I'm getting grub screws and i was wondering do i need the m4's or m3's. Ihave a tornado and i was just wonderin because i came across a post where somebody said m4's were to big.

m4's hold the wheels on

i guess i need m3's then because im need the screw for the joint cup

head to the hardware store and see what they have in stock. More than likely, they have what you need.

so like home depot or lowes

yes

its not going to be easy to find a metric nylon lock nut or a metric grub screw from a hardware store. your better off going to a hobbystore.

ok

If you have an Ace Hardware they should have them in stock, they carry all kinds of metric screws, that's where we send all of our local customers to the Ace hardware down the road.

i picked some up at a hobby store for $1.50 for 4. good deal i think

you cant beat that plus you gave the business to a hobby store!!!!!!!!!!!!!!!

yup. but now ive got to go get another part tonight . the bottom rim part that covers the clutch spring just kinda snapped and shattered.
