Mack shutter screws 40 x 6 mm – black galvanised

These black, galvanised shutter screws are intended for fixing into timber. The Torx head gives extra grip when driving. The milled drill point reduces the risk of splitting and usually makes pre-drilling unnecessary. The serrated thread makes driving in easier and the flat head gives a neat finish.

NOTE

Check the exact screw length and thread diameter for your shutter material and profile.

Check whether matching plugs or washers are needed; these may not be supplied.

Use a suitable Torx bit; with soft timber, pre-drilling may still be needed depending on the type and condition of the wood.
