Look at McMaster Carr on the net. It's like a lag bolt on one end, machine screw on the other. Put a nut on the machine screw end and lock with (I prefer to drill and tap the side of the nut) cut off the excess length and slot. I usually put an internal tooth lockwasher on top the nut so the screw won't turn after it's adjusted and you are tightening the top nut. Use a thin (jam) nut for minimum thickness. In your case I would counterbore the rim to clear the nut and if necessary grind off the boss on the plate. Lots simpler than machining the head of the bolt. Any decent hardware store should have hanger bolts and acorn nuts as well. 3/4 c-bore 3/8 or 1/2 inch deep should do it. Nice to hear from you. Hi to Trix! Carl Meyer Ptg assoc Santa Clara, Ca. Carl ---I don't know bout you but grinding plate bosses is not my idea of time well spent. I get the drift . One thing though, how hard are these bolts & what do use to cut 13 plus slots in short order. ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
