The entire anchor is covered with Stalgard GB (Galvanic Barrier) coating. These features make Aggre-Gator anchors virtually immune to hydrogen-assisted stress corrosion cracking. Alternating, hi-low notched threads provides quick cutting and stability during installation and hold tight in block and poured concrete.
