The 3 8 bolt, also known as the 3/8 inch bolt, is a type of fastener commonly used in various industries, including construction, automotive, and manufacturing. This bolt is characterized by its 3/8 inch diameter and is often used to join two or more parts together. The 3 8 bolt is available in different lengths, thread types, and materials, making it a versatile fastener for various applications.
Technical Specifications of 3 8 Bolts
Understanding the technical specifications of 3 8 bolts is crucial for selecting the right fastener for a particular application. Some of the key specifications to consider include the bolt’s diameter, length, thread type, and material. The 3 8 bolt has a diameter of 0.375 inches, which is equivalent to 9.53 mm. The length of the bolt can vary, ranging from 1⁄4 inch to several inches, depending on the specific application. The thread type of the bolt is also important, with common thread types including coarse thread, fine thread, and left-hand thread.
Materials Used for 3 8 Bolts
3 8 bolts are made from a variety of materials, each with its own unique properties and advantages. Some of the most common materials used for 3 8 bolts include stainless steel, galvanized steel, and aluminum. Stainless steel bolts are known for their corrosion resistance and are often used in applications where exposure to moisture or chemicals is a concern. Galvanized steel bolts, on the other hand, are coated with a layer of zinc to provide corrosion protection and are commonly used in construction and manufacturing applications. Aluminum bolts are lightweight and corrosion-resistant, making them ideal for use in aerospace and automotive applications.
| Material | Tensile Strength | Yield Strength |
|---|---|---|
| Stainless Steel | 70,000 - 100,000 psi | 30,000 - 50,000 psi |
| Galvanized Steel | 60,000 - 90,000 psi | 30,000 - 50,000 psi |
| Aluminum | 30,000 - 60,000 psi | 10,000 - 30,000 psi |
