Import Bolt, Nut, Wahsher, Screw — Buy in Bulk from Supplier in China

These fasteners cover bolts, nuts, washers and screws in metric thread sizes from M6 to M56, with finishes in zinc, black and plain according to the supplier's range. The source description notes compliance with DIN, ANSI, JIS and ISO standards, though buyers should verify which specific standards apply to their intended order. Materials are described as robust with high tensile strength, a typical requirement for structural and mechanical fastening.

Zinc plating provides corrosion resistance for outdoor or humid environments, while black oxide offers a decorative finish with mild lubricity and plain finish suits painted or coated assemblies where additional surface treatment follows installation. Thread forms will typically be coarse (standard metric) or fine depending on application, with property classes for bolts commonly ranging from 4.8 to 12.9 in carbon steel. Washer types likely include flat and spring (lock) variants to distribute clamping load and resist loosening under vibration.
