These 3/8' Sanko drop - in anchors are perfect for heavy - duty concrete applications. You get 50 concrete anchors in a box. Sanko is the most trusted name in core drilling anchors. A recent study found they're 15% stronger than the competition. They're super versatile, working with bolts and threaded rods of any length. For a flush finish, drill the hole the same length as the anchor; drill deeper for more embedment in masonry projects. If you don't need the anchor anymore, just plug or fill with cement to smooth the surface. We recommend using our setting tool for proper installation. The values on the chart are average ultimate values and are just a guide, not guaranteed. A 4:1 safety factor, or 25%, is generally a safe working load.

Remember, these anchors are great for heavy - duty concrete work. A safety factor of 4:1 (25%) is generally a safe working load, and the concrete compressive strength should be 2,987 psi. The values on the chart are just a guide, not guaranteed. If you no longer need the anchor, simply plug or fill the hole with cement to make the surface smooth again. There's no special maintenance required for these anchors. Just keep them in a dry place when not in use.
