Window Fasteners

Shop traditional window fasteners for timber casement windows. Our range includes practical and decorative fittings designed to secure your window when closed, while complementing the character of period properties and traditional homes.

Choose from classic casement window fasteners, including Monkeytail, Pear Drop and Shepherd’s Crook styles, alongside locking and night-vent designs. Pair your fastener with matching window furniture for a coordinated finish.

Casement Window Fasteners

A window fastener secures a compatible casement window in its closed position. It is commonly fitted with a matching keep or plate and is often paired with a window stay, which supports the window when open.

Our traditional window fasteners are suitable for timber casement windows and are available in a range of styles, materials and finishes.

Traditional Window Fastener Styles

Choose a design that suits your property and existing hardware. Monkeytail fasteners create a distinctive traditional look, Pear Drop designs offer a simple period detail, and Shepherd’s Crook fasteners provide a more decorative finish.

Our range also includes Ball End, Spoon End, wedge and reeded designs, making it easier to coordinate your fittings throughout the home.

Locking and Night-Vent Fasteners

For added security, choose from locking casement window fasteners. Night-vent fasteners can allow a compatible window to remain partially open for ventilation while still being secured.

Always check the individual product description to confirm the fitting type, handing, dimensions and window compatibility before ordering.

Choosing the Right Window Fastener

Before choosing your fastener, consider:

  • The type and construction of your timber window
  • Whether you need a locking or non-locking design
  • The required handing and fixing arrangement
  • The style of your existing window stays and handles
  • The finish that best suits your property
