Description
20 Pairs Ultra-Thin Parallels. These parallels are 1/32" x 4" which makes them ideal for precision setup and work holding when standard parallels are too thick.
Made of high-quality steel, stress relieved to prevent distortion and hardened to RC 50-55.
Parallels are precision ground for accuracy to parallelism of +/-0.0001".
The heights of the parallels are: 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8", 15/16", 1", 1-1/16", 1-1/8", 1-3/16", 1-1/4", 1-5/16", 1-3/8", 1-7/16", 1-1/2", 1-9/16", 1-5/8", and 1-11/16".
Chris' Tips
These ultra thin parallels are great when you need to drill holes near the edge of your workpiece because they are only 1/32" thick.
The 1/16" steps give you lots of options when working on thin pieces.
The 1/16" steps give you lots of options when working on thin pieces.
Vise jaws are often too deep for the work. In general, you want the top of the work piece to extend above the top of the vise jaws. To fill the gap from the bottom of the work piece to the "ways" of the vise, you use parallels.
Parallels are strips of metal that have been carefully ground so that the top and bottom edges are parallel with very tight tolerances. They usually come in matched pairs. Place one parallel adjacent to each jaw in the vise and place the work piece so it rests on the parallels.
