Minerallac 18813J – Frequently Asked Questions

1) Do Minerallac #8 x 3/4" sheet metal screws need a pilot hole in duct or enclosure sheet metal?
These are Type-A thread screws, which are self-tapping and cut their own threads in sheet metal without pre-drilling. On thicker or harder stock a pilot hole helps, but for standard duct gauge and enclosure steel you drive them straight in with a #2 driver.
2) Is a pan head the right choice, or do I need a flat head that sits flush?
Pan head sits on top of the material, not down in it. Head height is 0.115 inch and head width 0.322 inch, so it gives a broad bearing surface that spreads load on thin metal and will not pull through. If the surface has to be truly flush, as under a gasket or a sliding part, you want a countersunk flat head instead with a countersunk hole.
3) Will a 3/4 inch screw be long enough for mounting straps and boxes to a metal stud?
Overall length is 3/4 inch, which covers a strap or bracket plus the stud flange. It is a two-layer sheet metal fastener, not a framing screw, so if you need to pass through thick build-ups like multiple spacers or wood blocking, step up to a longer screw.
4) Can I drive these Minerallac screws with a slotted screwdriver, or do I need Phillips?
Either. The head is a Phillips/slotted combo drive, so a #2 Phillips bit or a flat blade both engage it. Handy on service calls where you are working one-handed in a panel and only have one driver on you.
5) Are zinc plated screws okay for rooftop HVAC and exterior siding work?
The steel body carries a zinc plated finish, which handles general indoor and sheltered conditions and resists everyday corrosion. For permanent exposure to weather, coastal salt air, or wet mechanical rooms, zinc plating is the wrong spec and you should be on stainless or a coated exterior fastener.
6) Can these screws be used to fasten into steel plate or structural steel?
No. Type-A threads are formed for sheet metal, not for thick steel. Beyond light gauge material the screw will not form a thread and will snap or spin out. For heavier steel use a self-drilling tapping screw rated for the thickness, or drill and tap for a machine screw.
7) How many Minerallac 18813J screws come in a jar?
Model 18813J is packaged 100 to a jar in the #8 x 3/4 inch size, which is a sensible shelf quantity for a service van or an MRO crib where you are grabbing a handful per job rather than ordering by the thousand.
8) What is the thread size on these #8 screws, and will they bite in thin gauge metal?
Thread size is 15 threads per inch on a #8 diameter, Type-A form. That coarse, widely spaced thread is what lets the screw grab in thin sheet stock with only a thread or two of engagement, which is exactly where a fine machine thread would strip out.
