Reverse/Left hand threaded bolts

[Roboteernat]

Had update from our work suppliers...

The cost of the bolts for 100 25mm, 100 30mm and 100 35mm bolts came to a price of around £1400, as these are usually custom made to order. This was a quote from a very large supplier too. I guess thats the reason they cost so much!

Im going to get an M5 lh die and machine my own from M6 bolts i think...
Will see if i can do it and maybe have some to sell...
