M5 x 20mm Flanged Hex Head Bolt (DIN 6921) | A4-70 Stainless Steel

This M5 x 20mm flanged hex head bolt in A4-70 Stainless Steel provides a strong fastening option for assembling support frames, ducts and service housings. Manufactured to DIN 6921, it uses a 11.8mm flange diameter and 8mm across flats to give a practical hex driven fixing for HVAC equipment.

This one-piece flange design reduces loose hardware so the fastener can seat cleanly against flat or slotted components. Its 5.4mm head height and 11.8mm flange diameter should be checked against the available clearance before final selection.

Common Applications

  • Hvac Equipment: assembling support frames, ducts and service housings.
  • Frame Assembly: helps maintain a broad bearing face on thin sheet or bracketed materials.
  • Service Panels: creating a neat fixing for removable covers.
  • General Engineering: standardising parts around the DIN 6921 format.
