Who It's For

The anchors are best for professionals and DIYers who need a dependable anchor for concrete only, especially where exposure to water or humidity is expected, such as mounting HVAC equipment, securing outdoor structures, or fixing railings to concrete decks. The package quantity of 100 also makes this a practical choice for larger jobs or stock for a tradesperson.
