M12 x 70mm Flanged Hex Head Bolt (DIN 6921) | A4 Stainless Steel

The M12 x 70mm A4 Stainless Steel flanged hex head bolt is chosen for conveyor frames where a standard hex bolt would need extra load spreading. Its 70mm thread length, 1.75mm pitch and 11.5mm head height make it easy to match with existing DIN 6921 fastener specifications.

The built-in washer face helps protect the surrounding surface, making the fixing useful for equipment that sees vibration, routine servicing or repeated adjustment. The A4 Stainless Steel finish should be matched to the working environment before installation.

Common Applications

  • Conveyor Frames: joining brackets on conveyor frames and handling systems.
  • Panel Mounting: reducing the need for loose washers on flat surfaces.
  • Workshop Use: supports firm alignment where vibration or movement can affect standard fasteners.
  • Trade Maintenance: supporting quick specification from thread size and length.
