A pack of 20 Pieces of Square Nuts (Nut size: M6).
These nuts are ideal for Eco racks. These are made of steel with galvanized surface and silver colour.
Dimensions: Height 3.72 mm, Width 10.78 mm, Length 10.78 mm. Weight: 0,003 kg.
These are the standard square nuts for Eco racks and I used these to build my rack and wherever needs to use M6 screws.
Good quality and value for that money.
I recommend these.
