Just to clarify, the nylock nuts are for 12V batteries in my boats to replace the wingnuts. That is the only ones I found but now I starting to look around
thanks you made my day _________________ Brent Barrett |

RE:changing nuts on battery to nyloks.
Check out the Tugnuts Albums ---"Starry Night" --modifications. It contains a picture of an overheated nylock that was used on a battery terminal.
Sorry, I can't hot link it or copy the picture.

Here we go / Let's make it easy:
Melted nut on left and new nut on right.
Lose connector on our stern thruster battery lead to the melted nylock nut you see on the left.

The key point is a loose connection.
Right?
A wing nut can melt, too
Whichever fastener you use, it needs a lock washer, dielectric grease and tighten with a wrench or socket |

From the picture, I don't think the metal part melted, just the insert. I don't believe it would get hot enough to melt metal... sure got dark though!
Ever dropped a wrench across a 12v battery? Boy does it get hot in a hurry...

yes I have
on a side note or tangent
Battery technology keeps improving and the increased capacity along with a smaller footprint.
I can no longer charge my two 9.6v battery packs for a DeWalt cordless drill after years of use. It was the best money I spent after the first Makita cordless drill bought n 90s |

Yes, and it really pays to buy QUALITY cordless appliances. BIG difference!
Too bad the replacement battery packs are $75-$90, but by the time you reach that point, the newer tools have better performance, and usually are powered by a newer generation of battery technology.

I bought 2 from batterydepot.com for $54 shipped.
The drill is still useful and a workhorse plus I have 2 flashlights that uses the same packs. |

The above link also has good videos and a discussion about the two-nut system and other fasteners and fastening systems.
I thought about the two-nut system for the battery terminals, but didn't want to stir the pot too much and turn this thread into another single vs. twins epic discussion.
After seeing the videos and graphs, I think I'll settle for two nuts tightened against each other, fastened further with Blue Locktite, and drilled and wired down aircraft motor style. (Old School again!)
Gimmie that nut-busting Junker Machine, and let's run some tests!

Another nay for nyloks, they must also be replaced after each use, otherwise they quickly lose whatever holding advantage they might have. Also products like corrosion-x and ACF-50 are great on electrical connections to prevent corrosion. _________________ Lenny |

Is there a tutorial on using wire? |

thanks very interesting to watch
I wonder what the process used at NASA. I doubt they are using nylocks. |

O.K., here's what I do with battery terminals:
First, make sure the batteries are firmly secured, and the terminals and lugs are clean.
Second, stack the lugs onto the terminals in such a manner that, when tightened, there will be no gaps.
Third, tighten with nylok nuts to about 10 ft-lbs of torque. I've never had or heard of such an application coming loose, but I suppose it has, somewhere. I don't worry about heat generated at the terminal because the nylok has to come loose first, or there has to be substantial corrosion on one or more of the lugs or the battery terminal itself. I have control over those conditions by routine inspections. I don't use split ring lock washers because if you use a flat washer, lock washer and standard nut, you have the functional equivalent of a nut with an oversized, smooth bottom. The lock washer doesn't do anything, other than supply a very limited force along the axis of the terminal post. But, if you want to use split rings, fine and dandy.
Fourth: apply multiple coats of West Marine Electrical Connection Sealant (costs about $8 per can) to the entire connection (terminal, lugs, nuts, etc.) until you can't see any metal showing through. This way, you don't have exposed connections, which is a big no-no, and the whole mess is so locked in place that it's not going anywhere.
If anyone knows of this setup failing on a C-Dory class boat, let me know. |
