Have you ever questioned which LOCTITE® Medium Strength Blue Threadlocker to use? Did you even know there are multiple kinds?
Of all our thread treatment applications, the Medium Strength Blue Threadlockers are the most commonly used. They are removable with standard hand tools on ¼ ” to ¾ ” fasteners, have fast fixture times, and are available in liquid, stick, paste, gel and tape form. The only question is, which blue threadlocker is right for your particular use?
The four types are:
- LOCTITE® Threadlocker 242®
- LOCTITE® Threadlocker 243™
- LOCTITE® QuickTape® 249™ Blue Threadlocker Tape
- LOCTITE® Blue Stick Threadlocker
Note: Although all LOCTITE® threadlocker bottles are red, the liquid in all four of the products below is blue. The red bottle is what distinguishes LOCTITE® threadlockers from other brands. Learn about the difference between Red, Blue, Green and Purple Threadlockers

The typical repairs that utilize this type of medium strength threadlocker range from valve cover bolts to carburetor studs. This is known as our all-purpose threadlocker, and is also known as the “original threadlocker.” It eliminates the need for expensive lock nuts and lock washers, seals even when it vibrates, and protects threads from corrosion.
