S-93339A205 M6 x 10.8 mm Set Screws

Key Features & Benefits at a Glance

• Superior holding power thanks to alloy steel construction and Rockwell C39 hardness for reliable, long-term fastening in demanding environments
• Precise and secure fit with Class 6g thread tolerance, ensuring consistent performance and ease of assembly in metric applications
• Enhanced grip and reduced component damage from the ball tip design, which minimizes stress concentration on the contact surface
• High torque application capability with the 3 mm hex drive, allowing for secure installation and removal with standard tools
• Optimized for coarse thread applications with a 1 mm pitch, providing faster installation and strong resistance to vibration loosening
• Space-saving headless design ideal for confined spaces where a flush or low-profile finish is required
• Environmentally responsible manufacturing with RoHS 3 compliance, meeting strict EU regulations for hazardous substances

Professional Applications & Engineering Value

This M6 set screw is engineered to solve critical fastening challenges in industrial settings. The alloy steel core, hardened to Rockwell C39, provides exceptional shear and tensile strength, preventing failure under high dynamic loads. Its ball tip distributes clamping force evenly, protecting precision-machined components from indentation and galling—common issues with standard set screws. The Class 6g metric thread ensures a precise fit with mating parts, reducing the risk of cross-threading in automated assembly lines. Paired with a hex drive for high torque transmission, this headless set screw is a trusted solution for securing gears, pulleys, and collars in machinery, automotive, and automation systems where vibration resistance and reliability are non-negotiable.

Specification Summary & Compliance

This set screw adheres to metric (M6 x 1 mm) specifications with a Class 6g thread fit for standard tolerance applications. The manufacturing process ensures dimensional accuracy for the 10.8 mm length, 3 mm hex drive, and 4 mm ball tip diameter. It is RoHS 3 (2015/863/EU) compliant under exemption 6(a) for lead as an alloying element in steel, confirming its suitability for regulated markets and environmentally conscious engineering projects.
