.375-16 UNC-2B Dimensions: A Comprehensive Guide
The .375-16 UNC-2B thread is a type of screw thread commonly used in various industries, including construction, automotive, and manufacturing. In this article, we will delve into the dimensions of the .375-16 UNC-2B thread, its applications, and the importance of understanding its specifications.
What is .375-16 UNC-2B?
The .375-16 UNC-2B thread is a type of Unified National Coarse (UNC) thread, which is a standard thread form used in the United States and Canada. The "UNC" designation indicates that the thread is a coarse thread, which means it has a larger pitch (distance between threads) than a fine thread.
The ".375" in the designation refers to the major diameter of the thread, which is 0.375 inches (9.52 mm). The "16" refers to the threads per inch (TPI), which means there are 16 threads in one linear inch.
The "2B" designation refers to the thread class, which indicates the tolerance and fit of the thread. In this case, the "2B" class is a medium-fit thread, which means it has a moderate tolerance and is suitable for general-purpose applications.

- Minimum thread length: 1.25 inches (31.75 mm)
Applications of .375-16 UNC-2B Thread
The .375-16 UNC-2B thread is commonly used in various applications, including:
- Automotive: engine mounts, transmission mounts, and suspension components
- Construction: anchors, bolts, and nuts for building structures
- Manufacturing: machinery, equipment, and assembly components
Importance of Understanding .375-16 UNC-2B Dimensions
Understanding the dimensions of the .375-16 UNC-2B thread is crucial in ensuring proper fit, function, and safety in various applications. Incorrect thread dimensions can lead to:
- Thread stripping: when the threads are damaged or stripped, causing the fastener to fail
- Over-tightening: when the fastener is over-tightened, causing damage to the surrounding material
- Loose fit: when the threads do not fit properly, causing the fastener to come loose over time
In conclusion, the .375-16 UNC-2B thread is a widely used thread form with specific dimensions that must be understood and followed to ensure proper function and safety in various applications.
