Key things to remember

The essentials from this document in plain words. Check the full document before you rely on a figure.

  • Fits over the hex of AS 3566 self drilling screws into steel and timber, giving a permanent tamper-proof finish.
  • Mild steel, mechanical galvanised.
  • Two sizes: IRSMSGS031 for 10 gauge screws (5/16 inch driver) and IRSMSGS037 for 12 and 14 gauge screws (3/8 inch driver).
  • Set it with the IRSMSZTS-037 installation tool (zinc plated, for 1/4 to 3/8 inch hex screws).
  • Fit the screw first, centre the ring over the hex head, put the tool on top and hit it with a mallet. Keep going until the ring covers the hex and sits flush with the surface.

Who it helps: Builders and maintenance crews who need screw fixings that cannot be tampered with.
