It cures on oily surfaces without cleaning, bonds a wide range of metals, and offers a removable yet secure hold ideal for automotive and mechanical applications.

## Description

Loctite 243 Primerless Threadlocker is an oil-tolerant, removable, medium-strength, blue threadlocker designed for the locking and sealing of threaded fasteners between 1/4" and 3/4". It not only works on active metals, but also on passive substrates such as stainless steel and plated surfaces. It tolerates minor surface contaminations from various oils, such as cutting, lubrication, anti-corrosion and protection fluids.

Review: This 243 formula has a better resistance to oil which can be on a lot ... - Can't go wrong with the Loc-tite brand. High quality product that hasn't failed me yet! This 243 formula has a better resistance to oil which can be on a lot of hardware, and oil can cause failure of many threadlocking formulas. This formula is highly recommended where failure rates need to be at a minimum to none. I hope this helps your decision whether to purchase or not, if it did, please vote. Thank you!
Review: 243 Blue Loctite - Nothing much to say about this, it is Loctite, so a brief of what I use it for: I use the 243 blue to secure bolts on my Harley that I may need/want to remove later, and to secure grip nuts on my pistols. These are not things that I plan to remove anytime soon, and want to make sure they stay put until I may need to remove them. I use the Purple 222MS to secure grip screws, sight set screws and those few Harley bolts that I remove often. The purple holds against vibration, but is easy to break loose with a little torque. When I need to make sure something does not move at all, I use Loctite Red 262. This takes a lot of torque and heat to remove. Do NOT use this until you know how strong it is and you know how to remove it. Do NOT use this on any screw you want to remove.
