S-90128A266 M6 x 30 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 in high-stress applications, reducing the risk of fastener failure.
• Superior hardness (Rockwell C37) provides excellent wear resistance and durability, extending service life in demanding environments.
• Zinc-plated alloy steel construction offers enhanced corrosion resistance, protecting against rust and maintaining integrity in harsh conditions.
• Precise Class 5g6g thread fit guarantees smooth installation and secure fastening, minimizing assembly time and improving joint reliability.
• 5 mm hex drive with standard socket head allows for easy access and high torque application in confined spaces, enhancing installation efficiency.
• Partially threaded design enables optimal grip and clamping force distribution, ideal for applications requiring precise unthreaded shank sections.
• Compliance with DIN 912/ISO 4762 standards ensures dimensional accuracy and interchangeability, supporting global engineering specifications.

Professional Applications & Engineering Value

This M6 socket head cap screw is engineered to address critical challenges in heavy-duty industrial settings, such as machinery assembly, automotive systems, and construction equipment. The Class 12.9 strength rating and zinc-plated alloy steel material provide robust resistance to dynamic loads and environmental corrosion, preventing loosening under vibration and extreme conditions. With a coarse thread pitch of 1 mm and right-hand thread direction, it ensures quick installation and reliable holding power in high-stress joints. The partially threaded rod type allows for precise clamping in applications where unthreaded sections are necessary to avoid thread damage, making it a versatile choice for engineers seeking durability and compliance with international standards like DIN 912 and ISO 4762.

Specification Summary & Compliance

This screw adheres to precise dimensional tolerances, including a Class 5g6g thread fit per metric standards, ensuring consistent performance. It meets DIN 912 (identical to ISO 4762) for socket head cap screws, covering head profile, drive size, and thread specifications. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming it is free from hazardous substances and suitable for environmentally conscious industrial applications.
