S-91290A883 M30 x 90 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional durability and strength with a tensile strength of 170,000 psi and Rockwell C37 hardness, ideal for high-stress applications.
• Superior corrosion resistance provided by the black-oxide finish on alloy steel, extending service life in harsh environments.
• Precise and reliable fastening due to the Class 5g6g thread fit and coarse 3.5mm pitch, ensuring secure connections with minimal risk of loosening.
• Easy installation and removal with a standard 22mm hex drive and socket head design, allowing for high torque application in confined spaces.
• Full thread engagement across the 90mm length, offering maximum grip and load distribution in demanding assemblies.
• Compliance with international standards including DIN 912/ISO 4762, RoHS 3, and REACH, ensuring safety and environmental responsibility.
• Versatile for heavy-duty use in machinery, automotive, and construction, thanks to its metric M30 size and high-strength Class 12.9 rating.

Professional Applications & Engineering Value

This M30 socket head cap screw is engineered from black-oxide alloy steel to address critical industrial challenges, such as vibration-induced failures and corrosion in aggressive settings. Its fully threaded right-hand design with a coarse 3.5mm pitch ensures rapid assembly and robust load-bearing capacity, reducing downtime in applications like heavy machinery, automotive frames, and structural supports. The Class 12.9 strength and precise Class 5g6g thread fit provide reliable performance under extreme tensile and shear stresses, while the hex drive facilitates efficient installation with standard tools. By meeting DIN 912/ISO 4762 standards, it guarantees interchangeability and safety, making it a trusted choice for engineers seeking durability and compliance in metric fastening solutions.
