Structural blind fastener offers high shear and tensile strength

16 January 2016

Alcoa Fastening Systems & Rings has introduced 12.7mm diameter Huck Magna-Lok structural blind fastener, which it claims is the strongest product of its type available.

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 percent respective increases in shear and tensile strengths when compared to its predecessor, the R12 9.5mm fastener.

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 good joint tightness and resistance to liquid penetration.
