About L. Künzel Nagelfabrik
L. Künzel Nagelfabrik GmbH is a German fastening technology manufacturer with over 300 years of nail-making tradition in Arzberg, dating back to master nailsmith Johann Lorenz Künzel (born 1782). Production takes place at the company's own site in Weißenfels, where industrial nails are manufactured in all common magazine formats – from coil nails, strip nails and roofing felt pins to screws, pins, brads, staples and special fasteners. The materials include steel, zinc-plated and hot-dip galvanized steel, stainless steel (V2A) and black phosphated versions; polymer fasteners made of plastic are also offered. The product range is aimed at continuous industrial operation in series production as well as pallet and packaging lines and the craft construction and carpentry trades. In addition to its own products, the company distributes equipment and accessories from leading manufacturers such as MAX, Omer, Kihlberg, HiKOKI and Milwaukee and offers consulting on high-pressure technology, plastic fasteners and automation. An in-house repair service with a large spare parts warehouse complements the range. The offices and warehouses are heated with biomass, and the electricity comes 100 % from renewable energies.
