Our advantage of custom bolts
One of our specialties is to make custom long bolts in carbon and stainless steels.
We welcome inquiries from stainless bolt industries about hard-to-find bolts & fasteners.
About us
Founded in 1987, Z-SINPRO started with machining bicycle screws. Then, we focused on the production of stainless wedge anchors. Throughout the years, we have helped our customers innovate patented wedge anchors and tapped into the foreign markets and stainless bolt industries.
In 2015, we set up a sourcing department to help our customers develop Custom Fasteners, like special long bolts, long stainless bolts, stainless nuts, long stainless screws, cold forge bushing, timber fastener and stainless stamping parts.
