Engineered with a double-layer self-locking design to create irreversible friction, ensuring bolts stay securely tightened even under extreme vibration, heavy loads, or thermal expansion.
Choose between corrosion-resistant stainless steel for harsh outdoor/chemical conditions or Dacromet-coated 65Mn steel for superior rustproofing and 500% longer fatigue life compared to standard washers.
Covers 98% of industrial fastener needs, from small precision equipment (1/4) to heavy-duty construction machinery (2inch), eliminating the hassle of sourcing multiple washer types.
Conical shape enhances elastic preload distribution, absorbing shocks and compensating for material relaxation to maintain tension 3x longer than flat washers.
DIN25201 standards, trusted for automotive drivetrains, CNC machine bases, bridge bolt connections, and high-speed rail track fastening systems.
