Hexagonal bolts are usually formed with cold heading. The process is classified as open-die forging and therefore its die design is less complicated. The mushroom-like head has to be sheared into hexagonal shape and the amount of the scrap is somehow significant especially for heading with short bolts or high alloy material. There is an increasing demand in increasing the gross profit by increasing the yield of workpiece material.

六角螺栓头端通常以冷间顶铁成形製程来製造，由於冷间顶铁属於开模锻造，模具设计较容易，但需以剪缘模再对蕈状头端冲剪成为六角头，此剪缘后的废料量不容忽视，尤其对於长度较小的螺栓，或其它应用於紧扣件的高级合金而言，藉由减少废料以提高產品毛利的需求日益迫切。
