Starrett Adjustable Steel Parallel Range

The Starrett adjustable parallel (also called an adjustable steel parallel or expanding parallel) is a precision machinist's tool. It gives you a flat, parallel support surface at a height you can set yourself. Machinists use it for work holding, setups, layout and inspection. It can replace a stack of fixed parallels or shims.

Key Features:

• Two-piece steel construction. The halves slide against each other to adjust the working height.
• A locking screw holds the chosen height firmly in place.
• Hardened and precision-ground steel gives good wear resistance and keeps the surfaces flat and parallel.
• One adjustable tool covers a range of heights, so you need fewer fixed parallels in the shop.
• Useful in milling machine vises, on surface plates, and on grinding and inspection setups.

Starrett has made precision measuring tools in the USA since 1880. Its tools are known for accuracy, durability and consistent quality. This adjustable parallel line suits toolrooms, machine shops, fabrication shops and home workshops.
