baier & michels

baier & michels (b&m) is a German maker of fasteners, closing and sealing systems, and precision metal parts. Its head office is in Ober-Ramstadt, Germany. It is a member of the Würth Group. It makes parts by cold forming and machining.

The company began in 1932 as a local screw dealer. Two partners, a merchant and an engineer, set up the trading business in Frankfurt am Main. Over time it grew into a manufacturer with its own machine tools and storage areas. Today it has seven locations across Europe, North America and Asia, about 500 employees and revenue of 180 million euros. It makes about 165 million parts a year.

Its product range includes fasteners with built-in functions, such as the TRIMSCREW, which clears paint residue from threads. It also covers closing and sealing systems, such as the KL PLUG for bores with and without pressure. Direct screwing products form threads without cutting. They are made for metals, plastics, other materials and carbon fiber parts. The range also includes threaded inserts and bolts, rivet systems, turned parts, bearings and dampers. The HIGHLOAD screw is made for highly stressed joints in mixed-material designs.

b&m-ECCO TEC is its own chipless cold forming method. It makes long-shaft precision parts with complex profiles, such as ball studs, drive shafts and adjusting spindles. The company says it can produce them up to ten times faster and with less energy and material than turning.

b&m also offers engineering. It runs fastening tests in its laboratories, supports customers with application engineering and gives technical training. It makes products from coiled wire using headers and thread rollers, and it uses solar power from its own roofs.

Its customers work in automotive and vehicle making, household and garden appliances, electrical industry, renewable energy, construction, farm and forestry machines, automation and sensors, sports equipment and health technology.

The company ranks among the TOP 100 most innovative German mid-sized firms for 2025. It won the German Sustainability Award in the Resources field. It also holds an EcoVadis rating among the top 15 percent of metalworking firms.
