Self Drilling Screws - Hexagon Cover Caps
In this section you will find a range of different colours of hex head cover caps for our hexagon head self-drilling screws. The caps push onto the hexagon and over the washer (if there is one).
All of our cover caps are suitable for either the 16mm or 19mm bonded washers but are also suitable to use in applications where no washer has been used.
What’s the difference between self drilling and self tapping screws?
A self drilling screw drills its own hole and cuts its thread in one go. A self tapping screw cuts a thread but needs a pilot hole first.
Do self drilling screws need a pilot hole?
No — the drill point makes its own hole as you drive it. Only very thick or hard steel at the top of a point’s range needs a pilot, or a step up to a bigger point.
What size self drilling screw do I need for metal?
Match the drill point to the total thickness of steel you’re fixing through, using the drill-point guidance above.
