I am doing some modifications to my M/H, but am having problems crimping a lug onto 10mm cable. I successfully crimped some 6mm cable, but the crimp on the 10mm cable still feels loose.

Does anyone know what the A/F dimension is for the jaws on a 10mm crimp? I have measured 5.9mm, 5.9mm, 5.6mm (Not a true hex)

The I/D of the crimp is 4.8mm and the O/D is 6.4mm. (The impression is that the wall thickness is thin)

I am not sure if it the crimp or the tool that is at fault.

If you are crimping tube lugs onto the likes of welding cable or any multi high stranded wire it will require much more compression
For 35mm I have to use 25mm dies

I would crimp it with the 10 and follow it with the 6 but not all the way , just enough to secure it

@Techno Thanks for that suggestion...... As a starter, I have re-crimped it with one jaw still set to 10mm, and the other set to 6mm, and it now seems very robust.

I will also try your 10mm then a partial 6mm on the next connection. (I am wiring in a CTEK D250 Dual)

I usually do similar- crimp until firm then down a couple of sizes which locks it tight. If it is somewhere where corrosion may occur after crimping I heat the crimp with a soldering iron and let solder run in the hole just below the bolt hole then put a heat shrink sleeve on it

@Landy lover Thanks, I've just done that too, and am now confident I'm getting good joints.
