Minerallac 79224J – Frequently Asked Questions

1) Do I need to pre-drill before driving Minerallac #12-14 Tek screws into metal?
No pre-drilling. These are self-drilling Type-BSD fasteners, so the point cuts its own hole and the thread engages in one pass through metal substrates. That is the whole point of a Tek screw on metal-to-metal work like duct hangers, strut, and enclosure assembly.
2) What driver or bit do I need for these hex washer head Tek screws?
A hex driver, not a Phillips or square bit. The head is a hex washer head measuring 0.309 across and 0.303 high, so a standard magnetic hex nutsetter in a drill or impact driver runs them. The washer face spreads the load on sheet metal instead of pulling through.
3) Are zinc plated Tek screws okay outdoors or in a damp mechanical room?
The screws are steel with a zinc plated finish, which gives corrosion resistance for general interior and protected exterior use. Zinc plating is a sacrificial coating, not stainless, so for direct weather exposure, coastal air, or wash-down areas expect a shorter service life and spec a stainless or coated-for-exterior fastener instead.
4) Will a #12-14 Tek screw work for hanging electrical boxes and HVAC equipment off metal studs or ductwork?
Yes, that is the intended use. The #12-14 diameter with Type-BSD self-drilling thread is sized for metal-to-metal fastening, and the stated applications include HVAC equipment installation, electrical enclosure assembly, metal building construction, and industrial equipment mounting. The hex washer head seats flat against a bracket or flange without needing a separate washer.
5) Can I use these Tek screws in wood or drywall instead of metal?
Not the right fastener for it. A Type-BSD self-drilling point is made to cut metal; in wood or gypsum it has no holding power worth relying on and the washer head will spin through soft material. Use a wood screw or a drywall anchor for those substrates and keep these for metal-to-metal connections.
6) How many screws come in a pack of Minerallac 79224J Tek screws?
They are packed 100 per pack, which is the quantity to count on when you are figuring out how many packs a job needs. Both the 1-1/2 inch and 2 inch versions carry Minerallac part numbers 79224J and 79232J respectively, so order by those numbers to keep the right length on the truck.
