Unbrako

Unbrako and Durlok branded fasteners are manufactured to be stronger than other standard equivalent fasteners and are considered to be the strongest high tensile fastener available. They are manufactured according to their own specifications as presented in the Unbrako Engineering Guide though they also mostly conform to their equivalent DIN or ISO standard. Unbrako and Durlok fasteners are manufactured in Ireland and India. Westfield Fasteners are one of the only suppliers in the UK that offer Unbrako products in sub box quantities.
