As you can see (hopefully) the acme style screw threads have a rather
wide "flat" at the top and bottom of each thread. This dramatically
increases the strength of the threads compared to regular V-point
types.
Where to see 'em? MOST wood and metal vises use acme for the main
screw, or Go to harbor freight or home depot and look at Jorgenson
brand "Pony" pipe clamps. In short, they're everywhere.
Hope this helps.
