10 Pcs Eccentric Spacers 5mm Bore for V Wheel Aluminium Extrusion 3D Printer

Inexpensive alternative to the high-dollar Openbuilds 6mm eccentric spacers. Those I received are all appx. 8.54mm overall, 6mm of which protrudes after install, with a 7.12mm OD shank, and are stainless steel. A 5mm black oxide fastener just clears ID for a snug fit. The eccentric orientation is marked on the exterior with a line that is easier to see than a tiny dot. I will definitely purchase these again - even if OB's price came down to this level. A++

These will work fine. But I had bought these with the pack of 10 idler wheels(they show them being bought together) thinking that they would work together. Well they will not work together. The wheels have a 5mm bore as these have a 5 mm bore. But you need a 7mm id bearing in order for them to work together. So the wheels I got are useless.

Works as advertised, some pieces cam a bit rusty, easy to clean up but still dont want to get new parts which are rusty. Would have given 5 stars if they were all clean. Will buy again when needed.

Using on a project I'm building.Size is as noted in the pictures and description.They work well.

Nicest maching eccentric nuts I have ordered

The item sent was 6mm not 6.3mm like stated so I cant use them in my build. You may think that .3mm is nothing but it is huge when it comes to the accuracy of a CnC or 3d printer

Parts arrived rusty. Baggy was even rust colored. I expected better than this at over $1.00 a piece.

Every nut was either 8.5mm or greater. A small discrepancy is understandable but labeling then as 6.35mm when they are clearly selling 8.5mm nuts is just false advertising.
