Classic T-Nuts for building jigs and DIY machines.
This flavor of T-nut is a 1/4-20 and zinc plated. Price breaks are available for orders of increased quanity.
If you're not super familar with these little guys, you're in for a treat. These allow you to put threads into wood that won't wear out. Great for homemade and DIY woodworking jigs and machines.
I recomend finding the best fitting drill bit you can, you want a snug fit. Not all bits labeled the same size make the same sized hole! Drill your hole, then put some 2 part epoxy in it. Then hammer this bad boy home.
