The Stovebolt Site Forums The Shop Area General Truck Talk A new fastener -- what do you think of this?

Need some help. We've been getting some junk mail, but it has a very excellent topic (I guess). Does anyone know about this stuff. Would it make good information in a tech tip?

Info is below.

Thanks,
Peg

Pert ...pending patents on its technology. Said to be the most significant fastener design in 25 years.

TineLok vibration-proof fastening system which incorporates its
proprietary and patented enhanced locking nut and bolt system do not loosen or vibrate.

This design is critical to many military applications. The US Navy has been testing this technology now for over a year.

I went to their website and this is a paper describing their product.

The only downside of their bolts? Normal tools are used to install, special tool to remove. My wife says I have enough tools.

What's old is new again. That nut is similar to the fastening system used on the old electrolock ignition coil caps.

I bet there is another downside: cost! Those things don't look cheap.

that looks to be another of the string of "tamper proof" fasteners that have come and gone over the years that are really aimed at manufacturers [and government contracts ] - haven't found nylocks to have any problems as "vibration resistant fasteners”, even if not properly torqued, and no special tools required

I'd hate to be out in the boonies with my truck and not have the special tool needed to get one of those nuts off.

I guess if I were afraid of someone stealing a particular piece, holding it on with one of these systems would provide a certain measure of security.

I agree with TxLaTx, though. Cost has got to be a down side.

How about Loctight?

Grat, ANOTHER type of fastener that you have to have a special tool to take off!

These would probably find good use in defense equipment and space exploration. Don't look for this kind of technology in your local showroom any time soon.

Y'all have hit the nail on the head. There ain't nuthin' that can be screwed on thight forever. I don't doubt that this fastener is the cat's meow, but from the looks of it and readin' the pictures, the metal material on the nut and the metal material on the bolt do not fuse at the molecular level, and that means weat and separation at the boundary (ah! those darn boundary conditions I studied all those many years ago).

Probably last forever and two lifetimes, but something will shake it loose.

Just my two cents.

Guys
I work in the fastner industry and there is a product out their that will do what they are saying there parts will do. Matter a fact we all have them on our trucks it is a Castle nut~!

But seriously if they (the military) is looking for something better then they might want to look in to the NORD-LOCK Locking washers. Very simple design. This is a two washer system. The washer mate together with cam teeth. The slope of the washers is steeper then the pitch of the fastner. Thus, when the nut tries to rotate to losen the washers actually tighten because of the steeper pitch. Here is their website www.nordlock.com
