This 4.8 x 9.5mm six lobe pan head self-tapping screw is manufactured to ISO 14585-C in A2 stainless steel (304 grade). ISO 14585-C specifies a pan head self-tapping screw driven by a six lobe recess, forming its own thread with high torque transfer. The hardened thread cuts its own path into a pilot hole while the six lobe recess grips over a larger area than a cross recess, resisting cam-out under powered assembly.

Typical applications

  • Powered assembly into sheet, board, and plastics
  • Enclosure, ducting, and panel work
  • Production lines where cam-out slows fitting
  • Maintenance where fixings are removed repeatedly

Available in packs of 25 to 200, with free next working day delivery on UK orders over £50 and 30-day returns.

How do I choose between A2 and A4 stainless steel?

A2 (304) stainless steel suits most indoor, outdoor and workshop jobs. Choose A4 (316) marine grade for coastal, marine, poolside or other chloride-rich environments.

How do I make sure I order the right size?

Check the size in the product title and the standard, material and dimensions in the Product Specification tab. In M8 x 30, M8 is the thread diameter and 30 is the length in millimetres. See our size guide if you need more help.
