Invisible
Strength

As a foundational component of the Luoqi Door Systems architectural series, the flush bolt utilizes a precision-lever action with a smooth-glide internal track. This mechanical design reduces friction during actuation, allowing for effortless deployment in high-frequency commercial settings such as conference halls, hotel ballrooms, and luxury retail galleries.

Unlike standard surface-mounted bolts, this Premium Grade set is fully recessed into the door stile, making it virtually invisible when the door is closed. This integration supports the minimalist ethos of modern Building Hardware, while the 20mm bolt throw ensures deep engagement into the dust-proof strike for maximum security.

◈ CNC Precise Milling

Every Premium Stainless Steel Flush Bolt is carved using advanced CNC milling centers. This ensures tolerances within 0.05mm, providing a tactile "click" engagement that signifies true mechanical luxury and Durable Door System longevity.

◈ Corrosion Shielding

The austenitic SS304 material inherently resists oxidation. For coastal architectural projects, an optional PVD coating is available to prevent tea-staining and maintain the architectural finish under extreme salinity, fulfilling the highest Window Hardware standards.

◈ Smooth Lever Kinematics

Our proprietary lever linkage system provides high mechanical advantage. This means less effort is required to throw the bolt, making it an ideal choice for universal design and Secure Access Control where ease of operation is a priority for end-users.

◈ Security Structural Axis

The 12mm thick solid steel rod acts as a structural reinforcement for the door leaf. In the event of an attempted breach, the load is distributed through the heavy-duty housing into the door core, significantly exceeding the performance of stamped-metal alternatives.
