Need Some Help "Unsticking" Loctite

Disclaimer: Despite my current frustration, Daniel Defense is a great company with great customer service and products. Love them.

The problem: Got a new DDM4. To make it CA “compliant” a “bullet button” must be “installed” for legal shipment onto CA. Well the compliance dept. over at DD has apparently decided that “installed” means to Loctite the holy crap out of it. I prefer to use the Raddlock type of bb, and I frequently travel out of state with my guns, where I switch to a standard mag release whenever it is lawful to do so. I have made two calls and an email to confirm that blue Loctite is exactly what was used.

So far, I have been unable to break the little threaded collar inside the bulletin button loose. I have tried a mini torch to burn off and or warm up the Loctite. When several attempts at that failed, I tried soaking the area with MEK for an hour or so. Kept it wet by applying it with a Q-tip and rewetting it every few minutes. It still wouldn’t budge.

Any ideas from the huge pool of knowledge and experience here?

Try applying some heat with a heat gun.

Like SW said… You should see a little puff of smoke when the Locktite gives up. GH

To release blue Loctite (242) it has to be heated to at least 400*F. It is best to do it with a heat gun while applying torque to the fastener.

Even though the Loctite will break down when it gets hot enough the powdery residue can still interfere with releasing the threads unless it is kept hot for the first few turns.

Yep 1 to 1.5 min on high setting with a heat gun will usually break down any Loctite. On gas blocks where they’ve been bedded with green or red Loctite I use a MAP gas torch for 15-20 seconds. If 15-20 still doesn’t work try 10-15 sec more and try again.

This and Rob’s Suggestions are what worked for me in the past. The MAP torch will work quickly. Just be careful.

Blue does not need to be heated up to release, that’s the whole point of it. I use it on several of my guns and have never needed to heat it to release.

“Fill spaces between threads to produce a secure one-piece assembly that will not loosen under stress, but can be removed with hand tools”

as opposed to the red which reads

“■Disassembling requires localized heat (>550°F/260°C), hand tools, and disassembly while hot”

If it’s 242 It’s operating temp. range is -65f/300f

To break the bond you only need to provide 110 in/lbs at room temperature.

There is a high temp medium strength blue that requires 170 in/lbs…

There’s also a blue that requires 230 in/lbs…

I won’t argue that blue doesn’t need heat to release under normal circumstances but heat will make it easier to remove fasteners bedded with it. Especially if the blue is on the shoulder of a fastener with a small socket head compared to the thread diameter. GH

On small parts I apply heat with the tip of a soldering iron.

Always nice to see companies go above and beyond the norm in today’s culture. I’ve had great experiences with DD, B5, and BCM to date and will continue to support them because of it… Although it might be time for me to give Noveske and KAC a chance :smiley:

can’t open link. Is it restricted or bad link?

Because he posted it in the feedback area and that is not what the feedback area is for.

Sorry. Please forgive my ignorance. Where should it have gone, and is it deleted or moved?

If you found a solution to the issue you originally posted about, post it here.

I ran into this same issue with rail sections on my VTAC Alpha. Little buggers are on there good.

Someone I know likes to talk. :smiley:

Thank you for posting my other thread here for me. I though it was lost. Much appreciated.
