Across various industries, threaded fasteners are incorporated in many assemblies to provide additional strength and stability. Due to their employment in countless settings, there are numerous types on the market. However, this blog will only be covering one type of threaded fastener: the close tolerance bolt.
Also known as precision bolts, close tolerance bolts are specialized threaded fasteners designed to fit tightly into a threaded hole. To ensure a snug and secure fit, they are manufactured to extremely precise dimensions. In applications where the alignment and stability of components are critical, this level of precision is vital.
For operation, the primary function of a close tolerance bolt is to secure two or more components together. By placing the bolt into a threaded hole, the resulting connection prevents movement and provides structural integrity. The close fit between the bolt and the threaded hole minimizes play, reduces the risk of loosening, and enhances the overall performance of the assembly.
Different Types of Close Tolerance Bolts
Apart from the security they provide, another benefit of close tolerance bolts is that they come in various types to suit different applications. One common type is the hex bolt, which features a hexagonal head and a threaded shaft. Hex bolts are incredibly versatile, so they are widely used in a range of industries. Another type is the socket head cap screw, which has a cylindrical head and a recessed hexagonal socket. These bolts offer a low-profile design and high torque capabilities.
Shoulder bolts are another variety of close tolerance bolts that have a cylindrical shoulder between the head and the threaded shaft. As such, they are commonly used in applications where precise spacing or rotational movement is required. That last type we will cover is the countersunk bolt, which has a flat head with a cone-shaped underside, making it ideal for applications where a flush surface is desired.
Installation and Application
Threaded holes play a vital role in close tolerance bolt applications. These holes are tapped or formed to match the threads of the bolt. The threads of the hole ensure a secure and tight fit, preventing the bolt from rotating or coming loose. To ensure a proper connection, it is crucial to accurately match the thread specifications of the bolt and the threaded hole.
Close tolerance bolts find applications in various industries, including aerospace, automotive, electronics, and manufacturing sectors. In aerospace settings, these bolts are used to secure critical components that require high precision and reliability. Similarly, the automotive industry relies on close tolerance bolts for engine assembly, chassis components, and other structural applications. In electronics manufacturing, close tolerance bolts are used to secure delicate components and ensure proper grounding.
When selecting close tolerance bolts, it is essential to consider factors such as material, size, thread pitch, and strength requirements. These bolts are available in different materials, including stainless steel, alloy steel, and titanium, each offering specific properties suited to different environments. Please keep in mind that the size and thread pitch should match the requirements of the application, and the strength of the bolt must be sufficient to handle the anticipated loads.
