Customization Options:
Customize material grades (e.g., 20MnTiB for higher toughness), lengths, and coatings (dacromet or phosphating). Electro-galvanized or hot-dip galvanized coatings are optional for corrosion protection in harsh environments.
We also provide testing certificates (SGS) for quality assurance.
Designed for heavy-duty applications, our High Strength Alloy Bolts meet JIS specifications, offering exceptional tensile strength and fatigue resistance. These carbon steel hex bolts are quenched and tempered for enhanced durability, suitable for structural frameworks, bridge construction, and machinery requiring load-bearing precision.
