Specification

Description

8.8 Grade Carbon Steel Machine Screws are a type of high-strength fastening hardware commonly used in industrial and construction applications. These screws are made from medium carbon steel that has been quenched and tempered to achieve a tensile strength of 800 MPa and a yield strength of 600 MPa, as indicated by the "8.8" grade designation. The first digit (8) represents 1/100 of the nominal tensile strength in MPa, and the second set of digits (0.8) indicates the ratio of yield strength to tensile strength.

These screws feature a threaded shaft designed for precise engagement with matching nuts or tapped holes, ensuring secure and reliable connections. They are typically zinc-plated or coated to enhance corrosion resistance, making them suitable for outdoor or harsh environments. 8.8 Grade Carbon Steel Machine Screws are versatile and widely used in automotive, machinery, structural engineering, and general manufacturing due to their robust mechanical properties and ease of installation.
