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’, 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.

Non-reactive 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.
