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".

Natalie M. ★★★★★

Exactly what I needed for tight setups where my old parallels wouldn't fit—the 1/32" thickness makes all the difference. The steel feels solid and stress-relieved, with no visible warping out of the box.

William H. ★★★★★

I was worried about finding parallels thin enough for my surface grinder setup, but these 1/32" by 4" blanks slide right under the workpiece without any binding. The steel feels properly hardened and ground, and the 20-piece pack gives me plenty of spares for different jobs.

Scarlett ★★★★★

The 1/32" thickness is exactly what I needed for leveling small parts that my other parallels couldn't handle. The steel feels solid and the 4" length fits perfectly across my vise jaws without any flex. These are going to get a lot of use in my setup routine.
