Flush Bolts

View our extensive collection of flush bolts, designed to provide discreet, reliable security for a wide range of internal and external door applications. Also known as door flush bolts or flush door bolts, these practical pieces of architectural ironmongery are designed to sit neatly within the edge or face of a door, providing secure fixing without the bulky appearance of traditional surface bolts.

A flush bolt operates by sliding vertically into the door frame, head or threshold, helping to hold one door leaf securely in position. This makes flush bolts particularly useful for double doors, French doors, paired doors and internal room dividers, where one door leaf needs to be secured while the other remains operational.

Flush Bolts for Double and French Doors

Flush bolts for double doors are a popular choice where a clean and unobtrusive finish is required. When fitted correctly, the bolt mechanism is largely concealed within the door, creating a streamlined appearance that works particularly well with modern and traditional door designs.

For French doors, flush bolts can be installed to secure the inactive door leaf at the top and bottom of the frame. This allows the active door to open and close normally while keeping the second leaf firmly secured when the doors are closed.

Internal Door Flush Bolts

Internal door flush bolts are ideal for applications where discreet security and neat aesthetics are important. They can be used on a variety of internal doors, including glazed doors, timber doors, double doors and room dividers.

Because the mechanism is designed to sit flush with the door, these fittings are an excellent option for homeowners, joiners and installers looking to avoid protruding hardware. They can also be coordinated with other door furniture and architectural ironmongery, including door handles, hinges, locks and latches.

Choosing the Right Door Flush Bolt

When selecting flush door bolts, consider the door construction, thickness, size and intended application. The correct bolt length and fixing position will depend on the door and frame configuration, while the finish can be selected to complement the rest of the door hardware.

Our range includes flush bolt options suitable for different door styles and interior schemes. From contemporary finishes for modern doors to classic finishes for traditional joinery, flush bolts can provide practical functionality without distracting from the overall appearance of the door.

Discreet and Reliable Door Security

One of the key advantages of flush bolts is their discreet design. Unlike surface-mounted bolts, they can be recessed into the door, helping maintain clean lines and a professional finish. This makes them particularly suitable for high-quality joinery, bespoke doors and architectural projects where attention to detail is important.

Whether you need flush bolts for French doors, double door flush bolts, internal door bolts or replacement architectural ironmongery, our collection offers practical solutions for securing door leaves while maintaining a clean and coordinated appearance.
