Veritas Bench Anchor

It is easiest to think of these as barrel-shaped insert nuts, except they self-anchor and are removable. Usable horizontally, vertically or at any angle in between, they accept common 1/2-13 threaded bolts and will wedge in through holes in material as thin as 5/8" (depending on the strength of the material) or in blind holes 1 1/4" deep.
