Metallics TEKDHH7B – Frequently Asked Questions

1) What steel thickness will a #3 drill point self-drilling screw actually drill through?
The Metallics TEKDHH7B is rated for panel thicknesses of 0.110 to 0.175 inch, which is roughly 12 to 8 gauge steel. Below 0.110 inch the #3 point is more drill than you need and a #2 or #1 point screw is the better choice; above 0.175 inch the point will stall before it taps clean threads.
2) How many Metallics TEKDHH7B screws come in an order?
These ship in boxed quantities with a 10,000 piece order minimum, which is a bulk thousand-count buy rather than a shop pack. If you need a smaller count, ask about other sizes and quantities, which Metallics offers by request.
3) What does the high hat washer head on these Metallics self-drilling screws do for me?
The integral washer head spreads bearing load over a 0.364 to 0.414 inch outside diameter, so it seats flat against sheet metal, strut, or a panel without pulling through or dimpling the material. No separate washer to stock or drop on the roof. It is not a sealing washer, so it does not substitute for a bonded EPDM washer on a weather-exposed deck.
4) Are these Metallics TEKDHH screws Buy American and ARRA compliant for a federal job?
Both the Buy American and ARRA compliance flags are marked compliant on the TEKDHH7B. Country of origin is listed as multiple, so if your contract requires a specific origin on the certified mill paperwork, get that confirmed against the lot you receive.
5) Is a zinc plated self-drilling screw okay for outdoor or damp locations?
Zinc plated steel is a dry-interior and protected-location finish. It handles indoor electrical work, strut, panels, and framing fine, but on a roof, a coastal site, or anywhere with standing moisture the plating is cut through at the drill point as it cuts, and corrosion starts there. For exposed work, specify a stainless or coated-head drill screw instead.
6) Does a self-drilling screw like this need a pilot hole?
No. The Type BSD drill point cuts its own hole and taps the thread in one pass, which is the whole point of the design. Keep steady pressure on the driver as it starts, since the head is designed for maximum drilling engagement so the bit does not slip off as you drive.
7) How much does a full box of these #10 x 1 inch drill screws weigh?
A box runs 77 lbs, measuring 11.5 x 11.5 x 10.75 inches. Plan the hand truck, not the tool bag, if you are moving the full 10,000 count minimum onto a floor.
