Hex Flange Bolts for Automotive, Machinery, and Construction
Hex flange bolts offer strong, vibration-resistant fastening for automotive systems, heavy machinery, and structural steel assembly. Because the flange sits directly under the hex head, the bolt spreads the clamping force evenly. This design improves joint stability, increases load capacity, and eliminates the need for separate washers. As a result, many engineers select hex flange bolts for high-stress mechanical structures where reliability is critical.
Material Options and Protective Finishes
We manufacture our hex flange bolts using stainless steel, carbon steel, and alloy steel. These materials deliver high tensile strength and strong resistance to wear. Additionally, several finishes are available, including plain, zinc-plated, and black oxide coatings. These surface treatments protect the bolts from corrosion in both indoor and outdoor environments. Therefore, customers can apply them confidently across a wide range of projects.
OEM Customization for Global Production
To meet specific international standards, we offer OEM customization for diameter, length, coating, and packaging. You can select metric sizes from M5 to M20 or request special thread requirements for unique applications. We also provide printed boxes, small kit packaging, and flexible shipment plans. Because many buyers need multiple deliveries throughout the year, we support them with free warehouse storage.
