Satin Stainless Steel Hinges are precision-manufactured from high-quality stainless steel, measuring 102mm x 71.88mm, with a thickness of 3mm and a hinge shaft diameter of Φ12mm. Equipped with a reinforced latch design, the evenly distributed screw holes on both wings are Φ10mm in diameter and spaced 25.4mm apart, meeting standard installation specifications. The double-safety latch structure effectively prevents forced removal of the door leaf, enhancing overall anti-theft performance. They are particularly suitable for entrance doors, fire doors, and other applications requiring high security.
