If in doubt run a pilot hole so be sure the screw positions the clip tight into the groove. If you feel the clip is not tight and the gap setting is wider that is should be then it means the screw has self drilled off from the tight position. Sometimes you pay need a 4mm drill bit into thicker steel.

Always test the drilling into metal first as some metals used for joists vary a lot in hardness EXAMPLE BOX STEEL IS HARDER THAN ROLLED GAL.– use the 3mm drill bit provided as your pilot hole if you encounter self drilling issues. Always run tests before you start the deck and do not hesitate to call Deck-Max and ask any questions.

DO NOT OVER TIGHTEN SCREWS – FIRM AND SECURE INTO THE REBATE OF THE BISCUIT.

This screw is not a surface fix screw.

No.1 problem with fixing is the installer can break the screw off when using an impact driver and not know until after the job is completed and the board wants to cup as the screw had broken during installation.

Solution : Do not use rattle guns as they keep driving – Some people can adjust but rattle guns are typically the # 1 problem and breaking screw heads.

Broken screws void any warranty claim in any way.

COMBO PACK – DM 4154 – OF 2 X 100mm # 2 square drive bits. – Ideal so your vision is improved as the tip is clear of the chuck providing superior drill & eye coordination.

Purchases of extras are often required when screws are damaged or lost – because the screw count equals the biscuit count often screws are dropped on the ground, left in nail bags etc, then simply buy an extra pack as required.
