DIN 933 ISO 4017 Zinc Plated High Tensile Hex Head Bolts Grade 8.8 10.9 12.9 Fully Threaded Carbon Steel Fasteners

Product Description

DIN 933 ISO 4017 zinc plated high tensile hex head bolts are fully threaded carbon steel fasteners designed for strong, stable, and reliable mechanical connections. The bolts feature a standard hexagonal head, full machine thread, and blue-white zinc plated surface, making them suitable for machinery, automotive parts, structural steelwork, equipment assembly, and general industrial fastening applications.

These hexagon bolts are available in high tensile strength grades 8.8, 10.9, and 12.9. The full thread design provides a wider fastening range and allows strong clamping performance in metal-to-metal and hardware assembly applications. The hex head structure allows easy installation with standard spanners, sockets, or wrench tools.

The zinc plated coating gives the bolt a clean silver appearance and provides basic corrosion protection for normal indoor and dry environment use.
