My question is ...
1.5mm= m?
2.0mm= m?
2.5mm= m?
3.0mm= m?
5.0mm= m?

1.5, 2.0, & 2.5 is all you really need for the Kraton 6s. I also have a 3mm as I replaced the motor slide screws with a beefy 3mm caphead. Get a quality set of drivers like MIP or ProTek.

m=screw thread size. The mm is what driver you need to use with the screw

1.5, 2.0, & 2.5 is all you really need for the Kraton 6s. I also have a 3mm as I replaced the motor slide screws with a beefy 3mm caphead. Get a quality set of drivers like MIP or ProTek.

The 5mm is for the pillow ball caps.

M is the thread size. For example, a M4 fastener has a 4mm diameter on the threaded area, M2 has a 2mm diameter threaded area, and so on. There isn't always a correlation between M thread size and mm head size: I've seen two different M3 fasteners where one had a 2.5mm head, and the other had a 2mm head.

5mm Allen key is supplied with the Kraton. Like said above just the pillow balls use the 5mm.

first off, thank you for all your answers so far.

well thats confusing lol

so im ordering the MIP 1.5 2, 2.5.

so i get any more hex drivers like the 3.00 from MIP? Since the 5.0 are just for the pillow balls, i will used the supplied tool for that.

I know the MIPS are the goto for the smaller hexs, but should I get 3.0 MIP or will I be ok with another brand?
What about the nut drivers and turnbuckle wrench?

 

[morrjr71]

A 7.0mm nut driver is handy for wheel nuts. The 5.5mm nut driver isn't all that good: it's too long to get to most of the nuts that use them. For the 5.5mm nuts, your best bet is one of these:

Similar wrenches come standard with many RC vehicles. For the turnbuckle wrench, and 5mm/6mm open end wrench will do.

 

[edh]

the kraton exb comes with this

again, do you think I should buy a seperate 5.5mm and 7mm? or just a 7mm and use the shorter 5.5mm?

 

[GraniteFox]

My opinion. Pick up the 3mm as well. For the larger ones I just use a metric Allen set from the hardware store. They are not used much and the larger hex don’t really strip out.

 

[AIan]

I only spent the money on mip’s for my 1.5, 2.0, & 2.5mm hex Wrenches and drill driver bits.

 

[Jerry-rigged]

I can't remember anywhere on my Arrma 6s trucks that uses a 3.0mm hex.

wheel nuts are 17mm, not 7mm.

and 2x, yes, I use the cheap little cross wrench for most 5.5mm screws, and the big cross wrench for the tires. Sometimes I will put a 17mm socket on my electric impact, but that is overkill, (except for the left rear wheel.)

 

[AIan]

I bo a two pack by mistake of these, I never need more than one

I thought it was in 2 pieces a shaft and a hex socket, not two sockets on the shafts. Lol sometimes I’m not the sharpest bulb on the wall
