Description
The 316 Stainless Steel GB5789 Bolt Hex Flange is a premium-grade fastener engineered for outstanding strength, superior corrosion resistance, and long-term reliability in harsh environments. Designed according to the GB5789 standard, this bolt features a large integrated hexagonal flange, which enhances load distribution, improves vibration resistance, and eliminates the need for a separate washer.
Manufactured from 316 stainless steel, this hex head bolt provides exceptional resistance to chlorides, seawater, industrial chemicals, and oxidation - making it the ideal fastening solution for marine, chemical, construction, machinery, and offshore applications. Its robust material, deep threading, and secure hexagonal head ensure a dependable connection in critical structural and mechanical assemblies.
Features & Benefits
- Superior Corrosion Resistance: Made from 316 stainless steel, these bolts offer exceptional resistance to chlorides and other harsh chemicals, making them far more durable than standard stainless steel fasteners in extreme conditions.
- Integrated Flange for Stability: The integrated flange design provides a larger contact area, which distributes the clamping force more evenly. This not only prevents damage to the mating surface but also provides increased resistance to vibration, ensuring the connection remains secure.
- High Durability and Wear Resistance: The robust 316 stainless steel material guarantees high hardness, strong oxidation resistance, and excellent wear resistance, ensuring a long service life without rust or deformation.
- Efficient and Reliable: The bolt's deep threads and standard hexagonal head allow for quick, non-slip installation with standard tools, providing a powerful and uniform clamping force.

FAQ:
Q1: Why is 316 Stainless Steel preferred for this Bolt Hex Flange over 304 Stainless Steel?
A: 316 Stainless Steel contains Molybdenum, which provides significantly enhanced resistance to corrosion, particularly against chlorides (salts) and strong chemicals. This makes the Bolt Hex Flange the superior choice for marine, coastal, and chemical processing applications.
Q2: How does the integrated flange improve the connection?
A: The integrated flange acts as a permanent washer, distributing the clamping force over a larger surface area. This increases the friction, prevents damage to the mating surface, and provides increased stability and resistance to vibration.
Q3: What does the GB5789 standard relate to?
A: The GB5789 standard specifies the dimensional and performance requirements for a large hexagonal flange bolt, ensuring the fastener meets Chinese national standards for strength and reliable fastening.
Q4: Does the flange replace the need for a washer?
A: Yes. The integrated flange functions like a built-in washer, increasing stability and preventing material damage.
Q5: Can this bolt withstand heavy loads?
A:Yes. The bolt’s durable construction and precise threading enable strong, uniform clamping for structural and mechanical applications.
