High-performance fasteners trusted by Korean construction contractors, shipbuilders, and machinery manufacturers. Compliant with KS, DIN, and ISO standards.
Handan Yongnian District Dongshuo Fastener Manufacturing Co., Ltd. was established in 2015. It is an enterprise specializing in the production and operation of fasteners. Our company is committed to providing high-quality fastener products and providing customers with comprehensive solutions in various industries. As a reputable fastener manufacturer, we have advanced production equipment and a professional technical team to meet our customers' needs for different types of fasteners.
As a dedicated bolt, nut, and washer supplier for South Korea, we understand the stringent requirements of the Korean industrial market. From Busan's shipyards to Seoul's high-rise construction sites, our fasteners are engineered to perform under the most demanding conditions.
We offer KS-compatible specifications, full documentation support, and flexible MOQ arrangements tailored to Korean procurement standards and business practices.
South Korea is one of Asia's most dynamic industrial economies. Its advanced manufacturing sectors create massive, consistent demand for high-precision bolts, nuts, and washers across multiple industries.
South Korea is the world's second-largest shipbuilder, with Hyundai Heavy Industries, Samsung Heavy Industries, and DSME based in Ulsan and Geoje. These yards consume millions of high-tensile bolts, marine-grade nuts, and stainless washers annually for hull assembly, engine mounting, and piping systems.
South Korea's construction output exceeds KRW 250 trillion per year. Major infrastructure projects โ including smart city developments in Sejong, GTX underground rail in Seoul, and industrial complexes in Incheon โ require large volumes of structural bolts, anchor bolts, and heavy-duty washers that meet KS B 1002 and ISO 4014 standards.
Hyundai Motor, Kia, and their extensive tier-1 and tier-2 supplier networks demand fasteners with tight tolerances, surface coatings, and traceability documentation. Our galvanized and zinc-plated bolts and nuts meet IATF 16949 requirements preferred by Korean automotive OEMs and suppliers.
Korea's semiconductor industry โ led by Samsung Electronics and SK Hynix โ requires ultra-clean, precision stainless steel fasteners for cleanroom equipment, fab tool assembly, and wafer handling systems. Micro-sized bolts and washers with controlled surface finishes are increasingly in demand.
Korea's Green New Deal targets 40 GW of offshore wind capacity by 2030. Offshore wind turbine foundations, solar panel mounting systems, and hydrogen infrastructure projects all rely on hot-dip galvanized bolts, heavy hex nuts, and large-diameter flat washers that resist corrosion in marine environments.
Korean companies like Doosan Bobcat, HD Hyundai, and LS Mtron manufacture construction machinery, agricultural equipment, and industrial robots. These products require robust fastening systems โ including combination bolt assemblies, spring washers, and self-drilling screws โ supplied with consistent quality and competitive lead times.
The Korean fastener import market is evolving rapidly. Understanding these trends helps us serve Korean buyers better with forward-looking product development and supply chain solutions.
With Korea's coastal industrial zones and expanding offshore energy projects, demand for hot-dip galvanized, geomet-coated, and mechanical zinc-plated fasteners is growing year-on-year. Our galvanized bolt and washer ranges are specifically formulated to exceed KS D 9502 salt-spray standards.
Korean engineers are increasingly specifying Grade 8.8, 10.9, and 12.9 bolts as structural designs become more compact and load demands increase. We supply full-range high-strength hex bolts and nuts with mill certificates and mechanical test reports to satisfy Korean procurement requirements.
Korean conglomerates (chaebols) and their suppliers face increasing ESG scrutiny. Our factory uses environmentally friendly surface treatment processes, RoHS-compliant materials, and reduced-emission production lines โ aligning with the sustainability commitments of Korean importers and end-users.
Korean manufacturers are adopting smart factory (์ค๋งํธํฉํ ๋ฆฌ) standards. We support digital traceability with batch coding, QR-linked test certificates, and EDI-compatible documentation โ enabling seamless integration with Korean ERP and quality management systems.
Time-saving combination fastener assemblies (bolt + spring washer + flat washer pre-assembled) are gaining traction in Korean assembly lines, reducing installation time and error rates. Our combination bolt product line is specifically designed for this application.
Korean buyers increasingly require compliance with KS (Korean Industrial Standards) in addition to ISO and DIN. We work closely with Korean trading partners to ensure our products are tested, documented, and certified to meet local regulatory and quality requirements.
