Generally, jig accessory kits all come with UNC threads. Not a problem until you need to connect them something else, which you can guarantee will turn out to be metric. To avoid this potential frustration, we are offering an ALL METRIC jig making kit. Every thread is M6, male and female. This 118-piece kit comprises 26 female knobs in 4 different styles, all with through threads. These range from 50mm diameter large lobed to small 25mm diameter knurled knobs. There are 10 male knobs in 2 sizes along with 16 each of pronged T-nuts and threaded inserts, and 20 washers. The T-slot bolts come in 3 lengths: 10 x 25mm, 10 x 50mm and 10 x 75mm. The T-slot bolts fit directly into the UJK Technology Track and Stop Kit, the UJK Universal T-Track as well as the T-Track on the UJK Router Fence and they will also fit similar 1/2" T-tracks. A good strong box keeps the bits and pieces organised and ready for use.
We also sell a UNC kit, item No. 950114.
