DIN 929 hexagon weld nuts have three equally spaced welding projections for solid contact with the weld surface.
Slotted nuts mainly refer to hexagonal slotted nuts, that is, a slot is machined above the hexagonal nut. It is used in conjunction with a bolt with a hole in the screw and a split pin to prevent the bolt from rotating relative to the nut.
The function of the hexagonal slotted nut is to fix the front and rear axles of the vehicle by tightening the screws through the front and rear wheel axles, so that the frame and the tires are fixed together.
The Grade 12.9 Hex Head Bolts specification exceeds the standard 10.9 grade bolts.
