S-90895A007 0.146" ID x 0.236" OD Heavy-Vibration-Resistant Spring Lock Washers for Socket Head Screws

Key Features & Benefits at a Glance

• Superior vibration resistance through dual top and bottom serration that bites into mating surfaces to prevent loosening under dynamic loads
• Exceptional corrosion resistance provided by 18-8 stainless steel construction, ideal for harsh industrial environments
• Optimized dimensional compatibility with both inch (#6) and metric (M3.5) screw sizes for versatile application across equipment
• Enhanced durability with Rockwell C38 hardness rating that maintains locking performance through repeated compression cycles
• Reliable compliance with RoHS 3 and REACH environmental standards for global manufacturing applications
• Precise fitment with 0.146" ID and 0.236" OD ensuring proper seating and distribution of clamping force
• Consistent spring action from 0.018" thickness and 0.035" overall height providing maintained tension in assembled joints

Professional Applications & Engineering Value

This spring lock washer addresses critical vibration-induced fastener failure in industrial equipment through its dual serration design on both top and bottom surfaces. The 18-8 stainless steel construction provides excellent corrosion resistance for applications in manufacturing, automotive, and outdoor equipment where environmental exposure is a concern. The Rockwell C38 hardness ensures the serrations maintain their biting capability through repeated compression cycles, while the precise dimensions (0.146" ID) guarantee proper fitment on both #6 and M3.5 fasteners. This combination of features makes it particularly valuable for vibration-resistant fastening in machinery, electrical enclosures, and assembly lines where reliable locking performance is essential for operational safety and reduced maintenance intervals.
