Minerallac 79849J – Frequently Asked Questions

1) What thickness of drywall is a 3 inch screw meant for?
Three inches of length is far more than single layer board needs. A 3 inch #8 screw is for thick build-ups, double and triple layer drywall assemblies, or shooting through board into furring and framing behind it. For a single 1/2 inch sheet on wood studs, a 1-1/4 inch screw is the normal call; use the 3 inch where you need the extra embedment.
2) Will a bugle head screw tear the paper face on drywall?
No, that is what the bugle head is for. The curved underside of the head pulls the screw down and countersinks it flush with the board instead of punching through the paper facing, so you get a dimple you can tape and finish over. Head diameter is 0.339 inch and head height is 0.03 inch.
3) Are black phosphate drywall screws OK for outdoor or damp locations?
Keep them inside. Black phosphate is a mild corrosion resistant coating meant for concealed interior work, not a weather coating. For exterior sheathing, soffits, bathrooms with standing moisture, or anything in contact with treated lumber, use a screw with a coating rated for exterior exposure. These steel screws are for interior drywall assemblies.
4) What driver bit do I need for Minerallac 79849J drywall screws?
A #2 Phillips bit. That is the standard bit in any drywall gun or impact driver, so no special tooling and no adapters. Keep a spare bit on hand on a 100 count jar run, since Phillips recesses cam out as the bit wears.
5) Do I need to pre-drill for these screws?
No. The sharp point starts on its own in wood and in 25 gauge steel framing, so you drive straight through the board into the stud. Pre-drilling is only a consideration if you are hitting something heavier than the framing this screw is rated for.
6) How are these Minerallac drywall screws packaged for a jobsite?
They come as a 100 count jar under model 79849J. A jar is convenient for punch list and repair work out of a pouch rather than bulk hanging, so property maintenance crews can keep one in the truck for patch-ins on multi-layer or furred walls.
7) What does the 8-10 thread size mean on this screw?
It is the thread callout for the coarse drywall thread form used on this #8 x 3 inch screw, listed as 8-10. Practically, order and stock it as a #8 coarse drywall screw; the head takes a #2 Phillips and the shank diameter matches standard #8 drywall screw guns and bit holders.
