GB/T 12615 Mushroom Head Break Mandrel Closed-End Blind Rivets – Strong, Sealed Fastening Solution

Description

The GB/T 12615 Mushroom Head Break Mandrel Closed-End Blind Rivets offer an optimal fastening solution for demanding applications requiring both secure holding power and moisture-resistant sealing. These rivets are blind type, meaning they can be installed from one side of the workpiece, making them ideal for enclosed or limited-access areas.

The mushroom head design provides a broader clamping surface, making them suitable for use on softer materials without pull-through. The closed-end structure prevents the passage of fluids, gases, and contaminants, ensuring enhanced performance in electrical, automotive, HVAC, and industrial installations.

Available in carbon steel and stainless steel with various surface finishes, these rivets meet international standards such as GB, DIN, ISO, ANSI/ASTM, BS, and JIS. We also offer OEM manufacturing based on custom drawings or sample requirements. Free samples are available for evaluation.
