Metallics TEKD6AL-10M – Frequently Asked Questions

1) Do these self-drilling screws need a pilot hole?
No pilot hole needed. The TEKD6AL-10M is a self-drilling and tapping screw with a #4 drill point, so it bores and threads in a single pass. Keep steady pressure and a moderate RPM so the point cuts rather than burnishes.
2) Will a #10 x 3/4 in. self-drilling screw hold in sheet metal, or do I need something longer?
At 3/4 inch overall length in a #10 diameter, the TEKD6AL is sized for thin material: sheet metal, light gauge framing, and strapping where the drill point can break through and the threads engage on the far side. If your combined stack is thicker than about half the shank, the point consumes the length before the threads bite and you want a longer screw.
3) Why would I use an aluminum self-drilling screw instead of a steel one?
Aluminum is the material here, and the usual reason to specify it is to avoid galvanic corrosion when the fastener sits in aluminum work: aluminum trim, aluminum siding, aluminum framing members. A steel screw in aluminum sets up dissimilar metal contact. The tradeoff is that aluminum is a softer fastener than steel, so it is not the choice for drilling heavier gauge steel.
4) What driver size do the Metallics TEKD6AL self-drilling screws take?
The TEKD6AL-10M takes a 5/16 inch hex driver. The head is an indented hex with a hex drive, so a 5/16 nut setter in a drill or impact driver runs them. No bit changes, no cam-out concerns like a Phillips head.
5) Is the washer built into the Metallics TEKD6AL screw or separate?
The washer comes with the screw, so you are not stocking a second line item. It spreads the clamp load under the 5/16 indented hex head, which matters when you are fastening thin sheet or strap that a bare head would dimple or pull through.
6) Can I use these Metallics screws for electrical strut, strap and box mounting?
That is the intended lane. The TEKD6AL-10M is catalogued for electrical work and the #10 x 3/4 size with a hex head and washer is the common fastener for securing straps, clips, small boxes and light brackets to thin metal. For anchoring into concrete or masonry you need a different fastener entirely, since a drill point screw will not hold there.
7) What is the exact part number for the #10 x 3/4 aluminum hex head TEK screw with washer?
Metallics TEKD6AL-10M. One model, one configuration: #10 diameter, 3/4 inch length, 5/16 indented hex head, #4 drill point, aluminum, with washer. There are no finish or size options to specify on it.
