Product Description

The M20x130 half thread hex bolt is an externally threaded fastener designed for robust mechanical connections, featuring a partial threading length and an external hexagonal head. This M20x130 half threaded hex bolt typically offers a thread length of approximately 60-70mm (depending on design specifications) and an unthreaded shank section for applications requiring precise alignment or shear resistance. With a nominal diameter of 20mm and overall length of 130mm, it conforms to ISO 4014/4017 standards for dimensions and material strength. The external hex head enables standard wrench or socket tool engagement. Manufactured from grade 8.8 carbon steel or A4-70 stainless steel, it operates within -50°C to +120°C environments, suitable for construction, machinery assembly, and structural frameworks. Advantages include high tensile strength (up to 800 MPa for grade 8.8) and corrosion resistance in harsh conditions, while the half-thread design may limit full-depth thread engagement in certain applications.
