Micro Jig GRR-Ripper 3/16" Offset Oval Nuts
Whilst this is a spare part for the Micro Jig GRR-Ripper, they can also be used in conjunction with Micro Jig Thumb Screws (GRH-5-K or GRH-6-K) to fit into Torquata or Incra T-Track.
Sold as a pack of 10. The size of each nut is 11.1mm x 15.9mm x 2.5mm, with a 10-32 (3/16" 32 TPI) thread. These are so small that they can have a tendency to fall in from one side of the T-Track into the middle but when the thumbscrews are tightened the nut will lift up and seat itself under the lip of the T-Track correctly without pulling up.
