I was mounting a scope at the LGS and a gunsmith that helps us on big sales came into the store. He saw me putting blue threadlocker on the scope rings and told me I shouldn't do that. He said over time the threadlocker will break down and turn into lubricant and the screws will work loose. Any truth to this or is he just, "I'm older and know better than you boy"?

Been using Blue Loc Tite for years and my AR gets pretty hot running 3-gun, never had it liquify
|

Non-hightemp threadlocker may melt at higher temps, but I wouldn't call it a lubricant and your stuff may work loose. But will take time and constant heat.
Use red threadlocker for those applications. |
|
..it will be a bitch to get the thread locker off...
for scopes I recommend the weaker version "purple" thread locker... blue is not that bad Red needs heat but purple works.. leave the green alone... and I have never had it "Turn to lubrication" <----- Professional gunsmith not a chemist.. |

FANTASTIC!!!!
Pretty much every rifle, optic, mount and sight in my safe is now SELF-LUBRICATING!!!!!!!!! Off to threadlock the wife.... ETA: If I'm not back in 20 minutes, call a gunsmith. |

I use a lot of blue threadlocker.
I highly doubt it. I've removed things that were loctitied for years and the residue is always dry and crystalline in appearance. |
|
Red doesn't do any better with heat, it's just stronger. Use Rocksett for high-temp applications.
That being said, if your scope rings are getting hot enough to melt loctite,you're doing it wrong. |

Loctited engine header bolts don't end up lubricated. When removing them they end up having a hardened type of material(loctite) on them, so I'd say it is bs.

Why not just ask for scientific proof? Then when he says he can't get it, call BS!!
|
|
I have used it extensively on scope screws with no problems except when WD-40 is used, it will dissolve blue Locktite.
|
|
Total BS! I've been using all different types of Loctite products for years, never happened and never will. Almost all of their thread locking products are anaerobic, they set up in the absence of air. No amount of time will change them into a "lubricant". Hope you never let that guy near your guns.
|
|
Yeah, lubricant.
Which is why it's so fucking easy to turn out the fasteners after they've had loctite on them. Guy's a retard. And I'm an old guy, so I would have had fun telling him that. |
|
I only blue locktite scope base screws that go into a receiver. The rings don't need them and bases that clamp onto a rail don't need them. IMO. I've only had blue locktite seize up on a very, very tiny screw, much smaller than any scope ring screws. Never seen it turn into oil but they say you can dissolve locktite with new locktite. Will have to try that on that struck screw one day.
|

Thread lock will turn to liquid at high enough temps and will loose its'' thread lockiness and let the screws, bolts, nuts, whatever back out. It doesn't turn to a lubricant.

View Quote He's an idiot. the only way that he is even remotely correct is that if you put it on a part that gets hot enough for it to liquify it will lose its holding ability. Scope rings don't get even near that hot. |
|
If you're talking about putting 242 on the rings themselves he may be right,the screws on the other hand are fine.
|
|
Even if true the correct answer is "who gives a shit".
PROPERLY installed screws are lubed when they are installed. They do not come loose. |
|
Sounds like there's a market opportunity for Tactical Loctite in FDE for $50 an ounce.

Loctite is incredibly slippery when exposed to oxygen. However when it is in a thread assembly where no oxygen is present it forms a solid epoxy bond. It is resistant to vibration. Loctite does break down when exposed to direct heat over 150F. You can also break the bond by turning it past it's break tq number.
Red Loctite is not recommended for most fire arms applications. The break number is far too high and the 27x range of loctite is for larger sized bolts where either an impact or heat can be used for removal. For most firearms applications such as scope ring bolts, mount parts, rail parts, etc. Use 222 for coating threads before assembly. or Wicking 220 or 290 for post assembly treatment. |

You lost me at window-licking fucktard....I mean gunsmith.

Leupold recommends lubing screws only. So do a few others.
I used blue locktite only on receiver screws because they tend to be very short therefore you don't get much tensile stretch to hold them tight. The ring screws and cross bolt screws for rail mounts have enough stretch and don't need adhesive. Just lube those screws. Use a torque driver to the specified screw torques and tighten gradually and evenly. |

Good to know. I'm going to start running it on my bolt carrier.

It's a great comment. Now you know you need to look for a better 'gunsmith.'

He was trying to be a know it all. Doesn't liquefy one fucking bit, even under heat.

View Quote None whatsoever. I put threadlocker on screws that hold important components in aircraft engines where it gets significantly hot. The threadlocker is what keeps those screws *IN* the engine, and the important bits attached to it. A C130 engine wiggles and shakes more than your rifle ever will. As much as I'd love to see what might happen if a Torque pickup, tach generator, or oil quantity xmtr came off in flight and bounced around the inside of an engine, I don't want to have to fix the after effects, so use threadlocker. |

Non-hightemp threadlocker may melt at higher temps, but I wouldn't call it a lubricant and your stuff may work loose. But will take time and constant heat. Use red threadlocker for those applications. View Quote Red is for when you absolutely, positively, never want that part coming off again ever. For extreme high temp applications where you might want it to come off again, use yellow. It's what the Air Force gives us. |

That makes perfect sense. Loc-Tite has made a crap load of money selling a product that actually causes fasteners to come apart faster. In fact, next time you have a seized up fastener, don't spray it with PB Blaster/Kroil etc., hose it down in thread locker.
|

What should have been a red warning flag flying in your face was you were in the Local Gun Shop. The guy telling you this BS was probably a jerky selling SEAL.

I'm gonna go out on a limb and say that Loctite like most other solutions, separates a little when sitting in the bottle for an extremely long time. I have noticed after a long time that I need to shake it up a little to get it back to normal consistency. I'm sure this chemical genius of a gunsmith observed this and drew his own conclusion that it somehow turns to another product completely. Even when it's a little thin it still dries and works as advertised, just runs a little. Maybe ole Heisenberg the gunsmith can make us some gold from chicken shit.

Did you know that loctite taste delicious, you can use it as a sugar substitute if you need to
