Minerallac 59020J – Frequently Asked Questions

1) What size hole do I drill for a 1/4 inch hammer drive anchor, and how deep does it have to go?
The Minerallac 59020J nail-in anchor is 0.25 inch in diameter, so it drops into a 1/4 inch hole drilled with a carbide bit. Minimum embedment is 0.875 inch, and the anchor's overall length is 1.250 inch, so the hole has to be deeper than the fixture thickness plus that 7/8 inch of grip. Drill past the embedment depth so dust at the bottom doesn't stop the pin from seating flush.
2) Can I use these hammer drive anchors overhead for hanging conduit or strut?
No. Minerallac specifically warns these zamac drive anchors are not recommended for overhead installations or vibrating loads. For overhead conduit, strut, or anything that sees machinery vibration, use a mechanical expansion anchor or a screw anchor rated for that service. These are for light duty wall and floor work in solid concrete, brick, and block.
3) Will these anchors hold in hollow block or drywall?
They are meant for solid base material: solid concrete, solid brick, and block or masonry walls. The zamac body expands against the sides of the drilled hole, so it needs solid material around it. In a hollow cell of a CMU, or in drywall, there is nothing to expand against, so use a toggle or a hollow wall anchor there instead.
4) Can I load the fixture right after driving the anchor?
Yes. Nail-in drive anchors like the 59020J reach full holding as the pin is hammered home, so there is no cure or set time. Drill, insert, drive the pin flush, and the connection carries load immediately. That is the main reason crews use them for termination bars and light strapping instead of adhesive anchors.
5) Are Minerallac zamac drive anchors okay in damp locations?
The zinc alloy body carries a zinc plated finish for corrosion resistance, which handles typical interior and sheltered damp conditions. For direct exposure to weather, chlorides, or chemical wash down, step up to a stainless fastener instead; zinc plating is a sacrificial coating, not a stainless substitute.
6) Is the Minerallac 59020J sold loose or in a jar, and how many come in it?
Model 59020J ships as a 100 piece pack, jar packaged, all one size at 1/4 inch by 1-1/4 inch. There is a single model on the item, so there is nothing else to specify beyond quantity of jars.
