Alcoa launches high strength structural blind fastener

1 min read

Alcoa Fastening Systems & Rings has launched a 12.7mm diameter Huck Magna-Lok structural blind fastener.

The large diameter fastener is described as having 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,” states Alcoa. “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 lighter weight 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 12.7mm diameter Magna-Lok fastener has been approved by the widely recognised Deutsches Institut für Bautechnik (DIBt).

“Customers looking to improve their assembly processes, and in particular the construction industry, can greatly benefit from the high shear and tensile strength of the new 12.7mm diameter Magna-Lok fastener”, said Joël Melquiot, AFSR product manager for Huck and Marson brands. “We also see many applications for this product in the commercial transportation, green energy and agriculture markets due to the high resistance to joint failure.”
