Sinsun Hardware expands global wholesale self drilling screw export reach

Sinsun Hardware says it is supplying self drilling screws to buyers in more than 90 countries from its Tianjin base, backed by a 30,000-square-meter facility, in-house testing, and annual output above 8,500 containers. The company is positioning its integrated manufacturing and export setup for importers that need consistent specifications, broad SKU coverage, and large-volume delivery.

Why it matters: - Self drilling screws are a high-volume fastener category used in steel framing, roofing, structural work, and trailer assembly. - Importers need suppliers that can hold specifications steady across multiple SKUs and large container shipments. - Sinsun Hardware is pitching an integrated production-and-export model for buyers that want one source for manufacturing, warehousing, inspection, and shipping.

What happened: - Sinsun Hardware, the brand of Tianjin Sinsun Imp And Exp Co., Ltd., says it has operated since 2006 in Tianjin, China. - The company says it exports to more than 90 countries and serves ten primary markets: Saudi Arabia, the UAE, Russia, Mexico, Canada, India, Vietnam, Brazil, Indonesia, and Thailand. - Annual revenues exceed $20 million, and annual supply is above 8,500 containers. - The company directs importers to its website for project requirements: official website.

The details: - Sinsun Hardware says its self drilling screw line includes TEK screws, roofing screws, wood screws, concrete self drilling screws, stainless steel self drilling screws, drywall self drilling screws, heavy duty self drilling screws, and hexagon head self drilling screws. - The product system covers six application substrates: aluminum, wood, steel, roofing, plastic, and trailer decking. - The broader portfolio spans more than 20,000 fastener SKUs, including self drilling, self tapping, drywall, roofing, and concrete screws, plus nails, rivets, anchors, bolts, nuts, and washers. - The production system uses C1022A steel sourced from Ansteel Group. - The company says its quality process includes more than 12 steps, covering surface finish, dimensions, tensile performance, hardness, torque, and corrosion resistance. - Ruspert-coated self drilling screws are listed at 1,000+ hours of salt spray resistance. - The official self drilling screw page lists a minimum order quantity of 5,000 pieces. - Listed lead times are 5-10 days for in-stock items and 20-25 days for out-of-stock items, depending on final specification, quantity, packaging, and order confirmation. - Custom head types, coatings, thread forms, lengths, diameters, and packaging are available. - The company says its factory covers 30,000 square meters and runs more than 200 German-imported multi-station cold heading machines. - Four in-house heat treatment lines have a combined 20-ton daily capacity. - A dedicated 12,000-square-meter warehouse includes more than 18,000 pallet positions. - The service flow runs through consultation, design and quotation, sample approval, production QC, final inspection, and packing and shipping. - Material traceability documents, including mill test certificates where applicable, can be provided. - Third-party inspection can be arranged through SGS, BV, or another buyer-nominated agency.

Between the lines: - The company is not just selling a product line. It is selling supply-chain simplicity for buyers managing multiple fastener specifications across regions. - The combination of in-house heat treatment, warehouse capacity, and inspection documentation is aimed at reducing variability between samples and finished production lots. - The geographic spread suggests demand is coming from both roofing-heavy and structural-steel markets, which favors suppliers with broad SKU coverage.

What's next: - Buyers can submit substrate, material thickness, head type, coating, length, and expected volume for specification review, samples, and pricing. - The company says technical support is available for specification comparison across self drilling and self tapping screws. - Order terms, model availability, and inspection scope are confirmed during quotation.

The bottom line: - Sinsun Hardware is positioning itself as a large-scale, specification-driven exporter for self drilling screws, with the manufacturing depth to support repeat container-level orders across multiple markets.
