The name TIANZHUOJINSHU is a romanised commercial rendering of the Chinese name 天卓五金.

• 天卓 (Tianzhuo) — the brand name.
• 五金 (wǔjīn) — literally “five metals”, but in modern Chinese commercial usage refers broadly to hardware, metal fittings, tools and fastening products.

Accordingly, Tianzhuo Hardware is a more natural English interpretation of 天卓五金 than a literal translation of the individual Chinese characters. It is important to distinguish TIANZHUOJINSHU from other businesses using the word “Tianzhuo” (天卓). Available marketplace evidence specifically identifies the products sold under the TIANZHUOJINSHU name with Tianzhuo Hardware, while corporate and patent records identify Zhongshan Tianzhuo Hardware Technology Co., Ltd. as a related hardware enterprise 1.

The company most strongly associated with the brand is Zhongshan Tianzhuo Hardware Technology Co., Ltd. Public business information lists the company as a Chinese metal products and hardware enterprise located in the Zhongshan Torch Development Zone, Guangdong Province. A current business listing gives a registered capital of RMB 6.06 million, a legal representative of Feng Weijian (冯伟坚), and a business scope covering hardware product research and development, hardware manufacturing and wholesale, metal material manufacturing, construction materials, doors and windows, metal tools, metal daily-use products, furniture and related manufacturing and services.

Chinese government records also list Zhongshan Tianzhuo Hardware Technology Co., Ltd. among science-and-technology-based small and medium-sized enterprises, and the company appears in Guangdong’s 2019 high-tech enterprise list.

There is some inconsistency in publicly available company profiles concerning the company’s founding year. One business profile states that the company was established in 2002, whereas current corporate registration information gives 10 March 2016 as the establishment date. The latter appears to refer specifically to the currently registered legal entity, so the two dates should not automatically be treated as contradictory; the earlier date may relate to the business’s historical operations or predecessor organisation.

The publicly visible product range of TIANZHUOJINSHU is centred on mechanical fastening and general hardware.

Screws

The brand offers a broad range of machine and fastening screws, including:

• Hex socket screws
• Countersunk screws
• Flat head screws
• Socket head screws
• Set screws and grub screws
• Self-tapping screws
• Security and tamper-resistant screws
• Phillips head screws
• Flanged screws
• Shoulder and specialty screws

Marketplace listings show products manufactured from materials such as 304 stainless steel, 316 stainless steel, carbon steel, alloy steel and other commonly used fastening materials 1.

Bolts, nuts and washers

Listings for 天卓五金 show numerous combinations of:

• Hex bolts
• Hex nuts
• Stainless steel nuts
• Flat washers
• Spring washers
• Bolt and nut kits
• Combination fasteners
• High-strength fasteners

The catalogue covers multiple strength grades and sizes, including 8.8, 10.9 and 12.9 grade steel fasteners as well as 304 and 316 stainless steel products.

Stainless steel hardware

Stainless steel products form a significant part of the visible TIANZHUOJINSHU catalogue. Examples include:

• 201 stainless steel eye bolts
• 304 stainless steel screws
• 304 stainless steel threaded rods
• 304/316 stainless steel bolts
• Stainless steel expansion bolts
• Stainless steel retaining components

The use of 304 and 316 stainless steel positions many of these products for applications where corrosion resistance is more important than with ordinary carbon steel fasteners 1.

Expansion and installation hardware

The brand also sells hardware intended for construction, installation and DIY applications. One example is its range of hollow-wall expansion screws, offered in sizes including M4, M5, M6, M8 and M10 and marketed for fixing materials such as gypsum board and hollow walls 1.

General mechanical hardware

Other identified products include threaded bars, retaining rings, knobs, handles and various specialised fastening components 1.

Based on the available catalogue, TIANZHUOJINSHU is best characterised as a general-purpose industrial and hardware fastening brand rather than a consumer-facing lifestyle brand. Its product strategy appears to emphasise:

1. Large SKU variety — many diameters, lengths, thread types and head styles.
2. Multiple material choices — particularly stainless steel and high-strength steel.
3. Standardised metric sizes — many products are specified using M-series dimensions such as M2, M3, M4, M5, M6, M8, M10, M12 and larger.
4. Industrial and maintenance applications — products are suitable for machinery, fabrication, construction, furniture, equipment maintenance and DIY work.
5. Online distribution — the brand is prominently visible through Chinese and Southeast Asian e-commerce marketplaces.

The company associated with Tianzhuo has a more specialised background in lock hardware than the current TIANZHUOJINSHU marketplace catalogue alone might suggest. Patent records identify Zhongshan Tianzhuo Hardware Technology Co., Ltd. as the assignee of multiple inventions and utility models concerning locks and lock cylinders. For example, the company was the assignee of a 2018 patent for a lock cylinder and a 2021 utility model concerning a connectable lock cylinder.

