Product: Striped Conical Spring Lock Washer (Sizes M3–M16) — Stainless Steel A2 and 65Mn Carbon Steel Key benefits - Prevents loosening under vibration: the conical, striped design maintains axial tension and resists back-off in dynamic applications. - Positive mechanical lock: when fully tightened, the washer’s groove edges engage the nut and the mating material surface, producing a secure bite that reduces the risk of nut rotation. - High durability options: available in corrosion-resistant Stainless Steel A2 and high-strength 65Mn carbon steel for strong spring action and repeated use. - Easy sizing and compatibility: fits standard metric fasteners in sizes M3, M4, M5, M6, M8, M10, M12, and M16. Features - Type: 65Mn Carbon Steel Type available; also produced in Stainless Steel A2. - Form: Striped conical spring (spring lock) washer designed to combine spring force and serrated/grooved locking edges. - Materials: Stainless Steel A2 for corrosion resistance; 65Mn Carbon Steel for superior spring performance and hardness. - Function: Groove edges on the washer bite into the nut and the clamped surface when tightened, creating a reliable locking action. Performance and suitability - Reliable under vibration and cyclic loads due to conical spring action that maintains clamping force. - 65Mn Carbon Steel variant provides strong elastic recovery and wear resistance for repeated assembly/disassembly. - Stainless Steel A2 variant is suitable where corrosion resistance is required. Applications / Use scenarios - Automotive components: secures nuts and bolts in engine mounts, suspension brackets, and other areas subject to vibration. - Machinery and industrial equipment: locks fasteners on conveyors, motors, and gearboxes to reduce maintenance and downtime. - Structural and assembly work: used in metal frames, panels, and equipment housings where a dependable locking washer is needed to prevent loosening. What to expect when using this product - Select the washer material based on environment and load: choose Stainless Steel A2 for corrosive or outdoor environments, and 65Mn Carbon Steel where higher spring strength is required. - Match the washer size to the bolt/nut size (M3–M16) for correct fit and locking performance. - Tighten the nut fully: the washer’s groove edges will engage both the nut and the mating surface to provide the intended locking action.
