CNC Hold Down Clamp Set

This is a set of CNC hold down fixturing parts for use with a 2D CNC fixturing table that has 1/4 20 threaded inserts, 2.3" on center apart in a grid layout. Why 2.3"? Because it was a happy medium between the 3" on center layout I have used before where the holes were too far apart, and a 2" on center layout where I would have had to buy MANY more threaded inserts. The clips and clamps will work on any spacing, but the side rails won't.

The system is designed so that you can put down a corner panel and/or one or more side panels, flush your work piece up to it/them, then use the clips on top of the rail with a 1/4 20 screw (I prefer button head, hex drive bolts) going through the clip, through the rail, into the fixture table. The clamp pieces can then be used on the sides where you don't have a rail or corner installed. They have minimal overhang on to the work surface to minimize the chances of hitting them when you cut your projects.
