Minerallac 39915 – Frequently Asked Questions

1) How much weight will a Minerallac 39915 self-drilling drywall anchor hold?
Holding capacity depends on how thick the board is: 40 lbs in 3/8 inch drywall, 50 lbs in 1/2 inch, and 75 lbs in 5/8 inch. Minerallac also flags these anchors as not for life safety or overhead applications, so keep them to vertical wall loads like devices, brackets and fixtures.
2) Will these Minerallac anchors work in 1/2 inch drywall, or do I need a toggle?
The 39915 anchors are rated for 3/8, 1/2 and 5/8 inch gypsum wallboard, and in 1/2 inch board they carry 50 lbs. If your load is heavier than that, or you are fastening into plaster or a solid substrate, a toggle bolt or a masonry anchor is the right call instead. These are hollow wall anchors only.
3) What exactly comes in the Minerallac 101 piece drywall anchor kit?
Fifty zinc alloy self-drilling anchors, fifty #8 x 1-1/4 inch pan head square/Phillips sheet metal screws, and one #2 x 2 inch hex power bit. That is everything needed to install out of the box, nothing else to buy.
4) Can I use these anchors to hang a TV bracket or overhead conduit support?
No. Minerallac states these are not for life safety or overhead applications, and even at best they carry 75 lbs in 5/8 inch board. TV brackets and anything suspended overhead belong in studs, blocking or structure with a rated anchor.
5) Do I need to drill a pilot hole for these self-drilling drywall anchors?
No pilot hole. The anchor point drills its own hole in gypsum board as you drive it, so you can set it with a Phillips screwdriver or with the included hex power bit in a drill. That is the practical difference from a plastic expansion anchor, which needs a drilled hole sized to the anchor first.
6) How thick a fixture can I mount with the #8 x 1-1/4 inch screws in this kit?
Maximum fixture thickness is 3/4 inch. Past that the 1-1/4 inch screw does not have enough thread left in the anchor body. If you are stacking a thicker bracket or a mounting plate plus a spacer, step up to a longer #8 sheet metal screw and keep the same anchor.
7) What size is the Minerallac 39915 anchor itself, and how deep does it go into the wall?
Anchor size is 1/2 x 1-5/8 inches. That length is what has to clear behind the board, so make sure there is open cavity behind the mounting point, not a stud face, a pipe or a conduit run.
8) Can these Minerallac anchors be backed out and reused if I move a fixture?
The anchors are removable, so you can pull the screw and back the anchor out to reposition a fixture or swap it. Relocating usually means a fresh anchor in undisturbed board rather than reseating the old one in the same hole.
9) Are these drywall anchors corrosion resistant enough for a damp utility room?
Construction is a zinc alloy anchor body with a zinc plated carbon steel screw, which handles normal interior humidity. Zinc plating is not a marine or exterior coating, so for washdown areas or anything outdoors use a stainless fastener system.
10) Will a square drive bit work on these screws, or is it Phillips only?
The screws take either. They are a square/Phillips pan head, so a #2 square or a #2 Phillips bit both drive them, which is handy if your crew is already set up with square drive on the impact.
11) Is the Minerallac 39915 anchor kit made in the USA?
Yes, the 39915 kit is manufactured in the United States, which matters if you are working a job with domestic sourcing requirements.
