Nut for welding DIN 929 M4

Product detailed description

The hexagonal weld nut according to DIN 929 and ČSN 021455 is intended for permanent threaded connections that require a firm and reliable attachment to a metal substrate. This nut is made of steel of strength class 5, which guarantees its sufficient resistance to mechanical stress. The nut is supplied without surface treatment, which is suitable for applications where additional corrosion protection is not required or where surface treatment will be applied after welding.

The nut has a metric M4 thread with a pitch of 0.70 mm, which is a standard size for this type of fastener. The thread diameter is M4, with an outer diameter d1 of 6 mm. The width of the nut between the opposing surfaces (s) is 9 mm, while the width e, measured between the diagonals, is 9.8 mm. The height of the nut (h) is 0.35 mm, while the total height including the welding lugs (h1) is 0.65 mm. The width b, which can refer to the width of the welding lugs, is 0.8 mm.

The nut is equipped with three welding lugs, which ensure a strong connection to the metal substrate during welding. This design allows for efficient heat distribution and ensures stability during the welding process. Due to its design features, this nut is ideal for use in various industrial applications where a strong and permanent connection is required.
