M12 x 40mm Hex Countersunk Screw ISO 10642 | A2-70 Stainless Steel

With a 40mm length, 1.75mm pitch and 26.88mm head diameter, this variant is optimised for equipment assemblies needing increased fastening depth while maintaining a flush countersunk finish.

Manufactured for engineering applications. The 7.44mm head height and H8 hex socket drive are specific to this variant, supporting controlled torque transfer. Unlike smaller or larger thread sizes, the M12 format is commonly specified for industrial plant equipment and heavy-duty engineering systems.
