Does anyone know a good make? I bought some generic Chinese things the other day and they are poop. They cheap, thin, bendy rubbish. They barely grip the wire. Not being experienced with these things, can someone recommend a decent make?

I've just bought some Draper ones for about £20. They seem to do the job.

Same here, there's a Draper Expert set of crumpets for about £17 which I've been using for the past few years and it's pretty decent.

Draper Expert tools tend to be quite decent in stark contrast with the cheap 'regular Draper' stuff.
 
Usually use cpc farnell for such purchases or RS, both sell good quality stuff and would refund if you have issues;
I have mostly used chocolate blocks/solder/shrink-wrap for car electrics

I assume you’re looking at relatively standard butt connectors and similar?

I’d be looking at 3M, TE Connectivity and Molex

Yes, thanks. What I need are all standard thimgs. but the makes on Amazon are disappointing. I am using mains not 12V and although the ones I bought were rated at 240V, I simply did not trust them at all. The crimp tool itself was reasonable, but the terminals were horrific. As I said before, they were thin, bendy, and didn't grip the wire very well. I had thought of crimping ferrules on them first but then decided to see if I could find some decent ones.

ANother thing to be aware of, when you get decent lugs, is make sure you are using the crimper the right way around, normally the coloured dot is the side the wire enters fromn (But inspect the dies on your own crimper to confirm). The proper name for the insualted crimps is PIDG (Pre-insulated Diamond Grip). One side crimps the end clost to the terminal in an even rounded way to crimp down on the conductor, and the end where the cable enters goes into a diamon shape to grip the insulation

Rather solder tbh unless you really need to crimp like on an O2 sensor etc.

Soldering is not considered safe with high current sources. This is because a short can heat the solder enough to make it weak and the joint fail. It doesn't matter if it's 12V but it can kill someone if it's a few hundred volts.

Cembre, Hellermann Tyton, Draper, all decent.
Just avoid no name Chinese stuff and you should be ok.

OK.
I have looked around and noticed that most "decent" makes are significantly more expensive and that probably accounts for the difference.
 
Bought a few different sets from amazon and Ebay. All a waste of time. Never a solid crimp. Went to my local motor factors a bought some there
Soo much better solid crimps that worked everytime.
I guess you definitely get what you pay for in this case

What are you crimping then? I initially thought you was talking about small things.

When I did my battery relocation I bought a proper hydraulic crimper and got all my bits for different guage wire from RS components. I fused with those cube fuses. Works really well.

RS components are my go to most of the time for anything of that nature really.

Yes, I posted in Motors because I thought people would know which brands to get, but I am actually using them with mains.
