    Characteristics of Eastech Nusantara's Bolt

    Standard Dimensions

    We provide precision products by manufacturing them in accordance with DIN, JIS, Komatsu, Hitachi, and Caterpillar standards.

    Fine Grade Steel

    Provides good hardenability, high tensile strength, and high impact resistance. It's suitable for heavy-duty and construction.

    Forged Head

    Provides proper flow of the steel, even distribution of weight, and reduces the fatigue points, which ensure major resistance.

    Coated Body

    We offer blue trivalent or black oxide coating that gives our bolts several benefits, including corrosion resistance, reduced friction, increased lifespan, and environmental compliance.

    Wide Variety of Sizes

    For better satisfaction, we are able to produce standard products from M24 to M30 and up to 130 mm in length. If you want a customized product, it's also possible to make it.

    Metric Bolt Grades
