S-95942A126 M6 x 16 mm Left-Hand-Thread Stainless Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh or humid industrial environments.
• Enhanced torque application and strip-resistance provided by the 4mm hex drive, ensuring secure and easy installation.
• Reliable performance under load due to a high tensile strength of 80,000 psi and Rockwell B85 hardness.
• Secure fastening in reverse-thread applications with the left-hand thread direction, preventing loosening from counter-clockwise motion.
• Maximum grip and holding power from the fully threaded design, distributing stress evenly along the entire 16mm length.
• Consistent and precise fit ensured by the Class 6g thread fit, reducing the risk of cross-threading and assembly issues.
• Compliance with strict environmental regulations, being RoHS 3 and REACH compliant for safe and sustainable use.

Professional Applications & Engineering Value

This M6 left-hand thread screw is engineered to address specific industrial challenges where standard right-hand threads would loosen under reverse rotational forces. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it a durable choice for machinery, automotive assemblies, and outdoor equipment exposed to the elements. The rounded button head and hex drive offer a low-profile, aesthetically clean finish while allowing for high-torque installation in confined spaces. Its fully threaded metric design with a coarse 1mm pitch ensures quick assembly and robust clamping force, critical for maintaining integrity in high-vibration environments. This combination of a left-hand thread and robust material solves the engineering need for reliable, non-loosening fasteners in specialized mechanical systems.

Specification Summary & Compliance

This screw features an M6 x 1mm thread with a Class 6g tolerance for precise fit. It is manufactured to standard metric dimensions with a length of 16mm, a head diameter of 10.5mm, and a fully threaded shank. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial components.
