S-90483A174 25 mm ID x 44 mm OD DIN 125; ISO 7089 General Purpose Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc yellow-chromate plating, extending service life in harsh industrial environments
• Exceptional load distribution due to precise 44mm OD and 3.7-4.3mm thickness, preventing surface damage and joint loosening
• Reliable hardness performance with Rockwell C38 rating, ensuring dimensional stability under high-pressure applications
• Guaranteed interchangeability through compliance with DIN 125 and ISO 7089 standards for M24 screw sizes
• Environmental compliance assurance with RoHS 3 and REACH adherence, meeting global regulatory requirements
• Optimized metric sizing with 25mm ID for perfect fit with M24 fasteners, reducing installation errors
• Enhanced durability from plated steel construction, providing long-term reliability in heavy-duty assemblies

Professional Applications & Engineering Value

This M24 flat washer delivers critical engineering solutions where corrosion resistance and load distribution are paramount. The zinc yellow-chromate plated steel construction effectively combats oxidation in outdoor, chemical, or high-moisture settings, preventing fastener failure. Its precise metric dimensions (25mm ID, 44mm OD) ensure uniform pressure dispersion across M24 bolted joints, eliminating stress concentrations that cause material deformation. Commonly specified in heavy machinery, structural steelwork, and industrial equipment assemblies, this DIN 125 / ISO 7089 compliant washer maintains joint integrity under dynamic loads and vibration. The hardened Rockwell C38 material withstands repeated torque applications without deformation, making it ideal for maintenance-critical applications where disassembly reliability is essential.
