Thin Parallels, 3" Long, 11 Pairs 

These 3" long thin parallels are great for the small 3"-4" vises used on most mini mills.

This set of 1/8" thin parallels contains 9 pairs of parallels that step in 1/16" increments from 1/2" to 1". This gives you more sizes you can use in our small vises whose jaws are usually about 1" in height. No need to toss the taller sizes in most standard sets.

The two pairs of shims, 9/64" and 5/32" high means that you can space things in 1/64" increments.

Parallel within 0.0002" on the top and bottom. The pairs are matched in height within 0.0002"

Made of high grade alloy steel hardened to 52 to 58 Rc
