Description
The DIN65438 Aerospace Bihexagonal Head Bolts are high-performance fasteners designed for close tolerance, high load capacity, and thermal resistance in aerospace and critical engineering applications. Manufactured with a bihexagonal head for secure grip and torque efficiency, these bolts feature an MJ-thread (a fine-pitch aerospace standard metric thread) and a short thread length optimized for lightweight structural designs.
Crafted from titanium alloy, these bolts offer a nominal tensile strength of 1100 MPa and withstand temperatures up to 315 °C, making them ideal for demanding thermal and mechanical environments such as aircraft assemblies and high-temperature mechanical systems. Additional material options include carbon steel and stainless steel in standard strength grades (4.8, 8.8, 10.9, 12.9) for broader industrial use.
A variety of protective finishes are available, including plain, black oxide, zinc electroplating, hot dip galvanizing, copper plating, nickel plating, and zinc impregnation, enhancing corrosion resistance and surface durability.
Fully compliant with DIN65438, these bolts are also available in conformity with GB, ISO, ANSI/ASTM, BS, JIS standards. OEM customization is welcome based on customer drawings or physical samples. Free samples are provided for quality evaluation.
Packaging options include wooden boxes, pallets, cartons, plastic bags, and nylon bags for secure and professional delivery.
