Duplex Hex Bolts
High Strength & Corrosion-Resistant Fasteners for Demanding Applications
Our Duplex Hex Bolts are premium-grade fasteners engineered to provide exceptional strength and superior corrosion resistance, making them ideal for harsh environments such as marine, chemical, and offshore industries. Manufactured using duplex stainless steel, these bolts offer an excellent balance of toughness and durability with enhanced resistance to stress corrosion cracking.
Superior Corrosion Resistance: Duplex stainless steel composition (typically grade 2205) provides high resistance to chloride-induced corrosion and pitting.
High Tensile Strength: Combines austenitic and ferritic stainless steel microstructures for excellent mechanical properties, typically meeting ASTM A490 or equivalent standards.
Precision Hex Head Design: Ensures easy wrenching and tightening with standard hex tools.
Wide Temperature Range: Suitable for use in extreme temperature conditions without compromising integrity.
Versatile Sizes: Available in various diameters and lengths to meet diverse project requirements.
