S-92820A340 M6 x 30 mm High-Strength Metric Steel Serrated-Flange Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating, extending service life in harsh industrial environments.
• High tensile strength of 130,000 psi ensures reliable, heavy-duty fastening for demanding applications.
• Secure anti-loosening performance due to serrations under the flange, maintaining joint integrity under vibration.
• Easy installation and removal with external hex drive and standard M6 hex head, compatible with common tools.
• Precise Class 6g thread fit guarantees consistent engagement and reduces the risk of cross-threading.
• Flanged design eliminates the need for separate washers, speeding up assembly and distributing load effectively.
• Full threading along the 30mm length provides maximum grip and adjustability in various material thicknesses.

Professional Applications & Engineering Value

Engineered for industrial and heavy-duty applications, these M6 hex head screws deliver exceptional reliability where vibration resistance and strength are critical. The black-oxide steel material, combined with a Rockwell C27 hardness, offers excellent durability against wear and environmental exposure, reducing maintenance frequency. The flanged design with serrations locks securely into place, preventing loosening in machinery, automotive assemblies, and structural frameworks. With a coarse metric thread (M6x1 mm) and Class 6g thread fit, these screws ensure quick, precise installation in metals and composites, streamlining production while meeting rigorous performance standards.

Specification Summary & Compliance

This screw features a metric M6x1 mm coarse thread with Class 6g tolerance for precise fit, a flange diameter of 14.2 mm, and full threading over the 30 mm length. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial use.
