The last bottle of locktite you’ll ever need to buy!
Locktite is awesone. This is a huge bottle of locktite and therefore a huge bottle of awesome. If you’re sick of paying $10 for a 6mL bottle of threadlocker and want to take charge of your thread locking future - and possibly do so for future generations - this is the bottle of Locktite 243 (blue) for you!
