    M12 x 20mm Fully Threaded Metric Hexagon Head Bolt – Class 8.8, Zinc Plated Yellow Passivated – DIN 933 / ISO 4017

    Product Description:

    Enhance the integrity of your assemblies with our premium M12 x 20mm Fully Threaded Metric Hexagon Head Bolts. Engineered to meet DIN 933 and ISO 4017 standards, these bolts are crafted from high-strength Class 8.8 steel and feature a zinc-plated yellow passivated finish for superior corrosion resistance.

    Key Features:
