M3 x 10mm Hex Countersunk Screw ISO 10642 | A4 Stainless Steel

The M3 thread size makes this ISO 10642 hex countersunk screw particularly suitable for compact electronics, instrumentation panels and precision housings. With a 10mm length, 0.5mm pitch and 6.72mm head diameter, this variant is optimised for compact installations where only limited thread engagement is needed while maintaining a flush countersunk finish.

A4 stainless steel (316 marine grade) is selected for marine, coastal and chemically exposed installations. The 1.86mm head height and H2 hex socket drive are specific to this variant, supporting controlled torque transfer. Unlike smaller or larger thread sizes, the M3 format is commonly specified for compact electronics, instrumentation panels and precision housings.

Common Applications

  • compact electronics, instrumentation panels and precision housings
  • Machine and equipment manufacture
  • Engineering and fabrication projects
  • Maintenance and repair operations
