Grade B7 Stainless Hex Cap Screws

A Grade B7 hex head cap screw, also known as a Grade B7 bolt, is a specific type of high-strength threaded fastener. It is made from alloy steel that has been quenched and tempered to achieve high tensile strength and hardness. Grade B7 hex head cap screws are typically used in high-temperature and high-pressure applications, such as those found in the oil and gas industry. Key characteristics of Grade B7 hex head cap screws include: Material: They are typically made from AISI 4140 or 4142 steel, which is alloyed with chromium and molybdenum for enhanced strength and corrosion resistance. Heat Treatment: Grade B7 fasteners undergo heat treatment processes, including quenching and tempering, to achieve the desired mechanical properties. Thread Design: These screws have UNC (Unified National Coarse) threads and are commonly available with a hexagonal head for wrench or socket installation. High Strength: Grade B7 hex head cap screws are known for their exceptional tensile strength and resistance to fatigue, making them suitable for critical applications. They are commonly used in flanged joints and other high-stress environments where temperature and pressure conditions demand a robust and reliable fastening solution. Additionally, they are often used in conjunction with Grade 2H heavy hex nuts to ensure proper performance and safety.
