M12 x 40mm Flanged Hex Head Bolt (DIN 6921) | A4 Stainless Steel
This M12 x 40mm flanged hex head bolt in A4 Stainless Steel works well in installing brackets on stainless processing frames and washdown equipment. Manufactured to DIN 6921, it uses a 26.6mm flange diameter and 16mm across flats to give a practical hex driven fixing for food processing equipment.
The integrated flange acts like a built-in washer face, helping to spread clamp load and reduce surface marking on brackets, plates or fabricated parts. The A4 stainless steel material gives marine grade stainless protection while the DIN 6921 specification keeps the fastener compatible with standard metric assemblies.
Common Applications
- Food Processing Equipment: installing brackets on stainless processing frames and washdown equipment.
- Machinery Builds: supports tidy fastening where hygiene and maintenance access matter.
- Maintenance Work: replacing worn fixings during planned servicing.
- Fabrication: creating repeatable DIN 6921 joints across metal assemblies.
