S-90854A329 M27 x 90 mm ISO 4017, DIN 933 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional Load-Bearing Capacity – Class 10.9 strength grade and 150,000 psi tensile strength ensure reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior Corrosion Resistance – Zinc yellow-chromate plating provides a durable barrier against rust and environmental degradation, extending service life in harsh industrial settings.
• Optimized Thread Engagement – Coarse 3mm pitch and Class 6h thread fit offer quick assembly and secure fastening, minimizing loosening under vibration.
• High Durability & Wear Resistance – Rockwell C32 hardness ensures the screw maintains its integrity and dimensional stability under repeated loads and abrasive conditions.
• Broad Industrial Compatibility – Fully threaded M27 design with external hex drive allows for versatile use across machinery, structural frameworks, and heavy equipment.
• Certified Quality Assurance – Compliance with ISO 4017/DIN 933 standards guarantees consistent dimensions, thread accuracy, and manufacturing reliability for global projects.
• Efficient Installation & Removal – External hex head (41mm width, 17mm height) enables easy torque application with standard tools, speeding up maintenance and assembly processes.

Professional Applications & Engineering Value

Engineered for demanding environments, these M27 hex head screws address critical challenges in heavy machinery, construction, and industrial assembly. The high-strength steel core, combined with a zinc yellow-chromate finish, resists corrosion in humid or chemically exposed settings, preventing premature degradation. The coarse metric thread (3mm pitch) and Class 6h fit ensure rapid installation and vibration-resistant connections, reducing downtime in automated systems. With full threading and an external hex drive, they provide uniform clamping force and easy access in confined spaces, making them ideal for structural supports, equipment frames, and automotive components where reliability under dynamic loads is paramount.

Specification Summary & Compliance
