S-91294A328 M10 x 20 mm DIN 7991, ISO 10642 Alloy Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional strength and durability with Class 10.9 rating and 120,000 psi tensile strength, ensuring reliable performance in high-stress applications.
• Superior corrosion resistance thanks to the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
• Precise and secure fastening with M10x1.5mm coarse thread and Class 6g fit, providing excellent grip and vibration resistance.
• Easy installation and removal using a standard 6 mm hex drive, reducing assembly time and tooling requirements.
• Optimal flush mounting with a standard flat head and 90° countersink angle, creating a smooth surface finish.
• Consistent quality and compliance meeting DIN 7991/ISO 10642 standards, ensuring interchangeability and reliability.
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, supporting sustainable procurement practices.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these M10 flat head screws combine black-oxide alloy steel and Class 10.9 strength to address common challenges like joint failure under heavy loads and corrosion in exposed conditions. The fully threaded coarse pitch design ensures maximum holding power in metals and composites, while the hex drive allows for high-torque installation without slippage. Ideal for machinery, automotive assemblies, and structural frameworks, these screws deliver long-term reliability by maintaining Rockwell C32 hardness and dimensional stability, reducing maintenance needs and downtime in critical operations.
