S-91294A424 M14 x 70 mm DIN 7991, ISO 10642 Alloy Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 120,000 psi ensures reliable performance in high-stress industrial environments, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide finish on alloy steel extends service life and maintains integrity in harsh conditions.
• High hardness rating of Rockwell C32 provides excellent wear resistance, minimizing deformation under heavy loads.
• Precise Class 6g thread fit with coarse 2mm pitch allows for quick, secure installation and vibration resistance in demanding applications.
• Fully threaded design offers consistent gripping power along the entire 70mm length, enhancing joint stability.
• Standard 90° countersink angle and flat head profile enable flush mounting, improving safety and aesthetics in assembled products.
• Compliance with DIN 7991/ISO 10642 standards guarantees dimensional accuracy and interoperability in global engineering projects.

Professional Applications & Engineering Value

This M14 flat head screw is engineered to address critical challenges in heavy-duty industries, such as machinery assembly, automotive frameworks, and structural steel connections. The black-oxide alloy steel construction combats rust and oxidation, ideal for environments exposed to moisture or chemicals. With a Class 10.9 strength grade and coarse metric thread (2mm pitch), it delivers high clamp load and rapid installation, reducing downtime in production lines. The hex drive style (10mm) ensures easy torque application with standard tools, while the fully threaded right-hand design provides uniform stress distribution, preventing loosening under dynamic loads. This screw is a dependable choice for applications requiring robust, long-lasting fastening solutions that meet rigorous industrial standards.
