOPPER AND STRONG THREAD STOPPER
 

To obtain a good seal: make sure that the two parts to be assembled do not show any traces of grease or dust, then coat them with the adhesive before proceeding to assembly. Still unsure which thread locker to choose? Take into account the specificities of our two flagship models:

• the strong thread stopper is ideal for parts that are subject to high stresses
• the normal thread stopper allows you to dismantle your threaded system more easily afterwards (while opting for a strong thread lock, you will need to heat the fitting to more than 250°C to take it apart).
