This bolt set is a pack of 20 high-strength metric flange bolts (often meeting DIN 6921 standards) designed for heavy-duty automotive, machinery, and DIY applications

• Thread Size (M8-1.25): 8 mm nominal body diameter with a 1.25 mm coarse thread pitch.
  
  
• Length (30mm): 30 mm measurement from under the head to the tip of the bolt.
  
  
• Full Thread: Threads run the entire length under the head for maximum grip and adjustment flexibility.
  
  
• Class 10.9 Alloy Steel: High-tensile structural steel (around 1,040 MPa tensile strength) built to handle high stress, torque, and vibration.
  
  
• Black Zinc Plated: Provides a corrosion-resistant and rust-retardant dark finish.
  
  
• Flanged Hex Head: The built-in circular washer-like flange under a 13 mm external hex head spreads the clamping load over a wider surface, preventing damage or marring to soft parts and reducing loosening from vibration
