Sta Lok or (Stalok) terminals how far should they screw in

[savageseadog]

At last no political rant or bad taste jokes, a boating question. Have recently made up some 5,6,7 mm Staloks some of them only screwed on about 5 turns leaving about 4 turns exposed. Doeas that seem normal ? The wire was a Compak or Dyform type. Thanks in advance.

Did you use the special Dyform wedges? If so, should be OK.

Ask Stalok. They emailed me some helpful diagrams.

I think it's OK to undo them again to confirm the wire ends have turned over
and you can measure the depth of penetration. They don't need to be overtightened
and some sealant is good, but not cheap smelly silicone.

I was told that there should be between one and two threads showing when it's fully tightened. You can certainly open the made joint to check.

As others have said, both Norseman and Stalok have small pamphlets that show the method of forming the joint in diagrammatic form, so very easy to follow.

Open up one of the worrysome items and see if the wire has formed under the torpedo such that the ends all come together. If they have you had it tight enough.

Problem is you will have threadlock on the threads so undoing will not be easy. The other worry is that the threads have galled and so seized. Thats worth checking for as well.

Thanks for the replies so far. Yes I did use dyform wedges and yes I unscrewed the assembly and checked everything was in place before loctite and sikkaflex. There wasn't a problem with threads stripping.
I did notice that an fitting made a few years ago with Dyform on 7mm showed about two turns of thread. The wire was from Stalok as well, so a mystery for now.

As a point of interest the Dyform cones were an absolute swine to push onto the core of the wire. We had to resort to using grips, hammering and twisting plus bevelling off the wire ends with a grinder plus holding strands in place to get them on. We spoke to Stalok about it and their reply was that there are variations in wire sizes. I can tell you the cones were definitely dyform and the normal 1 x 19 cones didn't fit at all.
So any ideas ?

I wouldnt see that there was any problem. If the ends have formed correctly, there's no obstruction, and you have screwed the fittings up tight, then thats as far as they are designed to go. I would be far more worried if they screwed up the whole way.

Got to remember these things are made in the UK so you cant epect Jap levels of precision and consistency.

Seriously, only Stalok can give you a definitive answer.

 

[savageseadog]

I will have a word with Stalok as there isn't a definitive answer. Will let you know what the answer is.
