Product Q&A

Q:What material is the back bolt made of?

It is manufactured from high-quality 304 stainless steel. We also offer 316 stainless steel for coastal and highly corrosive environments upon request.

Q:What applications is this back bolt suitable for?

It is widely used for fixing marble, granite, ceramic panels, porcelain slabs, artificial stone, and curtain wall cladding systems.

Q:How does the knock-in back bolt work?

The bolt expands inside a specially drilled undercut hole, creating a secure mechanical connection without damaging the visible surface of the stone.

Q:Can you provide OEM and ODM services?

Yes. We can manufacture according to your drawings, samples, or technical specifications, including customized dimensions, materials, and packaging.

Q:Is this product suitable for outdoor use?
