opinions on posi taps

I'm not an installer and have seen this subject come up a few times now in my time on the boards. I was hoping some of you experienced guys could clear up my confusion as to which connector(s) are the wrong ones to use.

I see both Scotchlok and Positaps mentioned in most of these posts.

Scotchloks:

Positaps:

Now I know that soldering is the best, but which of these are the ones that we should not use at all (or both?)

Is there any connectors that are considered ok to use?

Thanks :)

you shouldnt use either at all. but if you were desperate then i think the positaps would be a better route over scotchlocks.

i find that any form of connector are unrelaible. after soldering nothing can really come close.

I thought Scotchloks and T-taps were the same, and made by 3M? I know Swenco makes the Positaps.

3M doesn't make Posi-taps, Swenco does sneakycyber. Read my other post again...

common sense,

which is better, to attach two pieces of steel together using a screw or weld?

same basic principal for wires

scotch locks are the "lazy mans" fastener

I think they were introduced to the market as a "temporary"  fastener for stationary machines, the original designer probably intended them to be replaced by solder eventually.

Like the illustration!
