The Red Head LDT-1240 Large Diameter Tapcon anchors are 1/2-inch by 4-inch hardened carbon steel fasteners designed to cut their own threads into concrete. Featuring a zinc-plated, flanged hex washer head with anti-rotation serrations, these anchors install quickly using standard ANSI carbide drill bits, eliminating the need for nuts or washers. Engineered for superior pullout resistance and closer edge spacing, they deliver high load capacity in shallow embedments, making them the go-to choice for efficient, reliable concrete fastening.
