DIN 931 & 933 Hex Bolts (ISO 4014/4017) - JTE Saudi

Engineered for structural integrity, these hexagon head bolts conform to the updated ISO 4014 (DIN 931) and ISO 4017 (DIN 933) standards. The transition from DIN to ISO specifications includes critical adjustments to the across-flats dimensions for M10, M12, M14, and M22 sizes to ensure compatibility with modern fastening systems. Available in high-tensile carbon steel grades 8.8 and 10.9, as well as corrosion-resistant A2 and A4 stainless steel, this range covers a wide spectrum of industrial and construction requirements.

Key Features & Specifications

• Standards Compliance: Fully aligned with ISO 4014 (semi-full thread) and ISO 4017 (full thread) specifications.
• Material Grades: Offers high-strength Class 8.8 and 10.9 for structural loads, and A2/A4 stainless for corrosive environments.
• Dimensional Accuracy: Accounts for the specific across-flats changes in M10, M12, M14, and M22 sizes mandated by the ISO revision.
• Head Type: Standard hexagon head for optimal torque application and wrench access.

Applications

These bolts are essential for heavy-duty machinery, civil engineering structures, bridges, and general fabrication where reliable joint strength and precise fitment are paramount. The stainless variants are ideal for outdoor installations, marine environments, and food processing industries where rust prevention is critical.
