M3 x 18mm Hex Socket Cap Screw (DIN 912) | Marine Grade A4 Stainless Steel

Providing a robust option for pump and valve assemblies, this M3 x 18mm counterbore cap screw is built with a 0.50mm metric thread and Fully Threaded threaded length for reliable engagement.

Because it uses an internal hex drive, this screw can be tightened cleanly in recessed areas and offers reliable fit in precision assemblies during securing drive housings. It can also be specified as a replacement machine screw where Dimensions are required.

Common Applications

  • Plant machinery service work
  • Conveyor frame assembly
