$14.92 $22.95 In stock

Loctite® 222™ Low Strength Purple Threadlocker is ideal for fastener diameters of 1/4" (6mm) and smaller. Its controlled lubricity allows for accurate clamp loads. Parts can be separated using hand tools.
LOCTITE® 222 is designed for the locking and sealing of threaded fasteners which require easy disassembly with standard hand tools. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Low strength Loctite is particularly suitable for applications such as adjustment of set screws, small diameter or long engagement length fasteners, where easy disassembly is required without shearing the screw. The thixotropic nature of LOCTITE® 222 purple threadlocker reduces the migration of liquid product after application to the substrate.

Emily I. ★★★★★

I was a little skeptical about purple vs blue, but this low-strength formula really does make small fasteners easy to remove by hand later. The controlled lubricity also made torque settings more consistent during assembly.

Amelia J. ★★★★★

Finally, a threadlocker that doesn't require a breaker bar for tiny screws—the controlled lubricity makes setting clamp loads predictable. Purple just works perfectly on my computer's 6mm fan mounts, and hand tools break them loose without drama.

Penelope R. ★★★★★

I've been using this on small screws and it’s great — the controlled lubricity makes torquing much more predictable, and hand tools are plenty to break the bond when needed.
