Understanding M8 Hex Head Bolts Specifications and Applications

M8 hex head bolts are essential fasteners widely used across various industries due to their durability and reliability. The M in M8 refers to the metric system, indicating that the bolt has a nominal diameter of 8 millimeters. The hexagonal head allows for easy manipulation with a wrench or socket, making these bolts preferable in applications where tightening and loosening are required frequently.

Specifications of M8 Hex Head Bolts

M8 hex head bolts are typically made from different materials, including carbon steel, stainless steel, and alloy steel, each offering varying degrees of strength, corrosion resistance, and thermal stability. The most common grades for these bolts include Grade 8.8 and Grade 10.9, which are suitable for high-stress applications. Grade 8.8 bolts are medium carbon steel bolts with a minimum tensile strength of 800 MPa, while Grade 10.9 bolts are high-strength bolts with a minimum tensile strength of 1000 MPa.

The length of M8 bolts can vary significantly depending on the application, ranging from 20 mm to over 100 mm. They are also associated with various thread pitches; the common thread pitch for M8 bolts is 1.25 mm, though finer and coarser pitches are available for specialized applications.

Advantages of M8 Hex Head Bolts
