In order to satisfy these needs, B.B. S.r.l. has set up a production strategy that aims to meet every customer’s needs. As far as screws are concerned, our warehouse is always well stocked with both finished and semi-finished products of different diameter and length in order to guarantee fast delivery times while, in terms of nuts, B.B. is mainly involved in the production of the DIN 69051/5 type to ensure interchangeability and virtually immediate availability. Right-hand helixes are standard; left-hand helixes can be machined on request.
