Value Collection 20PR Blk Thin Parallel Set 40 Piece

Product Description

The VALUE COLLECTION 20PR BLK is a 40-piece thin parallel set designed for precision machining, setup work, and fixturing in machine shops and toolrooms. The set includes 20 matched pairs, each measuring 6 inches long and 1/32 inch thick, with a maximum height of 1-11/16 inches. Height increments step in 1/16-inch intervals, allowing machinists to establish consistent, repeatable workpiece elevation across a range of setups. At 50 Rc hardness, the parallels resist wear and maintain dimensional integrity under repeated clamping and positioning use. Parallelism tolerance is held to 0.0001 inches, making these suitable for applications where precision matters.

This set is used in milling, grinding, and drilling operations to support and elevate workpieces in a vise or on a surface plate. The thin 1/32-inch profile makes these parallels particularly useful in tight setups where standard-width parallels would interfere with the workpiece or toolpath. Machinists, tool-and-die makers, and CNC setup technicians are the primary users. The 20-pair configuration provides a graduated range of heights in a single set, reducing the need for multiple individual parallels during complex setups.

Key Features

• 40 pieces total, supplied as 20 matched pairs for balanced setup work
• 6-inch length accommodates standard vise and fixture spans
• 1/32-inch thickness fits tight clearance setups where wider parallels will not
• Height range steps in 1/16-inch increments up to 1-11/16 inches maximum
• 50 Rc hardness resists wear under repeated clamping and handling
• Parallelism tolerance of 0.0001 inches supports precision workpiece positioning

Compatibility

Designed as a general-purpose thin parallel set suitable for use with standard milling vises, surface plates, and fixturing applications requiring 6-inch parallel stock at 1/32-inch thickness.

Installation Notes

Parallels should be cleaned and inspected for burrs before each use to maintain accuracy. Always deburr and wipe contact surfaces before placing under a workpiece in a vise. Store the set in its case or a designated holder to prevent nicking the precision ground faces. No special tools are required for use, but a torque-controlled vise handle is recommended to avoid distorting the parallels under excessive clamping force.
