Threadlockers

Threadlockers are liquid resins that are applied to threaded fasteners to prevent leakage, loosening and corrosion. They are also known as thread lock adhesives or thread locking fluids.

Threadlockers should not be confused with retaining compounds. Retaining compounds are higher strength and designed specifically for bonding components.

Conro offers a wide choice of threadlockers from major manufacturers.

Conro  is an authorized distributor for Henkel Loctite.

How do threadlockers work?

After application, the resin cures to a solid when exposed to metal ions. This allows the liquid to flow evenly into the threads and gradually harden.

The process happens in the absence of air (anaerobic). Threadlockers cure at room temperature. They work on most metals, including steel, aluminium and brass. Most liquid threadlockers are designed to be applied at the moment of assembly. Some formulas can be applied on parts that are already assembled.

Key advantages of using threadlockers

  • Preventing loosening due to vibration
  • Preventing corrosion between threads
  • Preventing leakage
  • Providing temperature resistance
  • Lowering maintenance and manufacturing costs
  • Lubricity improves torque during assembly
  • Easy to dispense and apply

Types of threadlockers

Threadlockers are available in different strengths and viscosity, to suit specific applications. They are usually colour coded to indicate strength.

  • Low strength: used on small screws that require regular adjustment. The low strength adhesive allows the fasteners to be easily removed.
  • Medium strength: used on medium size fasteners. Allows for disassembly using hand tools.
  • High strength: used in permanent assemblies such as heavy equipment. Provides resistance against strong vibrations. Offers the highest holding ability.

Other varieties are surface insensitive, or highly resistant to heat, chemicals and vibrations.
