• Enhanced durability and wear resistance from Rockwell C37 hardness, ensuring long-term reliability under repetitive loads.
• Accurate fit and interchangeability guaranteed by compliance with DIN 912/ISO 4762 standards and Class 5g6g thread fit.
• Versatile fastening solution with a 200 mm partially threaded design, allowing flexibility in clamping and alignment adjustments.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, this M42 socket head cap screw addresses critical challenges in heavy machinery, automotive assembly, and construction equipment. The black-oxide alloy steel construction provides a protective layer that combats corrosion and reduces galling, essential for outdoor or humid conditions. With a coarse thread pitch of 4.5 mm and right-hand thread direction, it ensures rapid installation and high resistance to vibration loosening, minimizing maintenance downtime. The 32 mm hex drive and standard socket head profile facilitate precise torque control in confined spaces, enhancing safety and efficiency. Ideal for applications requiring high tensile strength and durability, such as structural frames and power transmission systems, this fastener delivers consistent performance under extreme mechanical stress.
