FH-023 Hex Bolt Nut Washer Self-Tapping Screw Assortment Kit

Product Details

This comprehensive mixed fastener kit integrates multiple commonly used hardware parts to meet one-stop fixing demands for construction equipment assembly, industrial machinery maintenance and daily DIY renovation. Two carbon steel strength grades are optional: cost-effective Grade 4.8 for light load household fixing, and high tensile Grade 8.8 for heavy structural and mechanical equipment connection.

Complete size coverage from M3 to M12 covers all mainstream small and medium fixing specifications, with three anti-rust surface treatments including zinc white, yellow zinc and matte black oxide. Each set is pre-matched with hex bolt, hex nut, flat washer, spring washer and self-tapping screw, eliminating separate procurement of scattered accessories for installers. The compartment plastic storage box design sorts each specification independently for easy storage and quick picking during construction.

Multiple packaging modes are supported for retail and wholesale demand, from small compartment retail boxes to large export cartons and bulk polybags. We provide full OEM & ODM customization service including private logo printed storage boxes, bespoke mixed size matching schemes, custom steel grades and exclusive anti-rust surface finishes, serving global construction hardware wholesalers and offline DIY tool retailers.
