screw of choice for engineers in the US and Britain. After World

Applications
UNBRAKO socket screws, the most widely recognized fastener brand
name in the world, are used in machine tools, tools and dies, earth
moving and mining machinery, and a wide range of industrial and
engineering applications. Sold through technically qualified stocking
distributors, UNBRAKO socket screws are high-strength fasteners
certified by Unbrako to meet or exceed industry standards. For example,
UNBRAKO socket head cap screws are 10,000 psi (100 Mpa) above industry
standards and most competitive products.
Innovation
Unbrako, the world leader in supplying high-strength socket screws,
continues to innovate. The most recent example is the addition of
E-CODE, the unique "traceability on the head system."
Traditional traceability ends with the packaging label, but Unbrako's
E-CODE has the individual lot traceability stamped on the head.
