About DENKER Verbindungstechnik
DENKER Verbindungstechnik GmbH & Co. KG, based in Plettenberg, is a manufacturer of standard-compliant screws and fasteners as well as parts made to individual customer specifications. The company is the successor of Juma Qualitätsschrauben GmbH & Co. KG and has been producing fasteners since the late 1970s, with over 30 years of experience in cold forming. The product range includes sheet metal screws, metric screws, screws for plastics, special screws and drawing parts, as well as cold-formed parts and multi-stage parts such as pins and rivets. Production is carried out on process-monitored double-strike presses, two-die three-blow presses and multi-stage presses, various thread rolling machines as well as pointing and notching machines. The materials include steel in grades 4.8 to 12.9, stainless steel, brass, aluminium and copper. In addition, surface treatments, secondary finishing operations and, on request, automatic 100% inspection and camera sorting are offered.
