Stainless Steel Spring Lock Washer

Stainless steel spring washers are manufactured from high-quality stainless steel and offer excellent elasticity and fatigue resistance. Once installed, the washers generate continuous elastic force, increasing friction at the contact surface and effectively preventing threaded connections from loosening in environments subject to vibration or impact.

• Stainless steel construction, rust-proof and corrosion-resistant: Made from 304/316 stainless steel, these fasteners do not rust and are suitable for humid, outdoor, food processing, chemical, and marine environments.
• Elastic anti-loosening design, reliable locking: Utilizes its own elasticity to compensate for thread play, effectively preventing bolts and nuts from loosening due to vibration.
• Standard sizes, high versatility: Complies with DIN and national standards, perfectly compatible with various stainless steel bolts and nuts.
• Easy Installation, Low Cost: Compact and easy to install, making them the most commonly used anti-loosening components for machinery, equipment, and piping.
• Complete Range of Sizes, Available in Bulk: Full range of standard sizes from M2 to M24, with support for full-case wholesale export.

• Anti-loosening for mechanical equipment, motors, fans, and pump housings
• Food processing machinery, medical devices, and water treatment equipment
• Marine vessels, offshore engineering, and coastal facilities (316)
• Solar panel mounts, curtain walls, guardrails, and outdoor facilities
• Instruments and meters, electronic enclosures, and piping valves

1. Before installation, clean any oil or rust from the surfaces of the parts to be connected using alcohol or a cleaning agent to ensure good contact between the washer and the surface, thereby preventing any compromise to the anti-loosening effect.

2. When selecting a washer, verify the bolt specifications to ensure the washer's inner diameter is slightly larger than the bolt's diameter, and its outer diameter covers the edges of the bolt hole to prevent tilting or warping.

3. When tightening bolts, use a torque wrench and apply the torque value corresponding to the bolt grade to avoid over-tightening, which can cause the washer to deform or fail.

4. When using on hard surfaces, install a flat washer beneath the spring washer to prevent sharp edges from damaging the connected components. In high-temperature environments, prioritize materials such as 316 or higher.

5. Inspect the condition of the spring washers regularly. If the opening has noticeably widened, cracks are present, or the washer cannot return to its original shape, replace it promptly to ensure connection safety.
