Minerallac 60128NDJ – Frequently Asked Questions

1) What size hole do I drill for a Minerallac 3/16 inch concrete screw?
Drill 5/32 inch. The Minerallac 60128NDJ concrete screw ships with a matching 5/32 inch x 3-1/2 inch carbide-style drill bit, so the pilot hole size is settled in the box. Drill deeper than the 1-3/4 inch screw length so dust has somewhere to go, which the 3-1/2 inch bit length allows for.
2) Will a hex washer head concrete screw sit flush, or does it stand proud of the surface?
It stands proud. Head height is 0.187 inch and the washer flange is 0.308 inch across, so the head bears on top of the material rather than countersinking. That's what you want for conduit straps, strut, panel feet and equipment bases. If you need a flush finish in the surface, use a flat or countersunk head screw instead.
3) Can I use these blue concrete screws in a damp basement or parking garage?
The steel screw carries a blue anti-corrosion coating for moisture and environmental exposure, which suits damp interior work like basements, mechanical rooms and covered garage ceilings. For permanent exterior or chemically aggressive exposure, a stainless or heavier-coated anchor is the safer call.
4) Are these concrete screws suitable for mounting electrical panels and conduit straps to block walls?
That's their main use. Minerallac lists electrical panel and conduit mounting, HVAC equipment, and general structural and equipment anchoring in concrete and masonry. The hex washer head bears directly on one-hole straps, strut backing plates and panel mounting ears without extra washers.
5) Do I need a plastic anchor or shield with these screws?
No. These are self-tapping concrete screws, so they cut their own thread in the drilled hole and go straight into concrete or masonry with no sleeve, shield or plug. Drill 5/32 inch, blow out the dust, drive the screw.
6) How many Minerallac 60128NDJ concrete screws come in a jar, and is the bit included with every jar?
Model 60128NDJ is packed 100 screws to a jar and includes one 5/32 inch x 3-1/2 inch drill bit per pack. One bit per 100 screws, so on a large job order spare bits separately since masonry bits wear.
