Schraubstock-Montageset, 3/8" T-Nut

Popped the swivel base off my vise and these 5/16"-18 studs fit perfectly into the 3/8" T-slots on my workbench. The two-inch length gives me just enough thread engagement to really lock things down tight without bottoming out.

Finally, a mounting kit that doesn't require extra trips to the hardware store. The 5/16"-18 studs fit perfectly into my vise's T-slot, and I love that the 2-inch length gives me plenty of room to tighten everything down securely. It's a solid upgrade over the makeshift bolts I was using before.

These studs are exactly 2 inches long, so they grip the 3/8" T-slot firmly without bottoming out. I had to pop the swivel base off first, which took a minute, but once that's done the vise locks down rock solid.
