Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 PSI ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from zinc-plated alloy steel construction prolongs service life in harsh industrial environments.
- High hardness rating (Rockwell C39) provides excellent wear resistance, maintaining thread integrity through repeated use.
- Precision 90° countersink angle allows for flush mounting, creating smooth surfaces and improving aesthetic finish.
- Fully threaded M6x1mm coarse pitch design delivers faster installation and superior holding power in various materials.
- 4mm hex drive compatibility enables secure tool engagement and efficient torque application during assembly.
- Compliance with DIN 7991 standards guarantees consistent quality and dimensional accuracy for engineering applications.
Professional Applications & Engineering Value
Engineered for demanding industrial applications, these Class 12.9 flat head screws combine zinc-plated alloy steel construction with fully threaded M6x1mm coarse pitch design to solve critical fastening challenges. The 90° countersink angle ensures seamless flush mounting in precision machinery, automotive assemblies, and heavy equipment where surface protrusions are unacceptable. With 170,000 PSI tensile strength and Rockwell C39 hardness, these metric hex drive screws withstand extreme vibrational loads and prevent stripping in high-torque scenarios. The right-hand thread configuration provides familiar installation while the zinc plating offers essential corrosion protection for outdoor or chemically exposed environments, making them ideal for structural applications requiring both strength and durability.
Specification Summary & Compliance
These M6 flat head screws feature Class 5g6g thread fit tolerance for precise engagement and 8mm length with fully threaded design. Manufactured to DIN 7991 specifications for dimensional consistency and performance reliability. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industries without hazardous substance restrictions.
