About the Machinist’s Parallel Bar Set

Parallel Bars are pairs of very accurate spacers of known height. The tops and bottoms of these 1018 steel spacers are accurately ground and come in a variety of heights. Parallels are typically used to raise a part a known distance while keeping it parallel to the table surface during machining. The pieces in this set are 2-1/2″ long and 1/16″ thick. The set includes five pairs of precision ground steel bars in heights of:

  • 1/4″
  • 3/8″
  • 1/2″
  • 5/8″
  • 3/4″

Unlike the imported parallels we used to sell, these parallels are now made in house by Sherline. We cut 1/16″ thick, 1018 sheet steel to size using our waterjet cutter and then grind the pairs to the exact height. The finished, ground parts are then sent out for a black oxide finish to keep them from rusting. This set incorporates the quality and accuracy you expect from parts made with pride in our own factory.


The MASSO G3 CNC controller, power supply, stepper motors, cable system and optical encoder are sold as a part of our Accu-Pro line of machines and are not available for purchase separately or as an upgrade option to existing machines.
