Frequently Asked Questions (FAQ)
What substrates are fish scale expansion bolts best suited for?
They are specifically engineered for lightweight and porous materials such as hollow bricks, porous blocks, aerated concrete, and other thin-walled substrates where traditional expansion anchors tend to slip.
How does the fish scale pattern improve anchoring performance?
The specialized fish scale pattern on the expansion sleeve significantly maximizes surface friction against the borehole walls, preventing backward slipping and distributing mechanical stress evenly across the substrate.
Can these expansion bolts be used for outdoor installations?
Yes, the surface receives a protective galvanized anti-rust treatment that offers reliable corrosion resistance in both humid interior spaces and typical outdoor environments.
What tools are required to install this fastener?
The bolt features a standard hexagonal head compatible with common wrenches. It fits standard threaded rods and standard installation tools without requiring specialized machinery.
Are custom sizes and lengths available for large-scale projects?
Yes, we provide full standard product specifications across various diameters and lengths, and custom processing is supported to match your specific engineering load and wall thickness demands.
Do these bolts meet structural safety and industry standards?
Yes, they comply fully with international building fastener standards and pass rigorous tensile and load-bearing tests to ensure vibration resistance and long-term joint integrity.
