Bamboo screws, named for their segmented “bamboo-like” shape, are commonly used in the internal assembly of door lock systems, particularly in residential and commercial handle sets. These screws are typically manufactured in M4 to M6 diameters, with lengths ranging from 20mm to 60mm, and are often produced using Grade 4.8 or 8.8 carbon steel depending on the load requirement. Standard surface treatments include nickel plating and black oxide, offering corrosion resistance and improved durability in indoor environments.
Unlike traditional fasteners, bamboo screws are designed to break off cleanly at a designated torque point after installation. This breakaway feature prevents tampering and ensures a flush finish—essential for security hardware. The segmented body not only contributes to anti-loosening performance but also provides a stronger grip in zinc alloy or aluminum die-cast lock bodies.
Conforming to DIN and GB standards, bamboo screws are precision-machined with tight tolerances for consistent break points and axial strength. These characteristics make them ideal for OEM and aftermarket lock manufacturers seeking reliability and theft resistance.
In modern hardware systems, the bamboo screw is no longer just a functional component—it plays a role in enhancing assembly efficiency, reducing manual labor during installation, and minimizing error rates. With the rising demand for smart and high-end door systems, the use of custom bamboo-shaped screws continues to grow across international markets.
