b) Mekhahlelo ea mantlha ea ho cheselletsa flash butt ke:

Sethala sa Flash: ho lokisa bolelele ba ho otlolla, ho boloka lebone, lebelo la flash, letsoalo la hona joale;

Mokhahlelo o holimo oa ho qhekella: tumello ea ho forging e holimo, lebelo le holimo la ho forging, khatello e holimo ea forging, clamping force;
