Shenzhen Guwanji Hardware Technology Co., Ltd. was founded in 2014, with its initial business development centred on supplying industrial fasteners and hardware across various specifications and standards. The company has since expanded its manufacturing and logistical capabilities significantly.

According to industry exhibition profiles, GUWANJI manages approximately 60,000 fastener material numbers. It operates two three-dimensional warehouses in Huizhou and Yancheng with a combined area of roughly 12,000 square metres, as well as a fastener production facility in Huizhou spanning approximately 3,000 square metres.1 In October 2023, the company reportedly obtained ISO 9001 quality management system certification.1

GUWANJI’s core business is industrial fastening hardware. Its product catalogue encompasses a wide range of components, including:

• Bolts
• Machine screws
• Socket-head cap screws
• Hex-head bolts
• Nuts
• Washers
• Threaded rods and threaded bars
• Self-tapping screws
• U-bolts
• Pins
• Rivets
• Keys
• Shafts
• Clamps
• Copper standoffs
• Thumb screws and hand screws
• Furniture hardware
• Various manual tools

Products are manufactured using diverse materials to meet varying industrial requirements. Metal offerings include stainless steel grades 302, 304, and 316, as well as carbon steel grades 4.8, 8.8, 10.9, and 12.9.3 Retail and industrial catalogues also list GUWANJI products in nylon hardware, comprising nylon bolts, screws, nuts, washers, spacers, cable ties, and protective components.2

Standards compliance

A defining characteristic of the GUWANJI product offering is its adherence to multiple international technical standards. Company documentation lists products conforming to:

• GB: Chinese national standards
• DIN: German standards
• ASTM/ANSI: United States standards
• BS: British standards
• JIS: Japanese standards
• International standards

This multi-standard approach supports industrial customers who require precise compatibility rather than generic hardware alternatives.3

GUWANJI products are utilised across a broad spectrum of industrial applications. The company’s industry profile identifies key markets including automotive, medical equipment, home appliances, new energy, construction machinery, and electronics.1 This reflects the critical role of fasteners as essential components in machinery, structural assemblies, electronic equipment, vehicles, and manufactured goods.

Unlike trading-only brands, GUWANJI integrates manufacturing, warehousing, and distribution within its operational model. Its reported infrastructure includes a fastener production factory in Huizhou and warehousing facilities in both Huizhou and Yancheng, totalling approximately 12,000 m² of three-dimensional warehouse space and 3,000 m² of manufacturing space.1

With a catalogue of roughly 60,000 fastener material numbers, the company presents itself as an integrated fastener sourcing platform capable of supplying both commonly specified items and customised, non-standard fastening solutions.1

GUWANJI’s market positioning rests on three primary pillars:

1. Extensive product selection: Supplying a vast array of dimensions, materials, and standards.
2. Industrial quality: Focusing on standardised specifications and verified material/strength grades.
3. One-stop sourcing: Enabling industrial buyers to procure multiple types of fastening components from a single supplier.

Third-party industry descriptions characterise GUWANJI as a professional industrial-fastener company that emphasises product quality, technical knowledge, and customer support.3

The GUWANJI name is formally registered as a trademark in the United States. The application was filed on 9 November 2016 under Shenzhen Guwanji Hardware Technology Co., Ltd., and registration was granted on 27 June 2017. The US registration covers various metal hardware products, including bolts, screws, nuts, washers, rivets, pins, and related metal fasteners.4

Notably, the US trademark record states that “GUWANJI” has no meaning in a foreign language. The registered logo features stylised lettering incorporating a hexagonal shape into the design.4

GUWANJI products are distributed through industrial component channels and e-commerce platforms. In China, products are available via industrial marketplaces and retail platforms, including a flagship store on JD.com.2

There is also evidence of international commercial distribution. Trade records indicate that GUWANJI-branded stainless-steel socket-head bolts have been shipped from China to Vietnam, demonstrating cross-border supply capabilities relevant to regional industrial procurement.

GUWANJI operates primarily as a B2B industrial brand rather than a consumer lifestyle label. Its value proposition is grounded in specifications, availability, material selection, pricing, technical compatibility, and supply reliability. In practical terms, GUWANJI functions as a fastener and industrial-hardware supplier and manufacturer, with its branding appearing on mechanical fastening components such as screws, bolts, nuts, and washers.

Shenzhen Guwanji Hardware Technology Co., Ltd. has been associated with other trademarks outside the hardware sector. For instance, the company previously registered RIVER SONG in the United States for clothing, footwear, and headwear.4 However, this should not be confused with GUWANJI’s current core identity; the company’s documented business activities remain overwhelmingly centred on hardware and fasteners.13

Some information regarding GUWANJI is derived from third-party industrial directories and exhibition profiles rather than direct corporate publications. Where exact corporate figures or current operating details are concerned, these should be treated as reported data rather than independently audited facts.
