It will require M5 and M3 SHCS to secure the Hiwin and THK rails to the 1530 series 8020 extrusions. Some of the more typical hardware used with 8020 is their economy T-nuts. Since the size I require is not offered I made the decision to create my own. It's very straight forward. A simple matter of a few cut fender washers, hex nuts, and a bit of tack welding. Split lock washers will be located under the head of the SHCS in the rail itself. We will see if this arrangement maintains a tight screw or requires frequent attention. |
