Thread lock types

Well let's clear this up really quickly for you: Blue loctite threadlocker is for using on fasteners that you want to unscrew easily. Red loctite is for a more permanent fix, on parts that you won't be loosening for years to come.

What do the different Loctite colors mean?

Loctite threadlockers are primarily designed to prevent fasteners from leaking or loosening from vibration. The difference between red and blue threadlocker is a matter of strength and removability. Loctite threadlocker blue is designed to easily be replaceable with common tools, whereas red is a more permanent fix.

Which thread lock is strongest?

LOCTITE® red threadlocker is the highest strength of threadlocker adhesive. This product cures fully in 24 hours and is available in both a liquid and as a semisolid anaerobic. The red high strength threadlocker products are so powerful they may require heat to be disassembled.

Which Loctite is permanent?

Loctite Threadlocker Red 271 is a permanent solution for locking and sealing threaded fasteners and is only removable once cured by heating up parts to 500°F (260°C).

When should you not use Loctite?

Loctite can't fix a worn-out bolt. You should replace all bolts and nuts that have sloppy threads. For a proper hold, a bolt needs three complete revolutions of threads to be filled with the fluid. Two drops of threadlock is usually enough on 6mm and 8mm threads.

Which is stronger green or red Loctite?

Green is stronger; red might give way in a high stress area. They are quite different products with different purposes.

What is purple Loctite used for?

Loctite Purple (222): Low Strength Threadlockers It's suitable for all metal threading and is great for low strength metals that are prone to fracture like aluminum. This grade will allow for disassembly by hand tools, and the adjustment of screws including set screws.

What is Blue Loctite used for?

Loctite Threadlocker Blue 242 is designed to lock and seal threaded fasteners and prevent loosening from vibration. Ideal for 6-19mm fasteners, this unique formula is great for small motors, mowers, and power equipment.

Is green or Blue Loctite stronger?

Permabond Green Threadlocker HL126 is a High strength Low viscosity threadlocker. Permabond Blue Threadlocker MM115 is a Medium strength Medium viscosity threadlocker. Blue threadlockers are often called removable threadlockers as they can be disassembled with hand tools.

Can red Loctite be removed?

The cured red LOCTITE® product can be removed with a combination of soaking in a solvent and mechanical abrasion such as a wire brush. For female threads, a tap can be used to clear the threads instead of a wire brush.

What is yellow Loctite used for?

Henkel Loctite 577 Medium Strength Threadlocker Yellow is a one component, acrylic, anaerobic threadlocker designed for locking and sealing metal threaded pipes and fittings. The product cures when confined in the absence of air between close-fitting active and passive metal surfaces.

Can I use threadlocker as glue?

Is threadlocker glue? The threadlocker can be used as a glue. However, the adhesive bond may differ for different types of threadlockers. Blue, green, red, purple, yellow color-coded threadlockers are available, with each having different adhesive strength.

Is Blue Loctite strong enough?

Blue Loctite threadlocker is considered to have medium adhesion strength. It can be disassembled with high torque, but it is easier to disassemble with special chemicals and/or heat. It is available as a tape, semisolid, or liquid form, and once applied to the threads it will cure in 24 hours.

How do you remove blue Loctite?

To loosen a Loctite bolt, spray a solvent-like brake cleaner directly on the bolt. Place a wrench on the bolt and tighten it slightly. The solvent will loosen the compound, and you will be able to remove the bolt after several minutes. Gloves should always be worn when working with chemicals.

Is threadlocker waterproof?

Active member. To the best of my knowledge none of the common Loctite thread lock products are water soluble. Indeed, some are resistant to many solvents far more aggressive than water.

What happens if you use too much Loctite?

Threadlockers are designed to fill small gaps in threads, so a little adhesive actually goes a very long way. Overuse may cause the adhesive to spread beyond the required surfaces. Any threadlocker outside of the curing area, where air is still present, will remain liquid and not cure.

How do you remove Loctite from threads?

Do you let threadlocker dry?

Most Loctite threadlockers and retaining compounds will set in 10-20 minutes. It will take them 24 hours to dry into a hardened plastic. This process is called curing.

How strong is orange Loctite?

Loctite 266 orange threadlocker is compatible with metal materials with a 24 hr cure time. Delivers great performance with tensile strength of 270 psi.

What is Loctite red used for?
