TL42 Glue | McMaster-Carr

The most commonly used threadlockers, these liquids prevent loosening due to vibration, bending, or improper torque. You only need a few drops to evenly coat threads. As you twist parts together, exposure to air is blocked and the threadlocker begins to harden.

Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes; and cadmium and zinc coatings.

Medium Locking Strength—Strong enough for most applications, these threadlockers hold firmly until you break their bond with a combination or ratchet wrench.

Thin Liquid—Seep into tight spaces better than thick liquids, so they're best for fine threads.
