Serrated Flange Bolt: 5/16-18 UNC, 3" Length Under Head, Fully Threaded MPN:824161MSC

Serrated flange bolts are widely utilized for applications involving high vibrations or slippage where standard hexagon bolts can be loose under extreme conditions. The serration on these bolts creates additional holding power by gripping into the holes, hence providing a better clamping mechanism than regular hex bolts. Additionally, they have raised countersinks which prevent water from getting trapped at the bottom of the hole thereby decreasing corrosion chances in wet environments; further features include being fully threaded with 5/16-18 UNC right hand threads and having a length of three inches under its head. They are most ideal for industries involving machinery, automobiles, construction or heavy equipment where the bolts are subject to stress or strain which may compromise the integrity of regular bolts but this serrated flange bolt offers maximum security.
