Unlike general consumer hardware retailers, the company describes itself specifically as a provider of both standard and non-standard fasteners for industrial use.1

Shenzhen Guwanji Hardware Technology Co., Ltd. was founded in 2014, with its initial business development focused on supplying industrial fasteners and hardware across various specifications and standards.

The company has since expanded its product range and supply chain capabilities. According to an industry exhibition profile, 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 covering approximately 3,000 square metres.1

In October 2023, the company reportedly obtained ISO 9001 quality management system certification.1

GUWANJI’s core business centres on industrial fastening hardware. The product range includes:

• 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 in materials including stainless steel 302, 304, and 316, as well as carbon-steel grades such as 4.8, 8.8, 10.9, and 12.9.

Retail and industrial catalogues also list GUWANJI products in nylon hardware, comprising nylon bolts, screws, nuts, washers, spacers, cable ties, and protective components.2

A key characteristic of the GUWANJI product offering is compliance with multiple technical standards. Company descriptions list products conforming to:

• GB — Chinese national standards
• DIN — German standards
• ASTM/ANSI — U.S. standards
• BS — British standards
• JIS — Japanese standards
• International standards

This multi-standard approach makes the brand relevant to industrial customers requiring specific dimensions, materials, thread types, and strength grades rather than generic hardware.

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
• Electronics

Although fasteners are relatively small components, they are essential in machinery, structural assemblies, electronic equipment, vehicles, and manufactured goods within these sectors.1

Rather than operating solely as a trading brand, GUWANJI integrates manufacturing, warehousing, and distribution. Reported infrastructure includes:

• A fastener production factory in Huizhou
• Warehousing facilities in Huizhou and Yancheng
• Approximately 12,000 m² of combined three-dimensional warehouse space
• Approximately 3,000 m² of fastener manufacturing space
• A catalogue of roughly 60,000 fastener material numbers

Consequently, the company presents itself as an integrated fastener sourcing platform capable of supplying both commonly specified products and customised or non-standard fastening solutions.1

GUWANJI’s market positioning rests on three main pillars:

1. Large product selection — Supplying a wide variety of dimensions, materials, and standards.
2. Industrial quality — Focusing on standardised specifications and material/strength grades.
3. One-stop sourcing — Enabling industrial buyers to obtain multiple types of fastening components from a single supplier.

Third-party industry descriptions similarly 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 November 9, 2016, and registration was granted on June 27, 2017, under Shenzhen Guwanji Hardware Technology Co., Ltd. This U.S. registration covers various metal hardware products, including bolts, screws, nuts, washers, rivets, pins, and related metal fasteners.4

Notably, the U.S. 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 and e-commerce channels. They are available via Chinese industrial marketplaces and retail platforms, including a GUWANJI 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.

Unlike consumer brands built around lifestyle, fashion, or mass-market recognition, GUWANJI is primarily a B2B industrial brand. Its value proposition is based on specifications, availability, material selection, pricing, technical compatibility, and supply capability.

In practical terms, GUWANJI functions as a fastener and industrial-hardware supplier and manufacturer, with its brand appearing on mechanical fastening components such as screws, bolts, nuts, and washers.

Shenzhen Guwanji Hardware Technology Co., Ltd. has been associated with other trademarks. 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 industrial identity; the company’s documented business remains overwhelmingly centred on hardware and fasteners.1

GUWANJI is a Chinese industrial hardware and fastening brand established in 2014 and operated by Shenzhen Guwanji Hardware Technology Co., Ltd. Its principal business involves the production and supply of standard and non-standard fasteners, including screws, bolts, nuts, washers, pins, rivets, clamps, and related hardware.

The company has developed an extensive product catalogue and supply infrastructure, encompassing manufacturing and warehouse facilities. It reports serving industries such as automotive, electronics, medical equipment, construction machinery, home appliances, and new energy. Its reported ISO 9001 certification, multi-standard product offering, and large fastener inventory reinforce its positioning as an industrial one-stop fastener sourcing supplier rather than a general consumer hardware brand.1

Note: Some information available online is derived from third-party industrial directories and exhibition profiles rather than GUWANJI’s own corporate publications. Where exact corporate figures or current operating details are concerned, these should be treated as reported figures rather than independently audited facts.
