Preload is the key to a successful joint. Lockwire (like a castellated nut) is really only intended for dynamic joints. In the case of a structural joint that is for whatever reason is overloaded, lockwire does not prevent failure…… it simply becomes a lanyard to retain the bolt head that pops off.

Thanks for this interesting test video! I have found that Nylock and Metalock (like your Top Lock) are almost 100% effective because no matter how much the bolt loosens they will not freely spin off the fastener. Cotter pins are almost as good, however they can shear off, allowing the nut to freely unscrew with no warning. When the Nylock or Metalock are loosening by accident, they do so gradually so that the parts become gradually looser, allowing noise and vibration to build with time; thereby giving the operator time to stop the machine before it becomes catastrophic.

That's very interesting, the test is BRUTAL, like, not just vibration, but downright impact loads on the system, but it does indeed make a lot of sense when you're just trying to losen up the system as fast as possible. Kinda surprised about some of the bad results tho, this begs the question of whether they have different applications that would benefit more on their construction, like the ones that bite into the metal being more suited to softer materials or such. One that would have been very interesting to compare is a normal nut, with red thread-lock added.

I will suggest that jam nuts need to be closer to yield in order to stay jammed. Further suggest using a different method for the jam nuts: 1) Apply the required torque with the first nut. First nut should be the full nut. My sources disagree with your sources (name yours and I'll name mine:) ) 2) Jam the second nut at max torque allowed for the bolt, rod, stud, or shaft (while not allowing the first nut to turn and this may be much higher torque than allowed for the first nut). The jam nut does not need to be a low profile nut: it can be full. 3) I am not suggesting that clamping force will be unaffected by the second nut.

I think you will find, as the tightening torque increases, the game changes. Higher tensile fasteners and higher tightening torques change the game in several ways. Toothed fasteners and spring washers fail earlier as both the hardness of the metal and the tightening torque increses. Plain fasteners hold better as the tightening torque increases. Finer thread pitches increase available fastener tension and friction. one of my favorite combinations is a high tensile bolt , nut and washers backed up by a nyloc nut as a lock nut.

Also, an aside ... was cropduster in Bull Stearmans for 10 years ... ALL critical nut/bolt connections were secured by 'safety wire' (locking wire) and castlenuts. Don't recall a single failure!!!

Because it's much more preferable for the nut to open more than to ever tighten (think about shaking it and making it tighter... never gonna happen, right?), it's quickly accelerating thing that nuts always loosen eventually. Nordlocks try to make it so that more the nut tries to loosen, tighter it gets because the wedges are at higher angle than the fasteners pitch... obviously they'll also fail eventually, but they've been very very robust when CORRECTLY INSTALLED. Try them as well? :)

Couple things. The internal toothe washer and keep lock nut designs are not to keep a bolt from loosening but are meant to ground electrical connections. The teeth are meant to cut throught paint or other surface finishes, equaly true for the external tooth washers. Torque means nothing if you're not lubricating the threads. F (friction) factors vary greatly from the screw to screw even from the same batch. You can apply X torque to 3 of the exact same hardware and not obtain the same clamping force because F vary on each. Direct from the head engineer at Fastenal US, split washers are worthless. Told our engineer dep, they only still sell them because people just refuse to learn. Bellville washers (to keep tension on the bolt assembly during thermal expansion) and Nyloc nuts are the way to go with common assembly applications. For anything with vibration, Loctite, Nord lock washers and Nyloc nuts.

Interesting test. However, not sure there are many applications in the real world, nor is there a nationally recognized standard that says to tests fasteners using this method. Fasteners are typically designed to bolt stuff together, not vibrate like what is shown in this test. IMHO, a Junkers Test (Ref: Junker, G (1969). "New Criteria for Self-Loosening of Fasteners Under Vibration". SAE Transactions. 78: 314-335), which is a mechanical test to determine the point at which a bolted joint loses its preload when subjected to shear loading caused by transverse vibration. There are YT videos that show most methods of fastening devices will fail the Junkers Test unless special washers are used (e.g., Nord Lock Washers), safety wire, loctite, or similar is used.
