Hammer nuts type B for aluminium profile 20x20

Hammer nuts are used in aluminium profiles type 20x20 with 6mm slot. Hammer nuts type B are very practical because they can be used even when the assembly of the structure is finished. Their shape allows them to fit easily into the slot of the 20x20 aluminium profiles and then they lock when tightened. They are sold in sets of 10 pieces and are available in 3 sizes: M3 / M4 and M5.
