Stainless Steel Hexagon Flange Bolts
Product Overview
Stainless steel hexagon flange bolts are a type of fastener characterized by their six-sided head and integrated washer-like flange. Designed to distribute the load and resist loosening, these bolts are extensively used for their superior grip and corrosion resistance. Precision-engineered and crafted from durable stainless steel, stainless steel hexagon flange bolts are ideal for high-stress applications across industries including automotive, construction, and heavy machinery.
At FLYBEAR FASTENER, we manufacture a wide range of hex flange bolts ensuring exceptional quality, precision, and performance under demanding conditions.

Material Introduction & Manufacturing Process
At FLYBEAR FASTENER, stainless steel hexagon flange bolts are primarily manufactured using A2 (304) and A4 (316) grade stainless steel for exceptional corrosion resistance and strength.
The production workflow includes:
- Raw Material Selection (Premium stainless steel wire rod)
- Cold/Hot Forging (to form bolt head and body)
- Thread Rolling (external threading processed through dies)
- Heat Treatment (to reach required mechanical properties)
- Surface Finishing (passivation, polishing or coating)
- Quality Inspection (dimensional checks and strength tests)
- Packaging & Warehousing
This process ensures consistent quality, tight tolerances, and long-lasting performance.
Common Industries and Applications
Stainless steel hexagon flange bolts are widely used in:
- Automotive engine and chassis components
- Marine hardware and shipbuilding
- Industrial machinery and plant maintenance
- Structural steelwork and building construction
- Renewable energy installations (solar & wind)
- Chemical processing equipment
Their flange provides a built-in washer surface, significantly improving clamping efficiency and vibration resistance, making them ideal for high-load environments.
