Stud Bolts
From standard to custom-engineered solutions — all from a single source.
For precise, detachable connections — ideal for use in steel, cast iron, aluminum alloys, and light metal applications. Graewe offers a complete range of stud bolts in accordance with DIN 835, DIN 938, and DIN 939, in strength grades 5.8, 8.8, 10.9, A2-70, and A4-70 — from M6 to M24 in all standard dimensions, directly available from stock. Our production program extends up to M56, including customer-specific designs based on drawings or samples.
Stud bolts are cylindrical fastening elements with external threads on both ends and an unthreaded center section. They enable precisely aligned, detachable connections. The screw-in thread provides a secure fit in the base material, while assembly and disassembly take place via the nut end — ideal for applications requiring repeatable fastening operations. Typical applications include mechanical engineering, pressure vessel and apparatus construction, and flange joints. Graewe is an approved manufacturer according to AD Specification W0 and listed in VdTÜV Bulletin 1253/4.
