The company combines the tradition of its founder Anton Blaj with the newest, most sophisticated engineering developments and innovations. Since 2004, the company is managed by his daughter, Petra Blaj, Master of Economics, who has always taken an interest in the family business: “I always wondered how I could transfer various skills that I acquired into our company, which was not easy. After I finished my studies, I began working in the company’s finance department. During all this time, I have completed additional training to support the growth of the company. I assumed the role of Director when the company was reincorporated in 2014, however, I still consult with my father before making any key decisions.


  • 1966


    The tradition of the Blaj family company reaches back half a century. In 1966, Anton Blaj, an electric engineer, set out to manufacture bolts. In the mid-1990s he launched the sole proprietorship ANTON BLAJ, s. p., and expanded the production of standard bolts from the local market to the international market
  • 2000


    Our company continued to manufacture standard bolts under other brand names, for wholesalers and end customers, and in the process acquired valuable experience and know-how. The transition into the new millennium was marked by major investment in technology, equipment and training of staff. We set up a new quality strategy. At the same time, we obtained the AD 2000 Merkblatt certificate and achieved a breakthrough in the production of high-end bolts.
  • 2013


    In the following years, we purchased a tensile testing machine, set up an in-house laboratory and started to issue certificates. In cooperation with research organisations, we renovated our hot forging bolt production process and actively entered the market of custom-made bolts and machinery construction. In 2013, one of our major customers honoured us with a quality award.
  • 2014


    A year later, we reincorporated as a limited liability company and Anton’s daughter Petra, Master of Economics, took over as manager. This period was also marked by a number of investments in automation, robotic process automation, control equipment and staff training – in line with our vision to become a leading European manufacturer of special, dynamic load carrying fasteners.
