Product Q&A

Q:What material are these square block nuts made of?

They are manufactured from high-strength carbon steel, with black oxide surface treatment. Custom materials like stainless steel can be produced upon request.

Q:What is the function of the black oxidized finish?

The black coating provides basic rust and oxidation resistance during storage and indoor use, avoids surface scratches, and delivers a uniform industrial black appearance for matching machine frames.

Q:Will the black paint/coating peel off easily?

It is not spray paint but chemical black oxide treatment bonded with steel. It wont peel under normal assembly, torque tightening and indoor working conditions.

Q:What thread sizes do you offer?

Standard metric threads: M6, M8, M10, M12; imperial UNC/UNF threads are customizable. We support full-depth internal tapping for stronger locking.

Q:Can I customize the outer dimension and thickness of the square block?

Yes. Length, width, thickness, hole position and thread depth all support OEM customization. Just provide your drawing or size requirements.
