Fastener Product Categories

China-sourced standard fasteners — including bolts, studs, threaded rods, nuts, washers, screws, and anchors — are widely procured for construction, infrastructure, machinery, energy, and industrial assembly applications worldwide. Common requirements typically reference DIN, ISO, or ASTM standards, with property classes such as 4.8, 8.8, 10.9, and 12.9 for bolts and matching nut classes of 8, 10, or 12. Materials include carbon steel, alloy steel, and stainless steel grades 304 and 316, with surface finishes such as zinc plating, hot-dip galvanizing, black oxide, zinc flake coating, and mechanical plating depending on corrosion and environmental exposure requirements. Before sending an RFQ, buyers should prepare product type, standard reference, dimensions, grade or class, material, surface finish, quantity, packing method, and required inspection documents. We support sourcing communication for standard fasteners, mixed SKU orders and 20ft container planning, DIN / ISO / ASTM fastener requirement review, zinc plated, hot-dip galvanized, black oxide, zinc flake and stainless steel finish options, trial and bulk order RFQ review, and Hebei / Yongnian fastener cluster sourcing where applicable. Prices, MOQ, delivery lead time, packing details, and documentation requirements are confirmed after manual RFQ review. Product images are representative only; final specifications should be confirmed by buyer drawings, standards, samples, or purchase lists.
