Mitutoyo 985-130 Adjustable Parallel Set 4 Piece

Product Description

The MITUTOYO 985-130 is a 4-piece adjustable parallel set designed for precision workholding and setup work on machine tools, surface plates, and inspection fixtures. Each parallel expands across a range of 0 to 1.94 inches, allowing the user to dial in exact height settings for milling, grinding, and boring operations. The set provides a compact minimum length of 0.375 inches, making it suitable for close-tolerance setups where fixed parallels fall short. Machinists and tool-and-die professionals reach for adjustable parallels when a job demands repeatable, custom-height support under a workpiece.

Adjustable parallel sets like the 985-130 are used in machine shops, toolrooms, and precision inspection environments. Typical applications include supporting workpieces in vises, establishing reference datums during layout, and providing consistent height blocks during grinding or milling setups. The 4-piece configuration covers a practical range of common setup heights in a single kit, reducing the need to stack fixed parallels or shim individual pieces.

Key Features

• Adjustable range from 0 to 1.94 inches accommodates a wide variety of setup heights
• Minimum collapsed length of 0.375 inches for tight, close-clearance workholding setups
• 4-piece set provides multiple parallel pairs for simultaneous or varied use
• Compact form factor suits both vise setups and surface plate inspection work

Compatibility

Designed as a general-purpose adjustable parallel set suitable for use with standard machinist vises, surface plates, and precision inspection fixtures where a height range of 0 to 1.94 inches is required.

Installation Notes

Adjustable parallels are set and locked by a qualified machinist before securing the workpiece. Ensure the parallel is fully locked at the desired setting before applying clamping force to avoid slippage during machining. Inspect parallel surfaces for burrs or chips before each use to maintain accurate seating. Handle with care to preserve surface finish and dimensional integrity.
