Loctite 262 Acrylic Anaerobic Threadlocker Red 50ml

Loctite 262 is a one-component, red, medium to high strength anaerobic threadlocker (dimethacrylate ester). It is designed for the permanent locking and sealing of threaded fasteners.

Typical use: large bolts and studs up to M25. It is a thixotropic liquid that cures without air between close-fitting metal surfaces, and it fluoresces under UV light so the applied product can be inspected.

Where this product is used

• Permanent locking and sealing of large bolts and studs up to M25
• Threaded fasteners that are not meant for routine removal
• Threads that must be sealed against leakage as well as locked
• Fasteners in contact with motor oil or 50/50 water/glycol
• Assemblies where the applied product is checked under UV light

Features

• Medium to high strength, for permanent locking and sealing of threaded fasteners
• One component, no mixing
• Red liquid with positive fluorescence under UV light
• Medium viscosity, thixotropic, so it stays where it is applied
• Anaerobic cure, with an activator available as a secondary cure
• 22 N·m breakaway torque on M10 steel nuts and bolts (24 h at 22 °C)
• Removable with localised heat to about 250 °C

Key specifications

Choosing the right option

For a medium strength grade see Loctite 243 Medium Strength Threadlocker. For a high strength grade see Loctite 263 High Strength Threadlocker or Loctite 271 High Strength Threadlocker 50ml.

For bolts and studs M25 and larger, see Loctite 277 High Strength Threadlocker 50ml and Loctite 272 High Strength - High Temperature Threadlocker 50ml.

Using it

If the material is an inactive metal, or the cure is too slow, spray the threads with Loctite Activator SF 7471. SF 7649 is also an activator.

To disassemble, apply localised heat to the nut or bolt to approximately 250 °C and remove while hot. This is a removal temperature, not an operating limit.

Cure speed depends on the materials, the gap and the temperature.

Storage and handling

Store unopened in a dry location. Temperature range 8 °C to 21 °C as the optimal range. Storage below 8 °C or above 28 °C can adversely affect the properties of the product. Do not return used product to the container.

Limits and safety

Not recommended for pure oxygen or oxygen-rich systems, or as a sealant for chlorine or other strong oxidisers. Not normally recommended for plastics, as thermoplastics can stress-crack. Check compatibility with aqueous washing systems. Read the safety data sheet before use.

Check the graph against your service temperature.
