Description

  • Thread Size: M12-1.75; Thread Part: 30mm; Unthreaded Part: 40mm; Thread Type: Partial Thread (leaving a smooth shank to prevent thread damage in holes, improve alignment accuracy, and reduce stress concentration)
  • Grade 10.9 High Tensile Strength – Heavy-Duty Reliability:Significantly stronger than standard Grade 8.8 bolts. Engineered for critical joints requiring maximum load-bearing capacity and resistance to shear forces in automotive, machinery, and structural applications
  • Integrated Flange with Serrated Underside – Vibration Resistance & No Washer Needed: Features a built-in flange face with radial serrations that bite into surfaces, preventing loosening under vibration or dynamic loads. Eliminates separate washers for faster installation, reduces part count, and distributes clamping force evenly to protect soft materials
  • Black Oxide Coating – Basic Corrosion Defense & Professional Finish: Treated with a uniform black oxide finish for moderate rust resistance in dry or indoor environments, enhanced surface lubrication during installation, and a clean, non-reflective black appearance. Surface is smooth and burr-free for safe handling and consistent performance
  • Rigorous Applications: Automotive, Machinery, Structural & DIY Projects;Trusted for high-stress applications: engine mounts, transmission brackets, agricultural equipment, steel frame connections, and heavy-duty DIY projects. Dimensions comply with metric standards (e.g., M8, M10) – verify size compatibility before purchase. Packaged in resealable bags with clear size labeling
