Our little M-4 Speed Nuts made changing templates so much faster and easier than the square nuts we used for years so we designed an XL version M-6 nut to work on the table and template holder frame.

After initially trying mild steel, we decided to upgrade to EN24T heat treated steel with about 4X the tensile strength of mild steel. We also changed the shape to be even more user-friendly.  When used vertically, they fall right into the slots due to the offset hole. Be sure to see the mini-video about these nerdy new nuts!
