About this item:
- 12.70mm Chrome Alloy Screw (Chassis) Punch
- A screw punch, also known as a chassis punch or a knockout punch, is used to punch a hole through sheet metal.
- First drill a pilot hole in the sheet metal the same size as the bolt in the punch.
- For sizes 13mm and under a Twist drill may be used.
- For larger sizes use a Bordo step drill.
- Place the die on to the bolt and then insert this assembly through the pilot hole.
- Wind the punch onto the bolt and tighten by hand until firm.
- Turn hex head of bolt with a socket, spanner or wrench until the punch is drawn completely through the sheet metal.
