Five Eighth Inch Belleville Self Locking Washers For Automotive Equipment
✔️ Double-layer self-locking design; stainless or Dacromet coated options; single piece
These Belleville washers are a double-layer self-locking locking washer designed for automotive, industrial equipment, and construction gear. They resist loosening under vibration and temperature changes, with two coating options: corrosion-resistant stainless steel or Dacromet-coated 65Mn steel for superior rust resistance and up to 500% longer fatigue life. They cover bolt sizes from M3 to M56 per DIN25201, making them ideal for automotive drivetrains, CNC machine bases, bridge bolt connections, rail track fastening, and linear slide unit assemblies.
Key specs
✅ Durable double-layer self-locking design creates irreversible friction, preventing loosening under vibration✅ Choose stainless steel or Dacromet-coated 65Mn steel for rust resistance and up to 500% longer fatigue life
✅ Wide size range M3 to M56 (5/8 inch sizing) covers most fasteners
✅ Conical shape distributes preload evenly and absorbs shocks, maintaining tension longer
✅ DIN25201 standard supports automotive drivetrains, CNC bases, bridge bolts, rail tracks
💡 What is a Belleville washer used for in high vibration machinery and how does it work? Belleville washers act as a preloaded spring to keep joints tight under dynamic loads. - Handy for automotive drivetrains and CNC bases - Maintains tension through thermal expansion and material relaxation - Helps distribute load evenly and absorb shocks
