Retaining all the features of the standard version of the Magna-Lok structural blind fastener; including a wide grip range to accommodate large variations in joint thickness, 360 internal locking technology enabling the pin to be mechanically locked to the sleeve, expansion during installation for excellent joint tightness and high-quality resistance to liquid penetration; the 316 A4 stainless steel Magna-Lok fastener also offers corrosion resistance beyond anything else in the Huck blind fastener range.

Known as ‘marine grade’ due to its preferred use in the construction of boats, ships, oil and gas rigs, and off-shore wind farm towers, 316 is an austenite stainless steel which contains 18 percent chromium and 12 percent nickel.  Steel is considered stainless when its chromium content is at a minimum of 10.5 per cent. Therefore, a higher content will result in an enhanced corrosion resistance. Unreactive chromium III oxide can form on a component's surface, protecting the metal beneath from the environment. Nickel further increases the corrosion resistance of the resultant alloy.

Andrew Smith, engineering manager at AFS, said: “Magna-Lok is the most popular and versatile of our structural blind fasteners. Combined with the demand from our customers for a high-performance corrosion-resistant fastener, it was the obvious choice on which to develop a 316 stainless steel version. In addition to offshore applications, we are also looking at its use in food processing machinery, heat exchangers, chemical storage facilities and medical equipment.”
