DIN 6791:2011 Pan Head Semi-Tubular Rivet

DIN 6791:2011 Pan Head Semi-Tubular Rivet features a pan head semi-tubular rivet structure, making it suitable for joints that require lower setting force while maintaining head-side clamping.

The semi-tubular end flares more easily during riveting and is suitable for thin sheets or softer materials; the pan head provides a broad bearing surface to protect the workpiece. This structure supports efficient assembly while balancing joint stability, load distribution, and convenient maintenance, making it practical for standardized purchasing and volume production.

This product can be used in electronic housings, hardware fittings, toys, light brackets, and furniture accessories. Tubular depth, material, plating, and head size can be selected to meet requirements for corrosion protection, wear resistance, assembly efficiency, and long-term reliability.
