Pololu Universal Aluminum 6mm Mounting Hubs (4-40)

Review by Otto
General

The Pololu Universal Aluminum 6mm Mounting Hubs (4-40) is a stout design with the one flaw of the set screws proportions not enabling sufficient stability to maintain a secure fit.

Not that good....

Review by Brian
General

As other have said the set screws keep coming loose. I tried Loctite and CA to secure the set screws but finally the threads stripped on the hub. I am now using the 6mm Set Screw Hub (Product Code : RB-Nex-17) and they work great!!

Set screws come loose

Review by Jacob
General

The hubs are nice and light, but the set screws that hold to hub to the shafts keep coming loose. I think a long 4-40 set screw with a larger hex head would probably keep them tight, but from the factory they are weak.

Good, but not great mounts

Review by Ken
General

As others have pointed out, the set screw can get a bit loose, which is a problem. Some blue loc-tite helped, so I'd invest in a bottle of that. Also, the set screw uses a 0.05" allen key (included), which are easy to lose and not sold on this website. It's great that it's included, but It took a bit of searching to find replacements.

set screw reliability is shady

Ok, could be better

Review by Bill

I find these very convenient to put together, but that they tend to come loose after I have my bot running around for a while. I bought some Actobotics hubs which have a setscrew 3x the size which worked much better for me.

Great product!

Review by Frédéric

This is my second reorder! What I really like about them is how light and strong they are! The treads are good but just don't forget your 4-40 screws!

Very good quality!

Review by Frédéric

This is the second set I buy! Very strong and solid but most of all very light! Nice treads for the 4-40 screws! Well machined! I recommend strongly! Just don't forget to order your 4-40!

Nice hub!

Review by Kevin
General

Overall nice product. Received three longer screws (four have been better), they were great since my D-Shaft groove was deep. Two screws per shaft are great too for the solidity. Don't forget to buy 4-40 screws! If you assemble them on a round shaft, remember to file a flat spot on the shaft. It will be easier to remove the hubs.
