S-91812A790 1" ID x 1.54" OD Extreme-Vibration-Resistant Wedge Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through dual-sided serrations that bite into mating surfaces, preventing loosening under extreme dynamic loads
• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments including marine and chemical applications
• Enhanced durability and wear resistance from case hardening to Rockwell C51 hardness, extending service life in high-stress applications
• Precise metric sizing compatibility with M24 screws and 1" ID/1.54" OD dimensions, ensuring perfect fit in international engineering projects
• Reliable locking performance with wedge lock design that maintains clamping force better than standard washers
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global industrial use without regulatory concerns
• Consistent thickness control between 0.120-0.140" for uniform pressure distribution and reliable joint integrity

Professional Applications & Engineering Value

This M24 wedge lock washer addresses critical engineering challenges in vibration-prone applications where fastener failure can lead to equipment damage or safety hazards. The 316 stainless steel construction provides superior corrosion resistance compared to standard grades, making it ideal for offshore platforms, chemical processing equipment, and marine applications where saltwater exposure is common. The top and bottom serration design creates multiple biting edges that dig into both the fastener and workpiece, creating mechanical interference that resists rotational forces and maintains clamp load under continuous vibration. The case hardened treatment to Rockwell C51 ensures the serrations maintain their sharpness and locking capability through repeated installation cycles, while the precise metric dimensions guarantee compatibility with M24 screw assemblies in heavy machinery, structural steel connections, and industrial equipment requiring reliable, maintenance-free performance.
