Specific coatings offer additional characteristics and benefits to Tubtara® blind rivet nuts.
Since most Tubtara® applications are still in steel, corrosion resistance is often linked to surface treatment. Dejond's high-quality standard finish is called Zinktop 480 h. This electrolytic, Cr6+-free plating guarantees 480 h resistance against red rust. This strong corrosion protection offers very good internal thread plating which is critical for small diameters and closed-end parts. Excess plating weight in the thread, reduces the available space and subsequently blocks the bolt or screw.
