Brass Casement Fasteners

Brass Casement Fasteners are an essential component for securing traditional casement windows, which open outwards like a door from side hinges. Perfectly suited for period-style homes—whether Victorian, Federation, Edwardian or Art Deco—our collection of fasteners blends timeless style with practical functionality.

At Restoration Online, we offer a wide range of solid brass hardware, with our casement fasteners available in various finishes to suit your décor. Each fastener is installed on the vertical timber section of your window frame and is typically reversible, making installation straightforward regardless of hinge placement.

Many of our fasteners include both a cranked and flat keeper to suit different window configurations—whether the sash sits flush or perpendicular to the frame. For those seeking additional peace of mind, we also offer lockable casement fasteners, secured with either a key or grub screw. Select models even feature night vent functionality, allowing you to safely lock the window in one of two open positions for airflow without compromising on security.

For a cohesive finish, we recommend pairing your fasteners with matching casement stays. We also supply adaptor plates, ideal for older timber windows that don’t close flush, ensuring your fastener sits neatly and operates smoothly.

Whether you're restoring a period property or designing a new build with classic charm or a Hamptons influence, our extensive hardware range—including over 20,000 quality products—offers timeless solutions tailored to your home's unique character.
