About Khang Dat Construction And Investment JSC - Fasteners and Steel Wire Supplier in Viet Nam

Khang Dat Construction And Investment JSC is a Viet Nam-based supplier listing 11 active products across five top categories: Screws, Steel Wires, Nuts, Door Closer/Opener, and Fasteners. The catalogue centres on carbon steel fasteners and low-carbon steel wire, with specific entries covering white plated DIN 7504K corrugated screws, oil-yellow sharp-pointed wood screws, galvanized machine screws, gold-plated corrugated iron screws, and 17-point split-head wood screws. Steel wire products are listed under HS code 7217.10 (steel wire SAE1006, low carbon steel with C 0.06% max and Mn 0.25-0.40%) and HS code 7217.20 (hot dipped galvanized steel wire), placing the supplier firmly within Viet Nam's carbon steel wire and fastener export segment.

The supplier also lists a carbon steel door closer/opener (HS code 8302.41) and a 7-color plated carbon steel fastener (HS code 7318.15), indicating activity across both construction hardware and general-purpose fastening items. Viet Nam's northern industrial provinces, particularly around Hanoi and Hai Phong, host a significant share of the country's carbon steel fastener and wire manufacturing base, supplying both domestic construction demand and export markets. The combination of low-carbon wire rod grades (SAE1006) and zinc-coated wire alongside plated wood and corrugated screws reflects the standard product mix that Vietnamese fastener exporters typically offer to construction, furniture, and OEM buyers.

Product Range and Specialties of Khang Dat Construction And Investment JSC

The catalogue at Khang Dat Construction And Investment JSC spans roughly four product families: self-drilling and wood screws, low-carbon steel wire (both bright and galvanized), machine screws, and a small selection of builders' hardware. The screws range covers DIN 7504K corrugated self-drilling screws in white plating, oil-yellow zinc plated wood screws, hot-dip galvanized machine screws, and gold-plated corrugated iron screws, with thread sizes referenced as M4 to M24 on the carbon steel ECU galvanized entry. The wood-implanted iron oyster (HS code 7318.15) is a plated carbon steel fastener with 7-color plating, while the door opener/closer (HS code 8302.41) is a carbon steel builders' hardware item.

Buyers of these categories typically work with established fastener grades and specifications. Wood screws are commonly supplied to DIN 97 (slotted countersunk), DIN 7996 (cross recessed countersunk), or ASME B18.6.1 standards, with sizes from roughly 2.5 mm to 10 mm diameter and lengths from 10 mm to 200 mm. Self-drilling screws to DIN 7504K are usually produced in steel grades C1022 or C1018 with case-hardened surfaces, with hex washer head or bugle head profiles and drill-point sizes from #2 to #5. Low-carbon steel wire grades such as SAE1006 (C 0.06% max, Mn 0.25-0.40%) and SAE1008 are standard for nail, mesh, and binding wire production, with typical diameters from 0.5 mm to 8 mm and tensile strength in the 300-500 MPa range depending on drawing. Hot-dip galvanized wire under HS 7217.20 is normally supplied to ASTM A641 Class 1 or Class 3 with zinc coating weights of 30-300 g/m², while electro-galvanized wire typically meets ASTM A641 with thinner 3-25 g/m² coatings.

Sourcing from Khang Dat Construction And Investment JSC - Buyer Guidance

Buyers sourcing from Khang Dat Construction And Investment JSC should request a current catalogue with exact product dimensions, thread pitch, head type, drive type, and plating thickness, as fastener specifications vary widely even within a single category. For steel wire, confirm the wire grade (SAE1006, SAE1008, or other), diameter tolerance (commonly ISO 6989 or ASTM B6), tensile strength range, elongation percentage, and zinc coating weight in g/m² for galvanized products. Mill Test Certificates (MTC) to EN 10204 3.1 should be requested for each shipment, along with a pre-shipment inspection report from a third-party agency such as SGS, Bureau Veritas, or Intertek. For the door closer/opener item under HS 8302.41, confirm the fire-rating classification, EN 1154 or equivalent compliance, and cycle testing results if intended for commercial building use.

Before placing a full order, it is advisable to request physical samples of each screw type and wire coil, verify plating adhesion through cross-hatch or bend testing, and check thread gauge compliance with the relevant DIN or ISO standard. Confirm the supplier's manufacturing or sourcing capacity, lead time per SKU, and minimum order quantities (MOQs), which for fasteners typically range from 1 to 5 tonnes per item and for wire from 5 to 25 tonnes per diameter. Clarify packaging specifications, palletization, container loading plans, and whether the supplier can arrange third-party pre-shipment inspection at the loading port. Finally, confirm which certifications the supplier currently holds versus which ones the buyer must source independently, as standards documentation is the single most important verification step in this product category.
