Clean out hole prior to fixing screw – sand surface smooth to clean up any surface splinters.

Do not over tighten the screw or you will break the underside of the decking. Always run a second drill bit to set the depth of the screw

When starting the hole scribe the surface first then apply downward pressure to cut hole – this will prevent chipping of the surrounding surface.

When replacing the drill bit and BEFORE you loosen the grub screws cut a fine mark on the collar of the BORE section so you will have a precise mark to re set the outer crown back onto the Bore after the drill bit is refitted.

Use when preparing the face fixing for the Composite Fascia or any boards that require face fixing.

Be careful if the underside of the screw is notched as it will start to cut the pre cut groove once it hits depth. (maybe set the hole a little deeper) so the screw sits flush to the surface before is starts to bush the hole.