Another patent record shows that a lock cylinder patent originally associated with inventor Feng Weijian was transferred to Zhongshan Tianzhuo Hardware Technology Co., Ltd. in 2017, providing evidence of the company’s involvement in lock cylinder technology. More recently, a 2025 patent application attributed to the company concerned a clutch mechanism and electronic lock, indicating continued development in locking and electromechanical hardware. This suggests that the company’s technical background encompasses both precision lock hardware and the broader fastening and metal hardware market.

TIANZHUOJINSHU products can be broadly divided according to application:

The exact suitability of an individual product depends on its material, strength grade, dimensions, surface treatment and application requirements.

TIANZHUOJINSHU has a visible presence in cross-border e-commerce, particularly on Southeast Asian marketplaces. For example, Lazada Singapore listings identify products explicitly as “TIANZHUOJINSHU” and associate them with a Tianzhuo Hardware Flagship Store. Products listed there include stainless steel screws, security screws, threaded rods, expansion screws and other mechanical hardware 1.

The brand is also visible on Philippine and Malaysian marketplace listings, indicating distribution beyond mainland China. Chinese e-commerce evidence is considerably broader: JD.com search results show 天卓五金 products across thousands of listings, including stainless steel nails, expansion bolts, screws, washers, high-strength socket screws and other industrial fasteners.

Available product descriptions frequently specify material grades and mechanical grades rather than presenting the brand primarily through consumer-oriented marketing claims. Examples include:

• 304 stainless steel
• 316/316L stainless steel
• 201 stainless steel
• 8.8 grade steel
• 10.9 grade steel
• 12.9 grade steel

These specifications are important because fastener performance depends heavily on material, strength class, thread dimensions and manufacturing tolerances. Listings should therefore be evaluated on the specifications of the individual product rather than assuming that every TIANZHUOJINSHU product has identical performance characteristics.

One notable characteristic of the company behind Tianzhuo is its patent activity. Documented patents include technologies involving:

• Lock cylinders
• Lock cylinder and key matching systems
• Connectable lock cylinders
• Electronic lock mechanisms
• Clutch mechanisms for electronic locks

For example, CN213539993U, published in 2021, describes a connectable lock cylinder assigned to Zhongshan Tianzhuo Hardware Technology Co., Ltd. The company was also included in Guangdong’s 2019 list of high-tech enterprises, with certificate number GR201944008953.

TIANZHUOJINSHU appears to occupy a value-oriented industrial hardware position, with a particularly broad assortment of standardised fasteners rather than a narrow premium specialty product line. Its strongest visible characteristics are:

• Broad selection of fastener types
• Extensive size availability
• Stainless steel options
• High-strength fasteners
• Assorted hardware kits
• Industrial and DIY applicability
• Chinese domestic and Southeast Asian online distribution

Because much of the brand’s international presence is marketplace-based, consumers may encounter the name primarily on individual product pages rather than through a large standalone corporate website.

The evidence supports the following working identification:

TIANZHUOJINSHU → 天卓五金 → Tianzhuo Hardware → associated with Zhongshan Tianzhuo Hardware Technology Co., Ltd.

The exact English capitalisation “TIANZHUOJINSHU” appears to function primarily as an e-commerce and marketplace brand rendering. Meanwhile, Chinese domestic listings use 天卓五金 as the brand name. It is therefore advisable to avoid claiming that “TIANZHUOJINSHU” is the company’s official registered English corporate name unless additional trademark or corporate registration documentation confirms this.

Available marketplace evidence shows generally positive individual reviews on several TIANZHUOJINSHU products. For example, some Lazada listings display 5.0/5 ratings, with customers commenting positively on product quality, fit and shipping 1. However, these are small samples and should not be interpreted as an independent assessment of the brand’s overall quality.

Likewise, Chinese JD listings show substantial review activity for some 天卓五金 products, including certain fasteners with dozens or hundreds of reviews.

In summary, TIANZHUOJINSHU is best understood as the international marketplace-facing name for Tianzhuo Hardware (天卓五金), a Chinese hardware brand associated with a Zhongshan-based metal products company. Its visible commercial range is dominated by screws, bolts, nuts, washers, threaded rods, expansion hardware and other fastening components, with a strong emphasis on stainless steel and standardised metric products. At the corporate and technical level, the associated Zhongshan company also has a history of lock cylinder and electronic lock research and development, including multiple patents and recognition as a high-tech enterprise.

The main limitation when researching the brand is that public English-language information is sparse. Consequently, details such as a definitive founding history of the brand itself, official English corporate name, global revenue, international market share, manufacturing facility count and official brand history cannot currently be established with the same confidence as the product and corporate information above.

Basic information

If encountered on a screw, bolt, nut or other metal fastening product, TIANZHUOJINSHU most likely refers to 天卓五金 / Tianzhuo Hardware rather than a fashion, electronics or consumer goods brand. The brand’s core identity is Chinese industrial hardware and fastening products, while its associated company has a deeper technical history in lock and security hardware 1.
