Alcoa Introduces High Strength 12.7mm Diameter Huck® Magna-Lok® Fastener

Alcoa has launched its new 12.7mm diameter Huck Magna-Lok structural blind fastener. The company believes this is the strongest product of its type.

The large diameter 12.7mm Magna-Lok fastener has extremely high shear (44.4Kn) and tensile (31.1Kn) strengths, plus high resistance to joint failure. It offers 60% and 57% respective increases in shear and tensile strengths when compared to its predecessor, the R12 9.5mm fastener. The higher strength capability provides the user with the option of installing fewer fasteners per application, thus facilitating a reduced inventory, faster production times and potentially resulting in more lightweight products.

In addition to its high strength, the new product has all of the features of the standard Magna-Lok blind fastener, including a wide grip range to accommodate large variations in joint thickness, and 360° internal locking technology, which enables the pin to be mechanically locked to the sleeve. Its expansion during installation also provides excellent joint tightness and high-quality resistance to liquid penetration. The new fastener has been approved by the widely recognised Deutsches Institut für Bautechnik (DIBt).
