A193 B7 Hex Bolts with A194 2H Heavy Hex Nuts Length 30 mm Bolts and Nuts,

The Bolts and Nuts product is a comprehensive fastening solution engineered to meet the highest standards of quality and performance across diverse industrial applications. Manufactured with precision, these fasteners feature a thread tolerance of 0.02, ensuring a perfect fit and reliable fastening every time. This tight tolerance minimizes play between threads, enhancing the overall strength and durability of assembled components.

Each unit comprises a complete set: one bolt, one nut, one washer, and a sealing ring. This all-inclusive approach guarantees that customers receive everything necessary for secure and effective fastening in a single package, simplifying procurement and assembly. The sealing ring plays a crucial role in preventing leaks and protecting the joint from environmental factors such as dust, moisture, and corrosive agents.

Bolts are available in a variety of head styles to suit different installation requirements and aesthetic preferences, including flat, oval, round, and hex. The hex head style is particularly popular for its ease of installation using standard wrenches and power tools, offering excellent torque transmission and grip.

Packaging is carried out with utmost care, with all bolts and nuts securely stored in sturdy wooden cases. This ensures safe transportation and storage while protecting components from damage and contamination. Wooden packaging is environmentally friendly and robust, adding an extra layer of reliability to product delivery.

A standout feature of this product line is the flexibility in the number of nuts supplied per bolt. Customers can choose between packages containing either two or three nuts per bolt, depending on their specific application needs. This adaptability caters to scenarios requiring additional fastening security or redundancy, making the product suitable for critical applications where safety and reliability are paramount.

The materials used in these bolts and nuts are selected for exceptional strength and resistance to harsh operating conditions:

• ASTM A354 Grade BD alloy steel bolts — known for high tensile strength and toughness, ideal for demanding mechanical and structural applications.
• ASTM A449 high strength carbon steel hex bolts — offering excellent mechanical properties and durability under heavy loads.
• ASTM A193 B7M bolts — comply with NACE MR0175 standards for sour gas service, withstanding corrosive effects without compromising integrity. Suitable for the oil and gas industry, chemical processing plants, and other sectors where safety under corrosive conditions is critical.
