Synonymous with the history of Unbrako Group, the Unbrako brand is over 80 years
old and remains the socket screw by which all others are measured. Developed in the
1920s, it rapidly became the socket screw of choice for engineers in the US and
Britain. After World War II, the product spread to all worldwide markets and today
is recognized as the brand and performance leader in over 25 industrialized countries.
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.
Today, Unbrako, as part of the Unbrako Fastener Group
and a 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.
