The Huck Magna-Bulb® is a unique, clamp-type fastener offering high shear strength in specific applications.  Its bulbing action during installation spreads the load over more surface area, supplying a stronger, longer-lasting connection. This increased bearing area makes Magna-Bulb ideal for pull-out resistance in thin materials, and oversized or misaligned holes.
