S-93395A363 M6 x 25 mm DIN 7991 Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction with passivated finish
• Reliable high-strength performance with a tensile strength of 70,000 psi for demanding industrial applications
• Secure and flush installation enabled by the standard 90° countersink angle and flat head design
• Efficient assembly and disassembly with a 4mm hex drive that provides positive torque transfer and reduces tool slippage
• Consistent and precise thread engagement ensured by the Class 6g thread fit and fully threaded M6x1mm coarse thread design
• Broad industry compatibility and quality assurance through compliance with the DIN 7991 standard
• Safe for regulated applications with full compliance to RoHS 3 and REACH environmental directives

Professional Applications & Engineering Value

This M6 flat head screw is engineered from 316 stainless steel, offering exceptional resistance to chlorides and acidic environments, making it ideal for chemical processing, marine hardware, and food-grade equipment. The passivated finish enhances surface durability, preventing galling and further increasing corrosion resistance. Its fully threaded design with a coarse thread pitch ensures maximum grip and holding power in a variety of materials, from metal to hard plastics. The hex drive and flat head profile allow for a clean, flush finish in countersunk holes, which is critical for applications where protruding fastener heads are not permissible, such as in machinery guards, conveyor systems, and structural panels.

Specification Summary & Compliance

This metric screw features an M6x1mm thread with a Class 6g tolerance and is fully threaded. The head diameter is 12 mm with a tolerance of -0.43 to 0 mm, and the head height is 3.3 mm. It conforms to the DIN 7991 manufacturing specification and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
