About JSSX Fastener

Jiashan Sanxin Fastener Company Limited, founded in 2008, began as a local producer of flat washers serving the Chinese market. Since 2014, we expanded our operations to become a global exporter, delivering high-quality fasteners to clients in the USA, Brazil, Spain, Greece, Czech Republic, Singapore, and South Africa.

Our company spans 3,000 square meters, with half dedicated to production and the other half to packaging and warehousing. We operate two specialized factories: one in Jiangsu for stainless steel washers (SS304, SS316), and another in Jiashan Taozhuang for flat washers, spring washers, and channel nuts.

With 40 production machines and a team of 50 skilled workers, we maintain strict quality control on every order before shipment. As a direct factory, we offer competitive pricing without compromising on quality.
