DIN and OEM hex flange bolts combine a washer-style flange with high-strength Class 10.9 alloy steel for demanding applications. Available in zinc-plated and zinc-flake finishes, as well as stainless-steel variants, they distribute load evenly and resist loosening. Rare thread sizes - such as M15Ć1.5 and M14Ć1.25 - support precise fit and long-term durability.
