Flange bolts, as compared to regular bolts contain a circular washer like disk attached on the lower part of the head of the bolt. This circular flange in the Stainless Steel Flange Bolts eliminates the need to add another washer in the assembly.12 Point Flange Bolts Stainless Steel is used as a specialty fastener in the oil and gas industry due to the recessing head, which is not visible when the ends of the bolts are clamped together.
Often, Serrated Stainless Steel Flange Bolt Material is used in various applications including its use in vehicle frames, especially in trucks. These serrated Stainless Steel Flange Head Bolts dig into the surface thereby reducing the fastener from becoming loose. Because the Stainless Steel Hex Head Flange Bolts features a nozzle, it reduces the time and hence is resultant in speeding up the assembly by eliminating the washer.
Those Stainless Steel Hex Flange Bolts that do not have serrations are known as frame bolts.
As opposed to a standard hex screw, Stainless Steel Metric Flange Head Bolts render four times the bearing area. This bearing area ensures smooth distribution of securing pressure.
