Hex Head Bolt – A4-70 Stainless Steel (DIN 931)

NOTE: DIN 931 has been withdrawn and replaced by ISO 4014. There is some similarity (nominal dimensions extended | Widths across flats changed for M10, M12, M14 and M22).

These DIN 931 Hex Head Bolts are manufactured from A4-70 stainless steel and feature a partially threaded design with an unthreaded shank.

A4 stainless steel provides excellent corrosion resistance, making these bolts particularly suitable for demanding environments where exposure to moisture, weather or corrosive conditions is a consideration.

The DIN 931 partially threaded design provides an unthreaded shank between the thread and bolt head, making these bolts suitable for applications where the shank passes through components or where a partially threaded fastener is preferred.

The external hexagon head allows straightforward installation using standard spanners and sockets.

Ideal for fabrication, automotive, machinery, engineering, outdoor equipment, marine environments, maintenance and general workshop applications requiring a strong, corrosion-resistant stainless steel fastener.

Available individually from Shores NZ, so you can buy exactly what you need with no minimum order quantity.
