Superior Corrosion Resistance

Engineered from silicon bronze alloy (CuSi3), these hex bolts provide outstanding resistance to corrosion, especially in damp, high-humidity, and saltwater environments. This characteristic makes them a preferred choice for marine and chemical processing applications where longevity and durability are critical.


Versatile Threading and Sizing Options

Available in metric, UNC, and UNF thread types, as well as full or partial threading, these bolts cater to a variety of assembly needs. With diameters from M5 to M24 and lengths up to 200mm, users can choose the perfect fit for diverse industrial, electrical, or construction projects.


Manufactured to International Standards

Each bolt is produced following DIN 933, ISO 4017, and ASTM B927 standards, ensuring consistent quality and reliable performance. Manufacturing tolerances and lead times (24 weeks) align with global expectations for precision fasteners.

FAQs of Silicon Bronze Hex Bolts:


Q: How do silicon bronze hex bolts perform in marine or saltwater conditions?

A: Silicon bronze hex bolts offer excellent corrosion resistance in marine and saltwater environments due to their copper-silicon composition, making them highly durable and ideal for docks, shipbuilding, and other maritime uses.

Q: What thread types and finishes are available for these bolts?

A: They are offered with metric, UNC, or UNF threads, and finishes include plain, polished, and passivated options to suit varying application preferences and exposure requirements.

Q: When should I choose silicon bronze bolts over other fasteners?

A: These bolts are recommended when exposure to moisture, chemicals, or high humidity is expected, as their alloy composition resists rust and degradation far better than standard steel or stainless alternatives.

Q: Where are silicon bronze hex bolts typically used?

A: Common applications include marine constructions, electrical installations, chemical processing plants, and industrial machinery where consistent high performance in harsh environments is necessary.

Q: What is the manufacturing process for these hex bolts?

A: Silicon bronze hex bolts are either forged or machined, then annealed to provide the desired combination of strength and ductility, meeting international tolerances and standards.

Q: How are these bolts packaged and delivered?

A: They can be supplied in bulk, boxes, or polybags depending on order requirements. Typical lead time is between 2 to 4 weeks after confirmation, accommodating both large- and small-scale projects.

Q: What benefits do silicon bronze bolts offer in demanding environments?

A: Benefits include high tensile strength (370655 MPa), broad temperature tolerance (-100C to +300C), and minimal maintenance needs due to their natural resistance to corrosion and wear.
