I am looking to purchase some zero clearance plates (not manufacture my own). I looked all over on the web (ryobi / sears) and the t-nuts site which shows they sell them but no luck. Any ideas ??????
The sears picture has a four hole set up vs. the three on the saw. Do you have to tap them out to a four screw set up as other people described when making there own ??? I wanted the easy path to screw it down and cut cut cut away...
The BT3100 has four threaded holes; the BT3000 has two threaded and two smooth-bore holes. The Ryobi ZCTP package (part no. 4070333) includes a one-inch long thread-cutting screw to tap the two smooth-bore holes on a BT3000, along with four flat-head screws to secure a ZTCP.
Thanks everyone ... I did a search and found OEM on e-bay. Hopefully they have the thread cutting screw that Lowell was describing. I also sent a PM to Joey ...

The Screw that's included with the ZCTPs is a "Thread Forming Screw", not a Thread Cutting Screw.
The difference is that the Thread Forming Screw does NOT make chips like a Thread Cutting Screw does. The Screw is Tri-lobular, with an #8-24 x 1" thread form that EXTRUDES material to form the threads.
You could cut your own threads if necessary, using a regular Thread Cutting Tap, but it would make shavings that you would have to clean up to protect the guts of your Saw.
A set of taps from Harbor Freight are nice to have anyway and will take care of this in a few minutes. I thought the threads on my BT3100 were partially formed - the hole did not seem smooth but it did not readily take a screw either. A quick run through with a tap and everything was fine. You can also get individual taps of higher quality at Lowes or Home Depot.
