A casement fastener is a vital piece of window hardware that combines functionality, durability, and design. Commonly used on side-hinged windows, a casement fastener helps to keep windows securely closed or slightly open for ventilation. While it may seem like a small detail, this simple component plays an important role in maintaining both the safety and aesthetic appeal of your home. What Is a Casement Fastener? A casement fastener is a latch mechanism fitted on casement windows — the type that opens outward on side hinges. It typically consists of a handle that locks into a catch plate or keep, holding the window tightly shut. Some casement fasteners also include a locking feature with a key for extra security, making them ideal for ground-floor or accessible windows. These fasteners are made from various durable materials such as brass, wrought iron, stainless steel, or bronze, ensuring long-lasting performance and resistance to corrosion.
