INCRA 0.5mm Mechanical Pencil
0.5mm Mechanical Pencil for all INCRA Precision Rules & Layouts.
As you see above, the micro-fine guide holes on INCRA rules are designed for a perfect mark with the .5mm lead size in your mechanical pencil. This design elevates the inexpensive .5mm pencil into a precision marking and layout instrument. All of the marking holes in INCRA rules require the .5mm size.
Some pencils on the market have .7mm lead, but these will not work in our precision marking holes.
Pencil design may vary from photo.
