Before I drill into underlying retaining screws, thought I would get some information from this group. I have layed out the pre cut and pre drilled MDF on my waste board. Best i can tell, the predrilled retention screw holes in the T Track kit line up with the retention holes in the waste board. #1 Am I correct in this observation? Assuming that’s the case, #2 Should I remove the M5 retention screws from the main waste board and replace with longer M5 screws? I’m guessing I will need M5 x 44+(or whatever length is recommended) if this is best practice?? If some one with experience or Will Adams can give me a recommendation, it would be greatly appreciated. I hope I can find these bolts locally at big box. Also, should these be flat head or what head configuration?
Thanks for reading and in advance for any help you can provide
