Threaded Stud B7 Plain With 2 A194 Grade 2H Hex Nuts

Overview

• The Threaded Stud B7 Plain with 2 A194 Grade 2H Hex Nuts by BoltCraft is engineered for environments where durability and reliability are paramount. The B7 stud material and grade 2H nuts offer a robust combination for high-pressure and high-temperature applications, ensuring a secure and lasting bolted joint. The plain finish improves torque accuracy, while the width across flats of the heavy hex nuts allows for easier handling during assembly.

Applications & Advantages

• Specifically designed for use in flanged connections, pressure vessels, structural connections, valves, and other critical applications where joint integrity is crucial under extreme temperatures and pressures. These fasteners are commonly used in structural applications and are ideal for conditions that involve vibration or thermal cycling.
• The B7 stud provides high tensile strength and excellent toughness, making it suitable for demanding industrial applications. Its alloy steel construction supports compatibility with a wide range of steel components and enhances long-term durability.
• Accompanied by two A194 2H heavy hex nuts, this assembly ensures a secure fit and enhanced load distribution. These nuts, made from medium carbon steel or alloy steel, undergo a heat treatment process including quenching and tempering to meet ASTM A194 grade 2H specification for strength and hardness.

Material & Specifications

• The stud is made from B7 high-strength alloy steel, known for its ability to withstand high temperatures and pressures without compromising performance. 
• The A194 grade 2H heavy hex nuts are crafted from carbon steel or alloy steel, quenched and tempered to meet hardness and proof load requirements. These steel nuts are designed in accordance with ASTM A194 standards, covering carbon and alloy steel nuts intended for use in high temperature and high pressure environments. Both the stud and nuts conform to size, dimension, and thread standards, ensuring compatibility with industry-standard fasteners.

Reliability & Performance

• Designed to maintain integrity in extreme conditions, the combination of B7 stud and A194 grade 2H nuts offers a secure fastening solution that resists loosening under vibration and thermal cycling. The heavy hex nut design provides a wider bearing surface, improving clamp load distribution and performance under structural stress.
• The plain finish on the stud allows for accurate torque application, and the assembly supports maximum durability through proper material selection and heat treatment. These components are intended for use in environments that demand both high strength and stability, including pressures and temperatures beyond standard service conditions.

Testing & Compliance

• Each component in the assembly undergoes rigorous testing for mechanical properties, including tensile strength, proof load, yield strength, elongation, and hardness. These fasteners meet ASTM A193 and ASTM A194 specifications, ensuring compliance with industry standards for chemical composition, physical properties, and heat treatment requirements.
• Compliant with the latest ASTM standards, this B7 stud and grade 2H nut assembly provides peace of mind in its performance and reliability across a wide range of structural and mechanical applications.
