Orion Hardened & Ground Parallel Pairs - 100x3x21mm

The ORION Hardened & Ground Parallel Pairs in the 100x3x21 mm size are two precision blocks designed for accurate parallel mounting of workpieces in machine vices, on machine tools, or fixtures. Sized at 100 x 3 x 21 mm, these blocks sit flush and square with the tooling axis to help you achieve repeatable setups right from the start.

Built for real-world use in busy workshops, the parallel pairs are hardened and ground to maintain accuracy over many cycles, even with frequent clamping and release. The combination of tight tolerances and durable surfaces supports reliable performance across daily tasks and demanding applications.

• Precise matching tolerance: Matching pair tolerance of 0.01 mm and nominal tolerance of +/-0.02 mm ensure the blocks remain parallel and aligned, reducing setup time and minimizing misalignment between paired pieces.
• Hardened and ground durability: Hardened steel with ground surfaces provides wear resistance and smooth contact, helping maintain accuracy and extending life in repetitive clamping cycles.
• Designed for reliable parallel mounting: Specifically engineered for parallel mounting of workpieces in machine vices, on machine tools or fixtures, delivering flat, square clamping and dependable results across applications.

Using these parallel pairs helps you streamline setups, improve consistency across runs, and achieve repeatable, high-quality results. The precise tolerances and robust construction translate to fewer reworks and more predictable outcomes, whether you’re fabricating, assembling, or prototyping.
