M4 x 20mm Hex Countersunk Screw ISO 10642 | A4 Stainless Steel
Where general engineering work requiring balanced engagement and clamping are required, this M4 x 20mm hex countersunk screw provides a machine-thread fastening solution. The combination of 0.7mm pitch, 8.96mm head diameter and ISO 10642 specification gives this size its own performance profile.
A4 stainless steel (316 marine grade) is selected for marine, coastal and chemically exposed installations. The 2.48mm head height and H2.5 hex socket drive are specific to this variant, supporting controlled torque transfer. Unlike smaller or larger thread sizes, the M4 format is commonly specified for light fabrication work, control panels and small brackets.
