    This is undoubtly my favorite youtube channel.
    It's worth mentioning two things. First, your aim in tightening fasteners is clamp load. Clamp load is related to torque but a variety of factors come into play as to what clamp load is generated by a given amount of torque (which is why the torque tables have different values depending on fastener finsh, etc.). Second, when designing a bolted joint, you must consider the material being held together by the bolt. Lots to this as well.

    Nice video, I appreciate the detail, maybe a short overview would be helpful in the beginning. I highly encourage using metric bolts and fittings whenever possible, as the standard has been largely adopted world-wide the exception being home-depot.

    Yet another excellent video from NYCCNC! Keep up the great work!
    I think you may have misspoke, The "N" in NF and NC stands for National, not Normal.
    Now stop reading my post and get to work on part two already! lol

    @saunixcomp Another good practice is before use, set your torque wrench to the max setting and break the torque 6-10 times. It lubricates the internal components of the wrench and helps prolong the life of your wrench.

    Thanks for the video. Just a small issue, the castle/castellated nut is actually a slotted nut.

    In the jam nut method you have to use smaller nut on the bottom, then the bigger one.

    Nice video! Just a few corrections: while the units for torque and energy are the same, it is not correct to say "foot-pounds of energy" in regard to the torque of a bolt. Also, NC and NF stand for National Coarse and National Fine, not Normally Coarse, etc.

    You forgot star washers, I like castle nuts and either cotter pins and/or lockwire. There are also bolts and screws with holes drilled in either the head or also the threaded portion. Aircraft have special fasteners and I belive there are some marine fasteners.

  • @lazystart

    @saunixcomp It would, but by setting it to the highest setting you ensure all of the components of the wrench are taken care of. The components at or below your usual torque setting get used and lubricated much more often than the settings higher than your usual setting.

    Sounds like a silly question but how would one tell when its appropriate to use a washer on the head side of the bolt vs the nut side?

  • @Mavermick1
    @Mavermick1 14 лет назад

    @saunixcomp - Hi. To look at a slotted nut it just a normal hex nut with slots........whereas on a castellated nut, the slotted section is circular. I think the terms are often intentionally combined now, but that is the original definition given to me.

    This is great! I'm trying to teach myself engineering because I make art installations that require quite a bit of engineering (Breathing Room - quick iphone movie), and this kind of systematic explanation is *so* helpful. I am using screws/bolts to make moving pivot points between two pieces of wood - but inevitably the nuts I'm using work loose - which of these solutions wd you recommend? ty!!!

    What to do With Left hand thread Fasteners? I can't find any locknut to use- Especially the (reversed threaded) 5/8-18 UNF fasteners. I love to use the Nord-Lock washers, but I don't think the directional teeth will help on the reversed Threads.

  • @cIappo896
    @cIappo896 8 лет назад +1

    What if the part still needs to be able to move?
    The screw is holding a joint, and that joint moves a lot.
    It's a tiny screw so most stuff would impede its movement.

    Grade 12.9 bolts (metric) are stronger than grade 8 bolts, all else being equal
    ARP bolts are SAE and are stronger than grade 8 bolts as well.

  • @larrylacostjr.2075

    Use super glue and baking soda on the threads adjacent to the nut (where you want it to stop). The nut will never move past the treated thread. Pure and simple. No torque needed.

    @happymark1805 14 лет назад

    distorded thread hex nut lock has one big problem, if You use a torque wrench the torque is not correct because the nut also creates a drag.
    There are also products like loctite and a nut that has two slits in it(don't know what that is called) .

  • @lazystart
    @lazystart 14 лет назад

    @saunixcomp It would, but only the parts of the wrench up to your setting. Going the full range ensures all of the working components of the wrench are exercised and lubed. This is for break-away or "click' style wrenches, many of which on the market today are self-lubricating. However, it only really self-lubricates the parts that it has been set to. This is a practice we have in the Air Force since our torque applications are critical in structural and mechanical components.
