Speed. Stability. Strength. Combination Screws Redefined
Combination Screws (also known as SEMS screws)
come pre-assembled with washers, eliminating the need for manual washer placement during assembly:
Boost Assembly Efficiency:
With washers already integrated, these screws remove the need to handle separate components—reducing time, minimizing errors, and accelerating workflow.Vibration-Resistant Strength:
The built-in washer enhances joint stability under vibration, maintaining tight, reliable fastening even in dynamic environments.Increased Resistance and Reliability:
The fixed washer adds friction and mechanical resistance, resulting in a more secure fastening solution with long-term integrity.
These versatile fasteners are widely used across automotive, electronics, appliances, furniture, and construction sectors—trusted for boosting productivity and ensuring enduring performance
