Mantus Anchors are designed to guarantee a set every time. Formed out of high quality steel plate. Contains no cast parts. Shank and shank boot are welded from top and bottom. Shank and roll bar are bolted to the fluke. ASTM certified steel bolts are oversized with a large margin to ensure safety. Although the shank is attached to the fluke with 4 bolts, a single bolt has sufficient strength to handle the maximum expected load on the anchor. In the carbon steel version every part of the anchor system is hot-dipped galvanized for corrosion protection (All shanks are HT ASTM 514 Steel and Flukes are mild steel A36 equivalent). Sharp-headed nose is precision machined to achieve the perfect chisel shape to achieve maximum penetrating power.
