8.8 Steel Hex Cap Screws

A Grade 8.8 hex head cap screw is a high-strength fastener made from carbon steel and is part of a metric grading system. The "Grade 8.8" designation signifies the screw's tensile strength, which is approximately 800 megapascals (MPa) or 116,000 pounds per square inch (psi). These screws are widely used in various industries, including automotive, machinery, and construction, where reliable and robust fastening is essential. Key characteristics of Grade 8.8 hex head cap screws include: Material: They are typically made from medium carbon steel, ensuring high tensile strength and durability. Metric Grading: Grade 8.8 is a metric designation, with the first number indicating the material's tensile strength and the second number representing the ratio of the yield strength to the tensile strength. Thread Design: These screws have metric threads and hexagonal heads, making them compatible with metric hardware and tools. Grade 8.8 hex head cap screws are known for their excellent strength and reliability in various applications. They are commonly used in machinery, automotive assembly, and construction projects, providing secure and durable fastening solutions in high-stress environments.
