As highlighted in the National Institute of Standards and Technology (NIST) guidelines, fasteners play a critical role in ensuring structural safety and performance. The A193-B7/A194-2H bolts are designed to align with these standards, offering reliability and precision in critical applications.

Product Overview and Key Features

The A193-B7/A194-2H black stud bolts are characterized by their full-threaded design, which allows them to be used in applications requiring continuous threading from one end to the other. This design eliminates the need for separate nuts and bolts, streamlining assembly processes and reducing installation time. The bolts are available in multiple materials, including stainless steel, alloy steel, and carbon steel, ensuring versatility for different environmental and mechanical demands.

One of the standout features of these bolts is their black oxide finish, which provides mild corrosion resistance in dry environments. For enhanced protection in wet or chemically aggressive conditions, zinc-plated and ultra-corrosion-resistant coated variants are also available. These finishes not only prolong the lifespan of the bolts but also maintain their structural integrity under challenging conditions.

Another key advantage is the high tensile strength of the A193-B7/A194-2H bolts. They are manufactured to meet industry standards such as A193-B7 (for high-temperature applications) and A194-2H (for nuts used with high-strength bolts). This ensures that the bolts can withstand heavy loads and extreme temperatures, making them ideal for critical structural connections.

Technical Specifications and Thread Variants

The A193-B7/A194-2H black stud bolts are available in a wide range of thread specifications, catering to diverse engineering requirements. The following table provides an overview of the standard thread sizes and their corresponding pitch (P) and weight per thousand pieces:

Thread Size (d) Coarse Thread (P) Closely-Pitched (P) Weight (kg, 1000 pieces)
M2 0.4 / 18.7
M2.5 0.45 / 30
M3 0.5 / 44
M4 0.7 / 78
M5 0.8 / 124
M6 1.0 / 177
M8 1.25 1.0 319
M10 1.5 1.25 500
M12 1.75 1.5 725
M16 2.0 1.5 1330
M20 2.5 1.5 2080
M24 3.0 2.0 3000
M30 3.5 2.0 4750
M36 4.0 3.0 6900
M42 4.5 3.0 9400
M48 5.0 3.0 12400

The coarse thread variants are ideal for general-purpose applications, while the closely-pitched threads offer enhanced resistance to vibration and loosening. This flexibility ensures that the A193-B7/A194-2H bolts can be tailored to specific project requirements.
