Product Description

The M16-65 half thread bolt is a high-strength External hex bolt half threaded designed for secure fastening in heavy-duty applications. Featuring a partial threaded shank (thread length approximately 33mm) and smooth shoulder section, this Half threaded M16 hex bolt complies with DIN 931 standards, with a total length of 65mm and M16×2 thread pitch. The external hexagon head requires a 24mm wrench for installation. Constructed from grade 8.8 carbon steel with optional zinc plating or dacromet coating, it operates effectively in temperatures ranging from -50°C to +150°C. Widely used in structural engineering, machinery assembly, and automotive manufacturing, its hybrid design combines the vibration resistance of full-thread bolts with the alignment precision of shoulder bolts. The half-thread configuration enables optimal load distribution while allowing slight positional adjustments during installation. Primary advantages include corrosion resistance and 800 MPa tensile strength, though installation requires proper torque control to prevent thread damage. Typical applications involve connecting steel beams, securing industrial equipment, and mounting heavy components where both clamping force and shear strength are critical.
