Direct access to our engineered fasteners designed to meet the rigorous performance standards of Kansai's advanced industrial sectors.
Osaka, historically dubbed the "Manchester of the Orient," stands as the industrial heartbeat of western Japan. Within the Kansai region, Osaka has cultivated a dense, highly specialized ecosystem of small-to-medium enterprises (SMEs) alongside global manufacturing giants. The city of Higashiosaka, in particular, is world-renowned for its metalworking, precision machining, and fastener manufacturing clusters. Every component, from micro-screws utilized in high-density electronics to heavy-duty industrial bolts, is engineered with meticulous Japanese craftsmanship.
Among the critical components driving Osaka's electronics, automotive, and marine sectors are brass self-tapping screws. Brass, an alloy primarily composed of copper and zinc, is highly sought after in these localized industries due to its unique physical and chemical properties. Unlike standard carbon steel, brass offers superior resistance to atmospheric corrosion, exceptional electrical conductivity, and non-magnetic properties. These characteristics make brass self-tapping screws indispensable for electrical enclosures, precision instrumentation, and coastal marine equipment manufactured throughout Osaka's industrial zones.
In Osaka's manufacturing philosophy, a fastener is never "just a screw." It is a critical node of structural integrity and electrical grounding. Localized factories demand components that strictly adhere to JIS (Japanese Industrial Standards) and international equivalents like ISO and DIN. To support this demand, modern manufacturing facilities combine decades of cold-heading expertise with advanced automated sorting and optical inspection technologies, ensuring that every batch of self-tapping screws delivers zero-defect reliability.
COMPANY PROFILE

The company's factory area exceeds 20,000 square meters. It has branches in Dongguan, Shaoguan and Wuhan, and possesses the full-process production capacity from raw material processing to product delivery. It can support the customization of international standards and non-standard drawings. It strictly adheres to ISO9001, ISO14001 and IATF16949 systems, and achieves full-process quality control through multiple tests.
Self-tapping screws represent a major leap in assembly efficiency. Unlike traditional machine screws that require a pre-tapped hole with matching internal threads, self-tapping screws cut or form their own mating threads as they are driven into the material. When combined with the metallurgical advantages of brass, these fasteners offer unparalleled performance in specific industrial niches.
Brass naturally forms a protective oxide layer that resists corrosion in highly humid, saline, or chemically active environments. In coastal cities like Osaka, marine hardware, outdoor electrical junctions, and water filtration equipment rely heavily on brass fasteners to prevent rust-induced structural failures. While steel screws will quickly corrode and seize in damp environments, brass self-tapping screws remain structurally intact and easy to remove during maintenance cycles.
Because brass is a copper alloy, it inherits high electrical conductivity. This property is crucial for grounding assemblies in consumer electronics, industrial control panels, and automotive wiring harnesses. When a brass self-tapping screw is driven into an enclosure, it not only secures the panel but also establishes a highly conductive electrical path, eliminating the need for complex grounding wires and reducing assembly times.
Eco-Friendly & Green Manufacturing Compliance
Modern brass self-tapping screws manufactured for the Osaka market strictly comply with RoHS and REACH environmental regulations. By utilizing lead-free brass alloys, manufacturers ensure that these components can be safely integrated into consumer electronics and medical devices worldwide.
In precision instrumentation, medical imaging devices (such as MRI machines), and sensitive laboratory equipment, magnetic interference can distort readings and cause system errors. Brass is non-magnetic, making it the material of choice for assembling sensitive electronic chassis, computer housings, and sound systems where electromagnetic compatibility (EMC) is a priority.
Brass has a warm, gold-like appearance that adds an aesthetic premium to exposed hardware. This makes it highly popular in high-end consumer appliances, luxury automotive interiors, and architectural hardware. Furthermore, brass has a low coefficient of friction, which reduces the torque required to drive the self-tapping screw, preventing thread stripping in softer materials like wood, plastics, and aluminum.
Founder & "Screw Prince"
Starting with a single screw, Su Yuqiang spent thirty years transforming "Yuhuang" into a reliable brand in the field of hardware manufacturing, and himself became the recognized "Screw Prince" in the industry.
Starting from scratch, he lacked funds and equipment in the early stage of his entrepreneurship, but always engraved "customer needs" in his heart. Once an American customer requested a non-standard screw, many factories failed in their trials. Su Yuqiang didn't give up: repeatedly adjusting the molds, sending samples at his own expense, once, twice... Finally, on the fifth attempt, he successfully produced a product that met the requirements. This meticulousness and persistence earned him the trust and cooperation of customers for over twenty years.
After thirty years of deep dedication, Su Yuqiang, with the belief of "tenacity and pragmatism, service first", led Yuhuang to move forward steadily; his diligence and commitment as a public servant have become benchmarks in the industry, and "centering on customers" has become the core development philosophy engraved in the bones of Yuhuang.
Osaka’s industrial landscape is highly diversified, requiring fasteners that perform under distinct environmental and mechanical stresses. Below are the primary sectors where brass self-tapping screws play a vital role:
Osaka houses major R&D facilities and manufacturing plants for consumer electronics, home appliances, and micro-optics. In these compact assemblies, micro-sized brass self-tapping screws (often with thread diameters under M2) are used to secure plastic casings to internal structural frames. The non-magnetic property of brass prevents electromagnetic interference with high-frequency communication modules, while its self-tapping nature speeds up high-speed automated assembly lines.
The Sakai-Senboku coastal industrial zone is home to massive power generation, electrical grid components, and industrial machinery plants. In heavy electrical equipment, brass fasteners are preferred for securing terminal blocks, busbars, and switchgear panels. The natural conductivity of brass prevents localized heating at connection points, reducing the risk of electrical fires and ensuring long-term operational stability.
As the automotive industry shifts toward electric vehicles (EVs), the demand for high-conductivity components has surged. Osaka's automotive parts manufacturers use brass self-tapping screws to assemble battery management systems (BMS), sensor housings, and dashboard electronics. The vibration-resistant threads formed by self-tapping screws ensure that electrical connections remain secure even under constant road vibrations.
