Carbon Steel Alloy Steel Slotted Hex Head Bolts , #12 - 24 M10 Phillips Hex Flange Screw
1. Description:
Serrated hex flange bolts have a ridge or skirt (flange) around the bolt head that distributes the clamping load when the bolt is tightened. The flange works like a washer. Flange bolts are sometimes called frame bolts.
The most common hex serrated flange bolts are zinc plated and the stainless steel hex flange bolts is the choice which no need to coating to read corrosion resistance, and so as to the carbon steel which go through the heat treatment to achived the higher grade and hight tensile. and the serrated flange keep the fastening from sliding while in high vibration.
The normal bolt is very thick, difficult to deformation, if the vibration occurs after fixing, which need to be re-tighten. However the hexagonal flange bolt with which a thin flange portion, that may be slightly deformed, it can fastened the connection more strongly.Once fastened in the hole, there may be no way to use ordinary bolt tool. but the small head of flange bolts, the flange also play a role in following tightening, that is because it can go to a dedicated tool hole. and hex bolts may by go under the same principles. and the serrated flange which acts as an integrated not washer, which serves to distribute the pressure of the nut, to reducing the chance of damage to the part and making it less to loosen as a result of an knurled fastening surface.
