Combination screws, also known as SEMS fasteners, are pre-assembled integrated fasteners that permanently combine a screw with flat, spring or toothed washers via crimping. No on-site washer assembly needed, significantly improving efficiency and avoiding washer loss or misalignment. Key advantages include high efficiency, reliable locking and stable load distribution. Main types: 2-piece/3-piece, Phillips pan head/hex washer head, carbon steel/stainless steel. Sizes M2–M12, compliant with GB9074 and ISO 3506. Widely used in electronics, furniture, machinery, automotive and construction. Custom lengths, coatings, head types and thread-locking (e.g., adhesive) available for diverse applications.
