Round Head Copper Rivets 30mm Length

T-shaped solid copper rivets measuring 4 mm head diameter, 7 mm hat diameter, and 30 mm shank length — ideal for medium-thickness assemblies requiring robust, conductive, and visually harmonious fastening. Material is unalloyed copper with documented corrosion resistance and stable electrical resistivity (≤ 1.724 µΩ·cm). Cold-formed process enhances grain alignment and reduces porosity versus cast equivalents. Installation method relies on controlled plastic deformation of the shank — achievable with standard workshop tools — yielding joints resistant to vibration, thermal cycling and humidity. Used across electrical OEMs, architectural metal fabricators, educational STEM kits, and conservation studios working with historic copper alloys.
