Specification

Description

10.9 Grade Carbon Steel Flange Bolts are high-strength fasteners designed for demanding applications. These bolts are made from carbon steel, which is known for its durability and strength. The "10.9" grade indicates a specific level of mechanical properties: the first number (10) represents 1/100 of the nominal tensile strength in MPa, and the second number (9) indicates the ratio of yield strength to tensile strength, multiplied by 10. This means these bolts have a tensile strength of approximately 1000 MPa and a yield strength that is 90% of this value.

Flange bolts feature a flange at the head, which acts as a wide bearing surface and helps distribute the load more evenly across the connected materials. This design is particularly useful in applications where vibration or dynamic loads are present, as it reduces the risk of loosening. These bolts are commonly used in automotive, construction, and heavy machinery industries where reliability and load-bearing capacity are critical.
