Are you still troubled by these fastening pain points?

• Separately handling screws, flat washers and spring washers slows production, raises labor cost;
• Missing spring washers in tight spaces leads to loosening under vibration and frequent rework;
• Small washers get lost or dropped, causing downtime or damage to precision parts;
• Too many separate parts complicate BOM, increase inventory and management cost.

All these issues can be solved with one SEMS Combination Screw with Spring Washer.

SEMS screws are pre-assembled with screw + spring washer + flat washer in one piece. The spring washer delivers consistent elastic tension for anti-loosening, anti-vibration and anti-backlash performance, ideal for long-term vibration, temperature change and dynamic load conditions to stop loosening at source.

Key Applications of Spring Washer SEMS Screws

2. Automotive & TransportationUsed in interiors, seats, dashboards, motor brackets and chassis attachments exposed to constant vibration. Spring washers maintain preload, ensure safety and reduce after-sales repairs and noise complaints.
3. Machinery & AutomationSuitable for machine tools, robots, conveyors, cabinets and motor bases. Spring washers resist vibration and alternating loads, keep clamping force stable and cut maintenance downtime.
4. Furniture & Office EquipmentOffice chairs, metal frames, cabinets and hardware. Spring washers prevent loosening; flat washers protect surfaces. One-step installation boosts efficiency and durability.
5. Sheet Metal & General ManufacturingChassis, racks, aluminum frames and thin-wall parts. Spring washers lock securely; flat washers distribute pressure and protect surfaces from scratches or deformation, perfect for mass production lines.
