Do I need threadlocker?
Threadlocking compound is a commonly used product in many applications where screws are used that need to stay in place. Since firearms generate a good amount of vibration and shock when fired, it only makes sense to use such a compound on mounting screws to make sure they stay tight and do not loosen or back out, or does it?
We recommend all bases being mounted to a firearms receiver use a non-permanent threadlocker, which is typically a blue or purple color. A firearm barreled action is under immense stress when it is fired. This creates shock and vibration which can loosen the small screws that are commonly used to mount bases to the receiver. A small application of threadlocker, and the proper torque of no more than 25 in/lb (steel receivers only) will ensure that the base screws stay tight, even on the harshest recoiling rifles.
Warne does not recommend the use of threadlocker on our rings. When a threadlocking compound is applied to screw threads, it can act as a lubricant. When you torque lubricated threads vs. torquing dry threads, when using the same amount of torque, more pressure will be put on the scope tube due to the lubricated screw being easier to tighten. We recommend 25 in/lb of torque for all Warne rings, and that torque spec is intended for dry threads. If threadlocker was applied to the threads, and the ring was torqued to 25 in/lb, there is potential for scope tube damage. An easy way to make sure you are tightening mounts to the proper torque is to use the Warne TW1 torque wrench. It is preset at 25 in/lb with a T-15 Torx bit for easy installation.
Since the force and vibration are in a different orientation for the rings, they do not vibrate loose like base screws can. So remember, non permanent blue or purple threadlocking compound on base screws only torqued to 25 in/lb (steel receiver guns), and rings dry threads torqued to 25 in/lb will give you a mounting system that is solid as a rock.
