Q
What makes fish scale expansion bolts suitable for hollow bricks?
The unique fish scale anti-slip texture on the sleeve increases friction and provides a better grip on the internal structure of hollow or porous materials, preventing the bolt from slipping or rotating during installation.
Q
Are these bolts corrosion-resistant?
Yes, they undergo a surface galvanization process which provides a protective layer against rust and corrosion, making them suitable for humid indoor settings and standard outdoor environments.
Q
Can I use these for heavy mechanical equipment?
Absolutely. These bolts are made from high-grade quenched carbon steel, offering high tensile strength and load-bearing capacity, specifically designed to provide stable support for mechanical accessories.
Q
Do you offer different sizes for different wall thicknesses?
Yes, we provide a complete range of specifications with varying diameters and lengths. We also support customized processing to meet specific project requirements.
Q
Is special equipment needed for installation?
No special tools are required. They feature a standard hexagonal head design that is compatible with common wrenches and standard installation tools found on most construction sites.
Q
Do these products meet international quality standards?
Yes, our fish scale expansion bolts comply with international building fastener standards and have passed rigorous tensile and load-bearing tests to ensure safety and quality.
