Plenty spendy for what you get. Use sparingly.

And use only the blue or green. Red can make it really tough to remove.

If you go to Midwayusa.com there is a video that shows you how to install a scope. The guy uses purple loctite. [:D]


If you are unsure which type threadlocker you need, visit Loctite.com and type the number in the description into the search engine to view specific information from Loctiter

Don't EVER use red Loctite on a gun or anything else that you might want to take apart. On scope mounts and rings only use blue or purple Loctite. If you do use red you won't be able to take it apart after it sets. Any chain hardware store, most auto parts stores and even Wal Mart have Loctite. If all those fail you then try an industrial supply house that sells bearings and seals.

JustC

just degrease and de-oil the screws and threads and there is no reason for loctite. They loosen up because of oil/grease on the threads.

Mobuck

If you don't degrease the screws AND the holes, the loctite won't work well anyway.

mrbruce

If the screws are cleaned to the bone along with the holes, the screws will loosen eventually
from the vibrations if they are not Loctited in tight.

wcoxy2003,

Locktite has a number of products out that do what they originally had one product to do. Blue is soft but won't let your screws spin. Red is hard and won't let your screws spin but doesn't take well to screws coming out without possible damage to the screws. Locktite 406 is essentially aviation grade super glue. NEVER use anything resembling super glue. Unless you have a solvent to take it down with. Solvents like that usually cause cancer and are not necessary.

JustC noted you can get the necessary torque without going to Locktite type products. One of the reasons I advocate using the soft locktite is so that when you put the screws in and torque them down you get less damage to the threads using wet-torque(using locktite or thread lubrication) instead of dry-torque. Dry torque as JustC noted will leave a lot less problems in the future to fix and holds just fine, if you don't take the scope off the rifle numerous times.

Fasteners loose for many reasons;
1. Under torqued for the application reducing holding power.
2. Over torqued causing thread over elasticity losing holding power.
3. Dissimilar materials that corrode reducing thread strength.
4. Undersize, underrated fasteners. Fastner strength isn't in it's
length, but it's cross sectional and material.
5. Foreign matter in the threads. Dirt, oil, etc.
6. Wrong thread pitch.
7. Cure time too short.

Loc Tite is a superior fastening agent over bare metals in many of the above. Especially in reducing-eliminating rust (oxidation).

Think of it application range by caliber & color.
222 Purple fasteners up to 1/4". Easily removed by small hand tools
242/243 Blue for fasteners 1/4"-1/2"-1". Moderate removable force
272 Red for high impact, high stress. Hard to remove. Heat needed

The stronger the Loc Tite the better quality, better fitting a tool must be. Often when removing red, I use a heat gun, soldering iron on the fastener head to prevent damage.

Any hardware store should have blue locktite. Home Depot and OSH have it. I have heard for gun applications that green is better than blue.
