Minerallac 77008J – Frequently Asked Questions

1) Do I need to pre-drill before driving these Minerallac #10 sheet metal screws?
No pilot hole is needed in sheet metal. These are Type-A thread self-tapping screws, so the point cuts its own thread as you drive it. Steady downward pressure while turning clockwise is what gets the threads to bite; stop once the hex washer head seats so you don't strip the hole.
2) What driver do I need for these hex washer head screws, and can I use a screwdriver instead of a socket?
Either works. The head is a Phillips/slotted combo, so a #2 Phillips bit drives it in tight spots, and the 5/16 inch hex washer head takes a 5/16 inch socket or magnetic hex driver when you want more torque and less cam-out. On overhead duct work most crews run the 5/16 hex and keep a #2 Phillips for screws you can't get a socket onto.
3) What lengths do the Minerallac #10 self-tapping sheet metal screws come in?
Two lengths: 1/2 inch (part 77008J) and 2 inch (part 77032J). The 1/2 inch is the everyday duct and enclosure screw where you are joining two thin sheets. Go to the 2 inch when you have to reach through insulation, a standoff, or a thicker build-up to get to the metal behind it.
4) Are these #10 screws OK outdoors or in a damp mechanical room?
The screws are steel with a zinc plated finish, which handles indoor humidity and damp mechanical rooms. Zinc plating is a sacrificial barrier coating, not stainless, so for direct weather exposure, coastal air, or anything in standing water you want a stainless or coated exterior fastener instead.
5) Will a hex washer head screw pull through thin gauge duct or a panel cover?
That is exactly what the washer head is for. The integral washer under the hex gives a wider bearing surface than a plain hex or pan head, spreading the clamp load so the screw does not dish or pull through thin sheet. Head width is 0.312 inch with a head height of 0.34 inch, so it sits proud of the surface rather than countersinking, which is fine on duct seams and enclosure covers but not where you need a flush face.
6) What is the thread count on these #10 self-tapping screws?
Thread size is 16, so #10-16, which is the coarse self-tapping thread pitch used for sheet metal rather than a machine-screw pitch. That means they will not thread into an existing #10-24 or #10-32 tapped hole in a panel or box; for those you need a machine screw of the matching pitch.
7) Can I use these Minerallac screws to mount electrical enclosures and panels?
Yes, enclosure and panel mounting is one of the intended uses, along with HVAC ductwork, sheet metal fabrication and repair, building maintenance, and equipment housings and covers. The Type-A self-tapping thread is meant for sheet metal, so it is the right screw for attaching to a box flange, a strut cover, or a metal housing, not for structural fastening into wood or concrete.
8) How do these Minerallac sheet metal screws come packaged for a service truck?
They ship in jar packaging, which is what most service techs want on the truck or in a van bin, since you can scoop a handful without the bag splitting. Part 77008J is the 1/2 inch jar and 77032J is the 2 inch jar.
