Head Screws
Headscrews — Made in Europe. Standardized or customized. Direct from Graewe.
Head screws are fasteners with a shaped head that transfers torque from the tool to the screw. Whether hex head, flange head, cylinder head, or twelve-point, each geometry is tailored to your technical requirements and manufactured in accordance with international DIN and ISO standards. Graewe head screws are produced entirely in Europe and are available both as standard versions and according to your drawings or specifications — in a wide range of variants and strength classes, including high-strength grades 8.8,10.9, and 12.9.
Graewe head screws are known for precise manufacturing and dimensional consistency. They are available in a variety of materials and surface finishes, suitable for both permanent and detachable joints — even under mechanical or thermal loads. We supply screws with zinc-flake or MK coating completely from a single source— ensuring optimal corrosion protection and reliability. Typical areas of application: mechanical engineering, plant engineering, steel construction, vehicle manufacturing, and other industrial sectors.
