Professional Applications & Engineering Value
Engineered for demanding industrial fastening applications, this zinc-plated steel flat washer solves critical challenges in machinery assembly, structural steelwork, and heavy equipment manufacturing. The DIN 7349 specification guarantees dimensional precision that eliminates misalignment issues with M22 screws, while the Rockwell B76 hardness prevents deformation under extreme vibration and load conditions. The zinc-plated surface treatment creates an effective barrier against rust and chemical exposure, making these metric flat washers ideal for automotive, construction, and marine environments where corrosion resistance is paramount. The generous 50mm OD distributes clamping force over a wider area, protecting soft materials and reducing stress concentration points in critical joints.
Specification Summary & Compliance
This heavy-duty flat washer features precise metric dimensions (23mm ID × 50mm OD) with thickness tolerance of 7.0-9.0mm, manufactured to DIN 7349 standards for guaranteed dimensional accuracy and performance. The zinc-plated steel construction with Rockwell B76 hardness ensures consistent mechanical properties. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety requirements for industrial components.
