Flush Bolts

Flush bolts are fitted into the edge of a door so the bolt sits neatly flush with the door face. They are commonly used to secure the inactive leaf of double and French doors, allowing the active leaf to open and close normally.

Browse lever-action and slide flush bolts in a range of sizes and finishes. For an alternative surface-mounted solution, see our surface bolts or explore the complete door bolts range.

Flush Bolt Buying Guide

What is a flush bolt used for?

A mortice flush bolt is recessed into the edge of a door and shoots a bolt into the frame head or floor. It is commonly used on the inactive leaf of a pair of double doors, keeping it securely in place while the active leaf operates normally.

What is the difference between lever-action and slide flush bolts?

Lever-action flush bolts are operated using a small lever, making them convenient where the inactive door leaf is opened regularly. Slide-action flush bolts use a recessed slide and provide a simple, discreet method of securing the door.

Do I need a dust socket?

A dust socket provides a clean, protected recess for the bolt when it enters the floor or frame. It helps prevent dirt and debris from collecting in the bolt hole and should be selected to suit the installation surface.

Which finish should I choose?

For frequently used or exposed applications, stainless steel and solid brass offer durable options. Plated finishes can be chosen to coordinate with your existing door handles, locks and other door furniture.
