Established in 1911, Unbrako is the world leader in advancing the technology of bolted joints and meeting the needs of industry for stronger and better performing fasteners. Unbrako products have higher tensile strength, improved fatigue resistance and extended life cycle.[Unbrako warehouse In Melbourne]

[Unbrako Warehouse In Los Angeles]The famous Unbrako socket head cap screw and the self-locking Durlok fasteners are the solutions of choice for engineering applications across the globe, and hold together the Melbourne AAMI Park, Heathrow T5, Delhi Metro, to name a few.

The first development of an internal-wrenching hexagon drive of which there are records is that of circa 1911 in Pennsylvania, by the founders of Unbrako. One could say that Unbrako invented the World’s First Internal Hexagon Socket Screw.

It is today used by industries such as the automotive, power generation, petrochemical, heavy machinery, railway, mining, shipping, wind energy, infrastructure and military sectors.

Unbrako was acquired by the Deepak Fasteners Group in 2008 and has since grown multi-fold with new warehouse facilities in Birmigham (UK), Los Angeles (USA) and Brisbane (Australia). Further a $100 million has been made in the new state-of-the-art manufacturing plant in Bhopal.
