Anti-Corrosion HDG M16 Grade 8.8 Bolt For W Beam Guardrail, Spacer Bracket & Cable Barrier Assembly

Product Overview

This Grade 8.8 hot-dip galvanized M16 hex bolt is a high-tensile structural fastener specially matched for highway guardrail systems. It is manufactured from premium Q235 carbon steel via quenching and tempering treatment, reaching Grade 8.8 high strength standard with tensile strength up to 800MPa, which ensures stable connection performance under heavy load and vehicle impact without fracture or thread slipping.

All bolt bodies and threads adopt full hot-dip galvanized treatment with zinc coating thickness 60–120μm. The uniform zinc layer delivers excellent resistance to salt spray, acid and alkali vapor, keeping rust-free in long-term outdoor humid, coastal and riverside road environments, greatly reducing later maintenance cost of road safety barriers.

Standard M16 metric thread is precisely machined, perfectly matched with supporting hot-dip galvanized M16 nuts, flat washers and spring washers for smooth on-site assembly. It is widely compatible with 2-wave/3-wave guardrail plate, spacer bracket, cable barrier, U/C channel open guard post and riverside U-type safety railing.

Flexible Packing Solution

Two packing options for customer selection: plastic bag packing for lightweight bulk shipment, and sturdy carton box packing to prevent extrusion and scratch during long sea transportation, protecting complete zinc coating surface. We support customized single package weight according to project order demand.

Customization & Factory Advantage

Custom service available: bolt length, zinc coating thickness and packing mode can be adjusted as project drawings. Our factory holds ISO9001, ISO14001, ISO45001 three-system certifications, and can provide test reports for overseas bidding. Unit price and production lead time are negotiable for bulk orders with stable mass supply and fast delivery.

Application Scenarios

Expressway W-beam guardrail installation, mountain cliff cable barrier assembly, lakeside & riverside municipal safety railing, industrial ball joint handrail, steel structure platform and all outdoor traffic anti-collision barrier projects.
