Metric Hex Nuts For Resistance Projection Welding

Metric hex nuts for resistance projection welding are sized in metric units and are specifically designed for resistance spot welding. During the welding process, the small protrusions will melt and bond with the metal. The suppliers of Xiaoguo® can provide free samples.

Product Description

Metric hex nuts for resistance projection welding have a hexagonal shape, which makes it convenient to use a wrench for tightening. On one side of the nut, there are several protruding small soldering points, while on the other side, there are standard metric threaded holes.

Product details

The metric resistance projection welding hex nuts have small protrusions at the bottom. When the welding electrodes press down, the current flows through these protrusions, instantly melting the protrusions and fusing the nut with the underlying metal plate. This process is fast and automated, and is highly suitable for large-scale production lines in the automotive or home appliance industries.

Metric hex nuts for resistance projection welding cover sizes such as M6, M8, and M10. The pitch (for example, 1.0 or 1.25) needs to match your bolts. The size of the hex nut (for instance, a hex nut for M6 is 10 millimeters) determines the required wrench for the subsequent step.

parameter of Metric hex nuts for resistance projection welding

For resistance projection welding, keep the surface clean when using metric hex nuts. Oil or rust can damage the weld. Ensure that the electrodes are aligned and in good shape. Damaged electrodes can lead to poor welding. Pay attention to "spatter" (spark flying), which usually indicates a setting error and the weld may not be secure.

Product features

Metric hex nuts for resistance projection welding provide greater torque when tightening or loosening bolts, ensuring smooth, easy operation without slipping. They also ensure neatly aligned weld points and even heat distribution during welding. They adhere tightly to the welded components, creating a secure connection.
