I recently purchased the 60mm Mecanum Wheel Set 14159 and four 6mm Aluminum Mounting Hub for 60mm Mecanum Wheel 18021. The 14159 package did come with the 3 long screws per wheel but my robot students lost some of them and their nylon lock nuts. What size are the long screws so that we can mount the hubs to the wheels? A packaging list on the Set 14159 would be helpful. I assumed they were 4-40 x 1 1/2" since #6-32 screws are slightly to big in diameter. However, i cannot find any 4-40 screws longer than 1" on the robotshop website and i know the existing “short” screws for the wheels are at least 1 1/4" long.

Hi,
The size of the long screws is M3x40.
Unfortunately, I don’t think there is any in the catalog.
Let me know when you have bought the part and if you have bought it with RobotShop so I can verify with the manufacturer if they can provide some replacement.
