The M53248 TorqueMaster Large Diameter Tapcon (3/8" × 3") is a heavy-duty concrete screw anchor designed for fastening structural components directly into concrete, brick, or masonry block. Its large-diameter thread profile cuts into the base material, creating strong holding power without the need for expansion anchors or additional hardware. The hex washer head provides a wide clamping surface, helping distribute load and maintain secure fastening during installation. Simply drill the pilot hole and drive the anchor—a fast and reliable method when solid masonry anchoring is required. In other words, it’s the kind of fastener that bites into concrete and settles in like it owns the place.
