I have a Craftsman plunge router, model 320.1740. It is the common one you see today in silver color 9.5 amps. I paid no attention to it years ago when it came. But it is missing the lock bolts as it is called in the parts manual. They are the ones the lock down the depth rod and the two that hold the rods for a guide if one is used. According to the parts they are all the same. Does anyone know what size screws they are. It looks like 3/16 diameter, but what size thread I need to know. Knowing my misfortune I will get the wrong screw. I called the parts department and I was told they are no longer made and she had no more info on it. I would like to get something with a knob on it as well if someone knows where to order three that will fit. Any info is greatly appreciated. Thanks
