About us

The globally focused b&m Group, with its headquarters in Ober-Ramstadt in southern Hesse, has built up a strong position as an innovative partner to the manufacturing industry in the field of cold forming.

The basis for this is provided by high-quality fasteners as well as closing and sealing systems from our own development and production. Our customers include OEMs and suppliers from the automotive, electrical and medical technology sectors.

baier & michels reliably supports them not only as a producer, but also as a problem solver: Besides technical application advice and connection tests in our laboratories, we also provide specialist training and a unique standardization tool that industrial companies can use to massively reduce the variety of their C-parts.

Our 500 employees are our most valuable asset. With their know-how and experience, we are always able to meet the highest demands of our customers. You can count on it!

b&m-KL PLUG®

The b&m-KL PLUG® is a one-piece and universally applicable closing and sealing element for holes with and without pressure load. Due to the different materials and diameter ranges, it can be adapted to different customer applications and can seal up to 30 bar operating pressure. The element offers simple and efficient assembly without waste generation and also offers a number of other advantages over conventional closing and sealing systems for holes.

Various options for the placement of the b&m-KL PLUG®


The b&m-TRIMNUT® turns the thread-forming principle upside down. In this case, it is not the screw but the nut that is both the fastener and the thread-forming tool. Designed to remove weld spatter on welding studs or coating residues, the b&m-TRIMNUT® is also capable of forming a thread in conjunction with a corresponding bolt geometry.
