M20 x 30mm Hex Socket Cap Screw (DIN 912) | Marine Grade A4 Stainless Steel

Frequently specified for agricultural equipment, this M20 x 30mm socket cap screw uses a cap head profile and socket drive to support accurate tightening in serviceable assemblies.

The cap head design gives useful bearing surface beneath the head, helping deliver solid bearing area beneath the head in fitting support plates. A4 stainless steel is often chosen for external, marine and washdown environments where improved corrosion resistance is needed.

Common Applications

  • Maintenance replacement fixings
  • Aluminium profile assembly
  • Marine hardware installation
  • Fabrication workshop projects
