S-91290A064 M18 x 160 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance under extreme loads, minimizing the risk of fastener failure in critical applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life and reducing maintenance needs in harsh industrial environments.
• High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity and drive features through repeated use and high torque.
• Precise Class 5g6g thread fit guarantees smooth assembly and secure fastening, reducing installation time and improving joint reliability.
• Optimized for high-torque applications with a 14mm hex drive and standard socket head profile, allowing for easy installation and removal with common tools.
• Versatile partially threaded design offers a non-threaded shank for precise clamping, ideal for applications requiring alignment or shear strength.
• Compliance with major international standards including DIN 912/ISO 4762, ensuring interchangeability and meeting rigorous quality expectations for global projects.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this M18 socket head cap screw delivers critical performance where failure is not an option. The black-oxide alloy steel construction combats corrosion effectively, making it suitable for machinery, automotive assemblies, and construction equipment exposed to moisture and chemicals. Its Class 12.9 strength rating and coarse thread (2.5mm pitch) provide superior clamping force and vibration resistance, preventing loosening in dynamic environments. The partially threaded 160mm length allows the unthreaded portion to act as a precision dowel, enhancing alignment in fabricated structures and reducing stress concentration. By integrating high tensile strength with a durable hex drive, this screw simplifies maintenance and ensures long-term reliability in demanding engineering contexts.
