Description
10 Pairs Precision Ultra-Thin Parallels made of premium alloy steel, hardened, stress-relieved, and precision ground. Superior surface finish: Ra0.4um, high hardness: 56–61HRC, long service life. Edges are slightly beveled.
High perpendicularity, parallelism, dimension accuracy.
- Height ±0.01mm
- Thickness ±0.01mm,
- Used in pairs: ±0.01mm (height/thickness)
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".
Convenient to use and maintain during the drilling, milling, assembling work, convenient to clamp workpiece, and provide the reliable and accurate position for workpiece
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.
