M8 x 40mm Flanged Hex Head Bolt (DIN 6921) | 8.8 Steel BZP
Use this M8 x 40mm 8.8 Steel BZP flanged hex head bolt when refreshing older machinery assemblies with DIN standard hardware require a hex head fastener with an integral bearing face. The 13mm across flats drive size supports installation with standard tooling.
The DIN 6921 form combines a hex drive with a wider seating face, helping to spread clamp load and reduce surface marking on brackets, plates or fabricated parts. The 8.8 BZP steel material gives 8.8 high tensile clamping strength while the DIN 6921 specification keeps the fastener compatible with standard metric assemblies.
Common Applications
- Plant Refurbishment: refreshing older machinery assemblies with DIN standard hardware.
- Machinery Builds: offers predictable dimensions for maintenance teams and purchasing departments.
- Maintenance Work: replacing worn fixings during planned servicing.
- Fabrication: creating repeatable DIN 6921 joints across metal assemblies.

Specification Notes
Select the material grade to suit the environment; A4 stainless is better for harsher exposure while BZP steel is best kept to dry or sheltered use. The flange helps spread pressure but the correct mating component is still important for safe installation.
