Magna-Lok

The HUCKLOK™ Fastening System

HuckLok™, with shear ring and lock groove, offers up to 1/4 in. grip and eliminates most pull-throughs when joining thin or lightweight materials, such as plastics, composites, and pliable metals. Double locking system secures connection. When used with Huck AK275 or 2025 tools, or any other blind riveting tool of proper pull capacity, HuckLok blind rivets install in seconds.
