The World’s Most Reliable Blind Fastening System


The Huck Magna-Lok is a versatile, hole filling fastener that can be installed with conventional installation tools. It has a unique circle-lock feature, allowing a simple visual inspection to ensure it is installed properly, 100% of the time. Unlike competitive blind structural rivets, the Magna-Lok doesn't require a special nose-piece insert in order to be properly installed; the locking mechanism has been engineered into the fastener eliminating tooling and operator error. Magna-Lok is moisture-resistant, available in steel, stainless steel, 316 stainless steel or aluminum in diameters up to 1/2". With a large grip range, the Magna-Lok is the best gap-pulling fastener available, and provides a secure joint and is vibration resistant.
