    Default Torque specs

    I am looking for a chart or list of average torque specs range. I have not been able to find a general guideline. I understand that every manufacturer has their own torque specs. I am looking for a range for action, ring and base screws.

    Huh? Torques are based on bolt size, threads per inch and material involved. Internal engine parts and some aluminum situations get a torque wrench. Everything else gets gut 'n tite.

    The manufacturer of high end rings, bases, Etc. usually give torque specs in the manual. Same with a lot of the higher end rifle action screws.

    The ol' German torque, "Guten Tight" works on many things. I use an inch pound torque wrench on rings and bases based on manufacturer's recommendations. I had an instructor point something out an an AR Armorer's course. Any use of a thread locker will lubricate the threads to the point where it will have an impact on the torque wrench and cause a slightly over torque situation. It makes sense in theory. A quick Google search yielded the following from Artificial Intelligence:

    Yes, thread locker can affect torque, typically by slightly increasing the required torque to tighten a fastener due to the added friction created by the adhesive on the threads, although the primary function of thread locker is to prevent loosening from vibration, not to significantly increase tightening torque; therefore, it's often recommended to slightly reduce the applied torque when using thread locker compared to a dry thread connection

    added friction created by the adhesive on the threads
    ?

    Interesting. I have read the applied, not set up, thread locker fluid acts as a lubricant, causing over-tightening. Then, on the other hand, lubed threads simply allow a deeper bite within the threads, and the applied torque (such as with the FAT wrench) will be true torque.

    An AI explanation:

    When torquing gun fasteners, it is generally recommended to use lubrication on the threads, as this reduces friction and allows for more accurate tightening by requiring less torque compared to a dry fastener; always consult the manufacturer's instructions for the specific lubricant and torque settings to use.
    Key points about lubricating gun fasteners:

    Reduced friction:

    Lubrication significantly decreases friction between the threads, enabling the bolt to reach the desired preload with less applied torque.

    Improved accuracy:

    By minimizing friction variations, lubrication can lead to more consistent tightening and reduced risk of over-tightening.

    Preventing galling:

    In certain metal combinations, lubrication can help prevent galling (metal-to-metal sticking) during tightening.

    Important considerations:

    Correct lubricant:

    Always use a lubricant specifically designed for fasteners, as the wrong type can degrade performance.

    Torque adjustment:

    When using lubrication, you will likely need to adjust the torque setting downward compared to a dry fastener to achieve the same preload.

    Manufacturer's instructions:

    Always refer to the gun manufacturer's guidelines for the proper lubrication method and torque specifications.

    Howz that for adding to the confusion :-( Sorry, was not my intent...

    I understand that torque is relative to the screw size, manufacturer, composition, etc. I’m wondering if there is a list of typical torque ranges for rings, bases and action screws. Thank you for your help.

    Yes. This is what I hoped to find. Thank you!
