M4 x 18mm Hex Countersunk Screw ISO 10642 | A4 Stainless Steel
This ISO 10642 fastener uses an M4 thread combined with a 18mm length to suit general engineering work requiring balanced engagement and clamping. The 8.96mm head diameter allows the countersunk profile to sit neatly within prepared recesses on fabricated components.
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.
Common Applications
- light fabrication work, control panels and small brackets
- Machine and equipment manufacture
