The evils of threadlocker

That works. I've done it to remove scope mount screws that had been sealed in. - dan
In the instance of disimmaler metals thread locker serves as a barrier reducing galvanic corrosion and will actually aid in ease of disassembly. ie bare ss bolt in aluminum the alu will corrode and lock the bolt in place often either breaking the fastener stripping the remaining thread completely or require the hole to be redrilled inserted or oversized.
I have used thread locker and similar glues since many decades. Threadlocker is not the problem, using threadlocker wrong and low quality screws is a problem. One has to also understand that long thread lengths for example 3x diameter glued with thread locker will require much more torque to open than say 1x diameter. Most forget that. Biggest problem on screws is galling of for example 304/316 stainless screws on 304/316 parts. Threadlocker will act as a lubricant in and out. Mild steel and steel screws threadlocker reduces the chance of rust in the threads. As well as different materials that have corrosion issues.

ooooh.... I need to get some of that green lock tight
I hate lock tight on scope bases and rings.

What does this mean? Thread pitch is flat?
Rifle ring fasteners are usually #6-48, and #8-40, are they not? Which use a unified thread pitch, both in pitch diameter and thread pitch. The thread angle, is a normal 60° thread. Which is the same as a standard bolt you pick off the shelf. So I am still confused.
A flat thread pitch would refer to a square cut thread?? Which they are not. They are a standard 2a fit,threading into a standard 2b fit, as well I believe. So they would have roughly the same thread engagement and angle as any olf regular UNF fastener you pick up off the shelf, changing slightly depending on diameter of course.

They are not a steeper angle. Thread angle is still 60°.
Unless you are referring to helix angle?? Which of course changes as pitch changes. But that is not thread angle.
What about nothing!!
I started working in a gun shop in 1977
i have built rifles i have done hot costic bluing
i have done all aspects of gun work likely mounted 100,000 scopes
Never once have i used any locking agent
degrease threads male and female and that's all you do
just saying
still mounting scopes
Now all you internet educated gun people tell me how to do it
and go

Same way I mount mine. Although before I had a torque driver, I did use the low strength loctite. I was just guessing on torque, and didn't have the best of luck always just re-checking after firing rounds. I usually forgot. So they where guaranteed either under torqued or over torqued.
More than one way can be correct. I doubt anyone would say your way is wrong and doesn't work. I think everyone should do what they have the best luck with.
And I doubt anyone figures out what the correct torque values are with the amount of loctite they add to the screw. Since on that small of fastener, even a small amount of loctite makes quite a large difference. Torque values are generally dry torque, unless otherwise stated.
Poor terminology on my part. I was talking about thread angle. Any way I didn’t know a standard bolt threat angle is also 60 degrees.
I do know my #6-48 screws dry torqued at 20lbs have not come loose and those guns have seen some serious use in the mountains.
Yeah, basically all common fasteners in North America are some type of unified thread, which are all 60°, regardless of coarse, fine, extra fine, special, etc..
So thread angle is more than likely, on any scope ring around here 60°. So same as any old bolt you would commonly use. Thread helix angle would be what you are meaning to refer to, I am assuming.
Helix angle(lead angle) changes, as threads per inch(thread pitch) changes, relative to the pitch diameter(effective diameter, also the most important measurement of a thread). Think of a ramp, or inclined plane in a helix I guess.
Might as well warm them up a bit with a sharpened piece of tungsten and some amperage. Make sure there are good and solid.Well if you really want your bases solid and no chance of them moving put JB Weld on the screws and between the action and base.
