S-90605A169 M6 x 30 mm DIN 912, ISO 4762 Left-Hand Threaded Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength for demanding applications with Class 12.9 rating and 170,000 PSI tensile strength, ensuring reliable performance under high stress.
• Superior corrosion resistance provided by the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
• Precise, secure fastening with left-hand threads for specialized assemblies where reverse threading prevents loosening from counter-rotational forces.
• High durability and wear resistance due to Rockwell C37 hardness, maintaining integrity through repeated use and high-torque installation.
• Optimized for efficient installation with a standard 5 mm hex drive and socket head, allowing for high torque application in confined spaces.
• Reliable dimensional accuracy with Class 5g6g thread fit and partial threading, ensuring consistent engagement and reduced risk of cross-threading.
• Compliance with global standards including DIN 912/ISO 4762, RoHS 3, and REACH, guaranteeing quality and environmental safety for international projects.

Professional Applications & Engineering Value

This M6 x 1mm left-hand thread socket head cap screw is engineered to address critical challenges in heavy-duty and precision assemblies. The black-oxide alloy steel construction provides excellent resistance to corrosion and wear, making it ideal for machinery, automotive, and aerospace applications exposed to high stress and environmental factors. The left-hand thread design is specifically valuable in systems where rotational motion could loosen standard right-hand fasteners, such as in certain motors, presses, or conveyor systems. With a Class 12.9 strength rating and 170,000 PSI tensile strength, it ensures joint integrity in high-vibration environments, reducing maintenance needs and downtime. The hex socket drive and 5 mm drive size facilitate secure, high-torque installation with standard tools, enhancing assembly efficiency and reliability in confined spaces.

Specification Summary & Compliance
