304 Stainless Steel Hex Bolts, M6 to M20, Passivated for Outdoor Use

Product Description

Our 304 stainless steel hex bolts run from M6 to M20 and are passivated for outdoor use. Importers, distributors and brand owners buy them as a corrosion-resistant fastening line for construction, garden equipment and outdoor hardware assemblies, where standard zinc-plated bolts would fail early. Hex heads take standard socket and wrench sizes, so your customers can install them with tools they already own.

Key features

• 304 stainless steel gives you corrosion resistance in rain, humidity and coastal air without a coating that chips or wears through.
• Passivated finish removes surface free iron after machining and reinforces the passive layer, which is what keeps the alloy from staining outdoors.
• Metric size range M6 to M20 covers most structural and assembly fastening, so you can stock one bolt line instead of several.
• Hex head design allows high torque with a standard wrench or socket, useful where assemblies need to be tightened or serviced on site.
• Factory-direct supply from our own automated production lines means consistent thread quality and a source you can scale with your order volume.

Specifications

Applications

These bolts suit outdoor structures, fencing and railing, garden tool assemblies, and equipment that sees moisture or weather. They also work well as a hardware accessory line for distributors serving construction and landscaping trades. The passivated surface matters most where parts sit exposed: roof fixings, garden frames and any assembly that will not be painted or covered.

Customization and ordering

The MOQ is 1,000 pieces. As a manufacturer we can discuss OEM and ODM work with you: material and size variants, head style, packaging and your own branding, all manufactured to your specifications. Samples are the practical first step before a bulk order, and we will confirm lead time with you directly. We run first-article inspections before mass production, in-process monitoring and pre-shipment inspection covering appearance and function. Our bolts carry CE marking where the application requires it. For European buyers, we ship FOB, CIF or DDP on request and can supply the documentation your market needs. Talk to us with your sizes and quantities and we will quote from the factory.
